When you see low-priced high-powered car audio amplifiers on store shelves, it can be tempting to buy one. Power Acoustik is one of the most popular car amplifier brands sold at Walmart.

Power Acoustik car amplifiers have an ultra low price tag, yet can provide a tremendous amount of power. That is, at least, according to its packaging. So, you may be wondering, ‘Is Power Acoustik a good brand?

The unfortunate truth of the matter is that Power Acoustik amplifiers are overrated. Power Acoustik advertises the amplifier’s power in peak Watts. Peak Watts can only be sustained for a fraction of a second before losing a tremendous amount of quality. RMS Watts, on the other hand, can be listened to continuously without any distortion. So, Power Acoustik amplifiers generally provide about half of what they claim.

In this article, we will tell you about how Power Acoustik rates its products. Once you know more about the company, you can decide if Power Acoustik is a good brand.

Is Power Acoustik A Good Brand?

Power Acoustik is one of those middle of the road budget amp brands. The company has better tech support than most, and they offer schematics for most of their amps.

The good news is that it’s not very difficult to find out just how bad these amplifiers are. In fact, if you know what to look for, all you have to do is visit the Power Acoustik website or read the owner’s manuals to see that these are not the best quality amplifiers.

Still, many people are wondering if Power Acoustik is a good brand. Power Acoustik’s amplifiers are known to be overrated and misrepresented. Does that sound like something a good brand would do?

Overrating hardware is a deceptive sales tactic. When an amplifier is overrated, that means you won’t really be able to get all the power that is claimed on the box. If you are able to achieve anywhere near the level of power it claims, it will be heavily distorted.

Power Acoustik Amplifiers Are Known To Be Overrated

So, when it comes to Power Acoustik, a good rule of thumb is to assume you are only going to get half the rated power. For example, if a Power Acoustik amplifier is rated for 2000W, then you will only be able to go 1000W before the audio signal is too distorted to enjoy.

Remember, it’s not always the case that you get what you pay for. There are plenty of situations where the lower cost item is superior to the higher priced competition. In this case, however, the low cost of Power Acoustik amps end up to be not worth it.

The amps made by this company are simply too cheap to contain high performance hardware. This makes it so there is no way Power Acoustik amplifiers are going to give you anywhere near the performance that they claim.

Automotive amplifiers are not the only product that Power Acoustik produces. The company also makes speakers, head units (radios), and some accessories. The speakers and head units made by Power Acoustic aren’t nearly as bad as their automotive amplifiers, but they still leave quite a bit to be desired.

What Is A Watt?

In the consumer electronics and car audio markets, you will hear a lot about watts, power output and power handling.

A Watt is an electrical unit for the rate at which energy is transferred. A single watt is not a lot of power. Small devices typically consume power on the order of watts, while the energy used by large appliances is measured in kilowatts (1000 watts).

For example, a company will advertise speakers capable of handling 200 watts or an amplifier that can put out 1,000 watts, which is 1kw.

When it comes to buying amplifiers and speakers, most people simply look for products that can handle the highest power rating according to the box. Manufacturers know this, so this is why some of them go out of their way to be deceptive with the watt ratings on their packaging.

All you really have to do is take a closer look and read the fine print. You will see that some manufacturers rate the power capabilities with peak watts, while others use RMS watts.

If you look hard, you will notice that there are some manufactures that even show both ratings.

RMS Ratings Are More Important Than Max Ratings

When shopping for amplifiers, it may seem obvious that a particular amplifier is better because it can handle 100 watts, while a different amplifier can only produce 50 watts. If you inspect the packaging more, however, you will find that the first amp is advertising peak watts, while the other one is advertising RMS watts

In this example, it becomes clear that both amplifiers are the same: 100 watts peak and 50 watts RMS. There are even some amplifiers that don’t advertise RMS or peak watts, but instead they use a figure called max watts. Those are the kind of amplifiers to avoid entirely.

