What to know when shopping for car amps
For years some car amp manufacturers have sold their products with outrageously large power ratings on the box. Sometimes these have been simply unbelievable for a budget car amp. For example, hardly anyone would believe that an amp that measures about 12″ x 12″ in size could produce around 1000 watts of power, right?
But for the new buyer who isn’t aware of it, it’s a misleading and confusing thing to try to figure out. That’s what I’d like to help you with.
What do car amp power ratings mean?
Realistic power ratings use the “RMS” label, which is an electrical engineering term to represent “root mean square”, a mathematical way of expressing the actual, useable power that an amplifier can produce continuously.
The confusion comes from amp manufacturers using the “peak” power rating, which is not at all representative of the actual amount of power an amp can drive your speakers with.
Think of it like the example of a modest-sized car with a speedometer that goes up to 200 MPH. Can most average cars really drive that fast? No way!
In the 2000s the Consumer Electronics Association (CEA) developed a standard to help consumers with this. Audio amplifier manufacturers whose specs are listed as “CEA-2006 compliant” have power ratings and performance specs that are reliable.
This logo means that the company making an audio product has reliable performance & power specs. But it’s not a mandatory compliance feature – many companies still have specs on their products which you’ll have to simply hope are correct. Be aware that often you’ll find products that might not live up to advertised power ratings.
Not all companies provide this so it’s important that you’re careful when shopping.
If a manufacturer doesn’t list their specs with some type of standard like this or highly detailed information instead, you’ll basically just have to trust (or hope!) that the RMS power and other specifications are correct.
It’s important to understand this because budget amplifiers often are not CEA-2006 compliant and still, to this day, use the “peak” power ratings on their packaging and sales info. It’s a shame, as it’s very misleading.
Car amp features to look for
I recommend at least a power rating of 50W RMS into 4 ohms per channel for driving full range or component speakers and 150W into 4 ohms minimum for driving a subwoofer. This is generally enough power for the average person to listen to music with enough power for good volume, clear and non-distorted sound, and to be able to blast your favorite music.
Don’t buy an amp with close to 25W RMS or less unless you have a specific reason to do so. Car stereos, for example, have a typical power output of about 14W RMS per speaker channel.
That’s because they can’t produce higher levels of power as they’re limited to using the 12V supply in a vehicle unlike high-power amplifiers.
Mini amps like this one are advertised with power ratings like “200W” which is impossible for it to produce – you have to read the fine print for the RMS power ratings, and even then be cautious. I don’t recommend tiny amps like this except for the smallest basic installation, like for driving small speakers. They can’t produce good sound & power like “real” car amps. They typically lack features you need like crossovers and bridging.
Higher power amplifiers use a special power supply to step up the car voltage and produce higher power output. The problem with small amps is that you will be misled into thinking they can produce higher power than they can.
In fact it’s impossible for such a small amp – you’re still limited to power levels around the same as a car stereo.
If you’re not wanting great sound and are simply trying to power some small 2-way (or similar) speakers, that’s ok. However, these tend to be tiny, low-quality amps I wouldn’t recommend. Also, most mini amps can’t be bridged.
Amplifier high or low-pass crossovers in amps work the same as those using larger components on speakers, called “passive” crossovers. The difference is that tiny, low-power circuits are used in amps for the same results.
Crossovers are great to have! Also, the great news is that they’re much more commonly found in car amps today than in decades past. They are more or less standard on most sold now.
High or low-pass crossovers work to block a range of sound you don’t want to send to speaker channel or channels.
For example, you can use the high pass feature to block low-end bass that small speakers can’t handle well. That prevents distortion and by doing so you can really crank your music for great volume and clear, crisp sound!
A great example is setting the high-pass crossover switch on an amp to “HPF” and the control to about 60Hz. That way everything above 60 Hz (a low bass frequency) would be played but not below.
Crossovers and other related controls like those on this excellent Alpine MRV-F300 4 channel amp are extremely useful. They’re pretty much mandatory for getting lower-distortion, high-volume sound with great clarity. You simply turn the switch to LPF (low pass filter) or HPF (high pass filter) as needed and adjust the cutoff frequency by adjusting the dial.
The result when using a crossover for small speakers is more volume and clarity at higher power with less distortion.
For subwoofers, a low-pass filter means pure bass without hearing the vocals and other parts of sound a subwoofer doesn’t do well and will sound terrible when allowed to play.
Bridgeable amps are those that are designed to allow using 2 speakers channels together in a push-pull way to get substantially larger power out of the amplifier.
There’s no magic behind it: it’s basically just using more amplifier output channels together in order to drive speakers with more power.
When a speaker is connected across 2 speaker channel outputs the amp can produce up to 4 times the power of a single channel! (This depends on the particular amplifier)
It’s a great way to have an amp that’s flexible for use with multiple speakers or to get more power for driving a subwoofer. I’ve covered this in more detail in my post about bridging amps here.
Class A/B vs class D amps
Class D mono car amplifiers use new fast-switching technology to deliver a lot more power with less space AND using less battery current. They work by chopping up the musical signal into square waves which switch transistors on and off rapidly, saving energy use. Finally the output is created by restoring the musical signal, filtering it, and driving speakers
Amplifiers fall into “classes” (design categories) based on the type of technology they used to boost power and create an amplified audio signal to drive your speakers. Class D is the newest and most efficient technology while class A/B is one of the oldest.
A/B generally has been used in most budget amps (which is fine – it produces good sound quality, but uses more electrical power).
Class D amps are much more compact in size, but the best class D amps which improve the one drawback of the design, higher noise, are generally close to $150 and above. The best ones are designed by major companies. The lower cost amps you see will probably be class A/B, just so you know.
What to expect when shopping on a budget
When choosing a budget amp, consider all the things I wrote above as well as understanding that the least expensive amps are a compromise.
Expect good quality and performance but not the same level as you get for more expensive models.
Budget car amp shopping tips
- A good budget amp will have a combination of the features you need, sufficient power, and overall good buyer reviews
- Remember that many buyers have unrealistic expectations of budget amps and leave negative reviews – always read more and look for general patterns before deciding
- Budget amps commonly use “peak” power ratings for sales purposes, rather than continuous RMS power or CEA-2006 industry-standard ratings
- Don’t forget you can add a 2nd amp later when your budget allows!
- Get a decent quality amp wiring kit when purchasing your amp. You’ll save both time and shipping costs
They simply aren’t designed the same way as the big name brands which cost more. It’s always important to keep things in perspective.
On the other hand, when you’ve got a budget, you’ve got a budget to keep! I’ve been there and know how it feels – and that’s totally ok.

I’ve been enjoying Alpine’s great engineering & sound quality for years. To this day they’re still one of the best brands when it comes to mobile audio.
The compact and great-sounding MRV-F300 is a fantastic example of a car amp done right.
One of the smallest 4 channel amplifiers in its power class today, the MRV-F300 puts cheaper amps to shame. You’ll get a sharp-looking dark brushed metallic finish that’s more expensive looking than it really is.
A great blue power-on backlight indicator provides a cool looking contrast to the amp when switched on.
You’ll get a better-looking installation, too. For more custom installation possibilities, the included end caps can be used to hide wiring connections.
Personally, I think it’s a great touch and works well for flush-mounted amp installs or even just a basic carpeted amp rack.
For under $150 you’ll get some great features:
- 50W RMS x 4 @ 4 ohms power
- 75W RMS x 4 @ 2 ohms
- 150W RMS x 2 @ 2 ohms bridged
Speaker-level inputs are provided and connect neatly using the included wiring harness. Adjustable high or low-pass crossovers provide great system control for excellent sound system capability. A bass EQ feature provides an added bass boost for channels 3/4.
At only 7 7/8″ W x 6.5″ D x 2 3/16″ H (200 x 165 x 55 mm) in size, it can fit into spaces traditional amps can’t!
Alpine has designed the amp using class D technology that provides super-efficient power that’s not just really compact but that runs cool even at full power!
Overall in my opinion the crossover options are good. Features include:
- 50-400Hz high/low pass adjustable cutoff frequency
- 12dB/octave multi-stage crossover design
- Front and rear crossovers are independent
- Bass EQ boost feature for Ch. 3/4.
In my testing I’m happy to say the sound quality is excellent with crisp highs and solid bass and midrange. Noise levels are very low and the sound is surprisingly good!
In my experience, it’s a well-rounded, affordable, and quality amp that won’t disappoint.