RMS stands for Root Mean Square. To put it simply, RMS watts is the amount of power that an amplifier or speaker can handle continuously. Running an amplifier at its RMS rating should be safe and sustainable for any period of time.

What Are Peak Watts?

Peak Watts, on the other hand, is the amount of power an amplifier or speaker can handle for a short, specific amount of time. The amount of time this power level can be sustained varies from amplifier to amplifier.

This is because this rating and timescale is actually not particular to the amplifier itself, but instead is governed by the amplifier chips that are used in the amps construction.

Max Watts is how many watts that a speaker or an amplifier can handle before it catastrophically fails. This rating is the absolute maximum level that an amplifier can run at. Any louder than that and the components will fail and possibly lead to fire.

When Shopping For Amplifiers, Don’t Go By Peak Watts

So, when you are shopping for an amplifier or a set of speakers, it’s of crucial importance to look for the RMS power rating. Peak power is not a very useful figure, and max power is an even metric to shop by.

This is because RMS watts is the continuous power handling capability at sustainable volume and quality levels.

The basic rule of thumb is, if an amplifier does not list its RMS power rating then assume any ratings that are given are for peak. And if that is the case, don’t buy it.

For example, the Power Acoustik OD1-7500D Overdrive claims to be able to 7000W, but according to the reviews, it can’t even do half of that.

Brand/ModelPrice WattsWatts per $
Power Acoustik OD1-7500D Overdrive Series$149.99750050.0
NVX XAD14 3000W RMS 1-OHM$309.9530009.7
Sundown Audio SFB-3000D$417.9930007.2

Notice something odd about the chart above? This is an example of how advertising peak watts is a deceptive sales tactic. It makes the cheaper amplifier look like a no-brainer, but in reality, it’s not a good choice.

The NVX XAD14 is a true, fully bridged Class D amplifier. If you are looking for high-power outputs, then this is the amplifier for you. In a full bridge design, using the same DC voltage, maximum output voltage is double what a half-bridge converter can do.

Unlike the Power Acoustik mentioned above, this Class D amp can deliver a a strong wattage output, sustainably.

The NVX XAD14 uses high-quality MOSFETs (Metal Oxide Semiconductor Field-Effect Transistors), which offers a key advantage. MOSFETs require little to no input current to produce large amounts of output current.

Alos, this amp offers state-of-the-art protection circuitry, which is required at these power levels. This extra layer of protection helps to ensure longevity and safety.

Unlike the Power Acoustik model, the XAD14 is a fully bridged 1-ohm stable amplifier. That means you can hook this amp to a speaker system that has just 1 ohm of resistance and you won’t have any problems.

The XAD14 takes music to the next level by generating up to 3000W of sustainable, RMS power output. This is in contrast to the ‘7000’ Watt Power Acoustik that can really only do around 2000 Watts RMS before it becomes too distorted to enjoy.

Who Makes Power Acoustik Amplifiers?

Epsilon. The company sells products under six brands in the automotive A/V sector. Soundstream Technologies, Power Acoustik, Farenheit, and Precision Power are all brands under the Epsilon umbrella.

Are Power Acoustik Radios Any Good?

Power Acoustik makes more than just amplifiers. The good news is that the company’s radio head units are a lot better than their amplifiers, but they still suffer from quality and reliability issues.

What Brand Is The Best For Car Audio?

Pioneer, JL Audio, Boss Audio Systems, Polk Audio, Alpine, and Kenwood are the best brands for car audio equipment. These brands are known for making high quality, properly rated car amplifiers and other equipment.


Power Acoustik car amplifiers have high end specs with low prices, so you may be wondering if Power Acoustik is a good brand.

 Power Acoustik rates its amplifiers in peak Watts. The problem with peak Watts is they can only be sustained for small durations.

High quality amplifier manufacturers instead rate their amplifiers in RMS Watts, which can be listened to continuously without distortion. Because of this tactic, Power Acoustik amps really only produce around half the power that they claim.

We hope this article helped you learn whether or not Power Acoustik is a good brand. Thanks for reading!