For starters, unlike most of the other budget mono amps out there, Rockville provides industry-standard CEA-2006 power specs with proven numbers! It’s also lab-tested to actually slightly exceed its rated power.
Power ratings are:
- 350W RMS @ 4 ohms
- 550W RMS @ 2 ohms
That’s some serious power for an amp that you can find for under $100 if you shop carefully (see my link below). Not only that, but it’s well-made and the features are surprisingly good, too.
(CLICK IMAGE TO ENLARGE)
Unheard of in budget amps, the DB12 includes a certificate of verified power. You won’t find that elsewhere, and it’s a fantastic thing in my opinion. CEA RMS rated power means you’re guaranteed to get an amp that delivers as promised.
The DB12 has PLENTY of features despite its low price and amazing power output. The wiring terminals are far better than other amps in its price range and offer tight high amp contacts for larger wire. You’ll also get a bass EQ feature, 0/180 degree phase control, and an adjustable low pass filter. There’s also a bass remote port and RCA pass-through jacks. Wow!
What really surprised me about the Rockville DB12 isn’t the amount of power you get for the price, even though that’s pretty fantastic. It’s the features that really put it head and shoulders above the rest.
You’ll get all of this, too:
- Includes bass remote and cable
- High-current wiring terminals
- Certification sheet with tested power and serial number
- RCA line out jacks for expansion
- 0/180° sub phase control switch
- Subsonic filter
- Bass EQ feature
- 0-250Hz adjustable low pass filter
- Soft on & mute start-up circuits
- Overheating and short-circuit protection
- LED illuminated logo
- Bass remote features a power LED
You’re simply not going to top this list of features an anything else I’ve seen in this price range. Without a doubt it’s one of the rare few to offer true CEA-2006 power ratings.
Included with the DB12 is everything you’ll need to get started aside from the wiring kit and a signal source: Allen wrenches for the speaker terminals, mounting screws for both the amp and remote, an owner’s manual, and the remote + easy-connect cable.
Is it perfect? Certainly not. I do have a few complaints.
Mainly, it can’t handle 1 ohm speakers so you can’t drive some subwoofer setups like other amps. Additionally, if connecting to a factory system you’ll need an RCA speaker level converter as speaker level inputs aren’t provided.
The Rockville DB12 is an amp I thought I’d never be awarding my Editor’s Choice best value award to. However, I can’t argue with the facts: it’s an excellent budget bass powerhouse that’s affordable and ticks all the right boxes!

Best Inexpensive Amplifiers (Single Channel)
A single channel amplifier differs from conventional amplifiers in that it only outputs one channel. They are no longer suitable for anything other than woofers. Therefore, they are also called subwoofer monoblocks. Their entire design is focused solely on amplifying and improving the sound of low frequencies. Among the features of this type of amplifiers are the following:
- Convert any signal to mono mode. Even if it receives a stereo signal from the radio, it sums it up and outputs a mono signal going to the subwoofer.
- Mandatory high pass filter. With its help, all frequencies belonging to the range located above the filter are cut. This is necessary for better sound quality of the subwoofer.
- The presence in many models of the so-called subsonic. This filter is designed to cut off ultra-low frequencies located in the range from 5 to 30 Hz. This is very important, because hitting these frequencies on the speaker can lead to a quick failure. This is especially true for bass-reflex subwoofers.
- Very high power. With a load of 4 ohms, the channel power does not drop below 150 W, but more often it is much.

How to choose a car sound amplifier
Due to the fact that the main purpose of the amplifier is to improve the sound quality, it is necessary to approach its choice responsibly. In order not to make a mistake with the choice, you need to focus on the following parameters:
- number of channels;
According to the first parameter, all amplifiers are divided into:
- A. has a low efficiency, but produces a good sound level with minimal distortion. Consumes quite a lot of energy.
- V. Has high power, but noticeably distorts the sound. They have high efficiency and improved thermal stability.
- C. Sufficiently high efficiency, but produces a distorted signal. Not suitable for high end acoustics.
- A/B. They have average indicators of the first and second types.
- D. Digital amplifiers, powerful and compact, capable of delivering very clear sound.
By the number of channels they are divided into:
- Monoblock. Used to connect a subwoofer operating with a load of 1 or 2 ohms. In case of higher load, it is recommended to use a two-channel amplifier.
- Dual channel. Allows you to connect two speakers or a subwoofer.
- Three-channel. You can connect two speakers and a subwoofer.
- Quadruple. Used to connect four speakers, two speakers and two subwoofers, or a pair of subwoofers.
- Five-channel. Allows you to connect four speakers and a subwoofer.
There are also six-channel models, but they are very rare and almost never used.
As for power, there is a division into maximum and nominal. It is necessary to choose according to the latter, because it is she who indicates the power at 1% distortion.
Which amplifier is better to buy
When it comes to which amplifier to choose, it is also advisable to pay attention to the presence of additional features, such as the presence of low and high pass filters, a fan and an external volume control.
When choosing a car amplifier, you can be guided by this review or user reviews on the Internet. Properly selected device will allow you to enjoy high-quality sound for a long time.
How to choose a car audio amplifier
Favorite music, radio broadcasts – that’s what helps to cope with road boredom. Most motorists pay great attention to the sound system in the cabin. Some are not satisfied with the capabilities of the head unit, others have little volume margin, others do not like the audio environment. A car audio amplifier can solve all problems. This is a separate device connected to the on-board network. Amplifiers for car acoustics are able to work with powerful subwoofers, operate with two, four or more channels.
Voltage: debunking the myths
If we consider the average amplifier for car speakers, its supply voltage is standard 12V. But in some sources of information that are not completely honest, you can find data that this or that device works with 24V. In practice, this means the following:
- in the voltage conversion circuit, the power amplifier has a capacitor;
- when a small input signal is received, the system operates normally;
- at the moments when the audio sine wave rises above the set value, the amplifier starts to be additionally powered by the capacitor;
- the supply voltage is doubled (24 volts), which allows more power to be output.
A similar process must be taken into account if you want to choose a car amplifier with a low price and declared huge numbers of output watts. This means that the device is only capable of short burst volume . It cannot constantly produce the power indicated on advertising stickers. The honest possibilities that a compact monoblock amplifier or another model is capable of are limited by the parameters of the car’s on-board network.
How to immediately outline the segment of acceptable devices
There are a huge number of car amplifier offers on the market today. Models are distinguished by many parameters in which the average buyer can get confused. To choose the right power amplifier, you should consider the requirements for your sound system. What do you want to get, maximum volume or excellent sound quality?
There are other parameters that you need to consider when connecting a particular speaker. The first thing to choose is the sound quality of . It is quite simple to determine it from the documentation for the model. Today, consumers are offered amplifiers of several main categories, with different control schemes for opening transistors.
- Category A . Considered an acceptable choice for audiophiles. The amplifier works with an analog signal, while showing a rather weak efficiency. The output power is low, but the sound quality is beyond praise. Even an inexpensive class A mini amplifier will show an almost complete absence of signal distortion.
- Category B . This amplifier works with analog audio. Transistor on-opening control technology reduces quiescent currents and achieves greater efficiency and output power than class A. However, signal quality is sacrificed. Distortions are present, but for the average listener they cannot be called critical or noticeable.
- Category AB . It uses a hybrid control principle. Thanks to this, it is possible to obtain acceptable efficiency and power, low distortion.
- Category H . These are the most common systems. They will never enter the top car amplifiers, but they are massively found in head units, head units. Class H models use the system of short-term doubling of the supply voltage already described above to surge the output power. Therefore, they are often installed in circuits for an active type subwoofer.
- Category D . Such amplifiers are called digital. In practice, this is not the case. The signal is simply converted using pulse-width modulation technology. Transistors operate in key mode. Therefore, the amplifier has the highest possible efficiency and output power. At the same time, the level of signal distortion is high even for the average listener. The upper frequency range is also limited. Audiophile such sound quality will bring to hysterics.
There are also various modifications of certain categories . For example, AB + offers a mixed type of key opening with a transistor control technique close to class A, good sound quality, acceptable efficiency. There are also solutions for audiophiles. The Super A amplifier is a system where the transistors never turn off, even at rest. With such a control scheme, distortions of small levels of the input signal are neutralized, and non-linearities that occur during the opening of the key disappear.
Number of channels
Each motorist has his own requirements for the interior audio system. For some, two rear speakers are enough. Others want to surround themselves with sound from all sides. We must not forget about lovers of powerful bass and maximum volume. It depends on such desires how many channels the amplifier will have in the car.
Two channel amplifier shows maximum sales. These are pretty simple devices. Two main speakers are connected to them, or a 2-channel amplifier is used as a signal source for a subwoofer. This requires a model that supports bridge switching mode to increase output power. If the parameters of the device allow you to directly connect a powerful subwoofer, a two-channel can feed a pair of low-frequency speakers at the same time.
The popularity of this solution among consumers is steadily declining. The general scheme of connecting two loudspeakers and a subwoofer is inefficient. The system is either not able to swing the low-frequency speaker, or forces you to buy powerful speakers.
The quad amplifier is very popular as a fairly versatile solution for car interiors. 2 speakers and a powerful subwoofer can be connected to it using a bridge connection of two outputs. The 4-channel amplifier is able to enliven two woofers at once, which fans of rich bass like.
An amplifier of this class can be used classically. In this case 4 channels are used by the to connect the speakers. To power the subwoofer, a two-channel is bought, or the woofer is not used, rich bass is created by the broadband speakers of the speakers.
The 5 channel unit is an inexpensive alternative for those who want a quad speaker and subwoofer without buying two amplifiers. The system in single device format is compact. However, installing a subwoofer with high power on a five-channel will not work.
The 6-channel amplifier is not very popular. Its possibilities are simply redundant. The only application model looks like connecting four speakers and a subwoofer in a bridge circuit. However, a 6-channel model is significantly more expensive than a combination of four and two-channel amplifiers.
Main and additional features
When choosing a car amplifier, the buyer always pays attention to the output power. There are several basic techniques that allow you to match the parameters of the acoustics and the signal source, as well as provide them with normal modes of trouble-free operation.
Important! Amplifier power is indicated in Watts, can be nominal RMS and peak PMPO. When choosing a model for your car, in no case should you focus on the latter. It means only a short burst of power and cannot be sustained for a long time. In order for the sound system to work in normal fail-safe modes, the RMS figure must appear in its calculations.
Responsible manufacturers provide real field test data in the passports of their amplifiers. In some cases, a certificate is even attached to the device, which indicates the serial number and brand of the device with which the test was carried out. After the scope of the main parameter, power, is determined, it is worth moving on to considering the additional capabilities of the amplifier.
Crossovers can be called quality filters . They will allow you to adjust the sound ranges for low-frequency, conventional speakers, tweeters. Good amplifiers offer manual adjustment of the cutoff frequencies. There is also a multiplication system that allows you to make per-channel amplification and completely get rid of external crossovers. Higher-end models offer the ability to change the rolloff in dB.
Bass Boost and others
Grand Bass, Super Bass, Bast Boost mean one thing. The amplifier is able to cut off the frequency band and separately process the signal in this range. This is very good if you want to get really rich bass. Good amplifiers allow you to adjust the frequency band manually, as well as independently set the degree of signal boost.
The presence of such an input on the amplifier means that it can be connected directly to the speaker output of the head unit. This is not an ideal method for receiving a signal. The input of the amplifier will receive all the distortion and interference generated by the not always high-quality amplifier of the head unit. But if there is no other option, High Level Input can become a much needed option.
A device that supports the bridge circuit is capable of supplying double the power from a pair of outputs to a single playback device. The presence of the Bridge option is indicated in the documentation for the amplifier. Also on the terminals there is an icon in the form of brackets. On four or more channel devices, you can determine which outputs support bridging.
Tip! This option is extremely useful if you want to use a powerful subwoofer and at the same time save on buying an amplifier.
Almost all car amplifiers have this option. This is low power signal main input . It is to it that you need to attach a playback device to get sound with minimal distortion.
Almost all three or more channel amplifiers are equipped with a fader today. The task of this block is to balance the signal level between individual playback devices . With the help of a fader, it is easy to adjust the sound image in the cabin that is optimal for the owner, balance the front and rear speakers, tweeters.
The best models in terms of price and quality
In the rating of car audio amplifiers, it is unreasonable to include only products that have good technical performance. The main factor is always consumer opinion . Today, music lovers on four wheels are informed, they find information in thematic communities and actively share their experience in using certain models. The top car audio amplifiers include only those devices that show the optimal ratio of functionality, sound quality, cost and ease of installation and configuration.
