Sample Customer Review:

“At first i thought it’s only 1600 x 2 and that it would support my speakers or that it might not be able to amplify my music but it proved me wrong. This is a great amp, sounds real good and worked with my speakers and tweeters. I really don’t have a major setup but my speakers and tweeters are more than what the amp distributes making it so that the amp does not burn out the speakers.

It still sounds awesome and i have had any problems. The amp is small, has simple connections and the look of it, give it a great shinny silver color that looks nice in the trunk setup. Overall, item is great and should be considered, plus i recommend it.”

Sample Customer Review:

“Bought this Amp for my dual 12” Kicker Solobaric L7’s in 2020. Two years later the amp still pushes the subs as hard as day 1. Drove 1,600 miles only stopping for gas with the stereo blaring for 90% of the trip and the amp never let up nor did it even feel warmer than the inside of the vehicle.

I have never turned both bass knobs to 100% at the same time, but the amp is at aprox 90% up and has never failed. Absolutely love it and couldn’t be more happy/impressed."

Sample Customer Review:

“I bought this amp just wanted to test it out and not expecting it to work very long. When I first received it, it did not look or feel very bad. The amp itself feels sturdy and of some quality. When I hooked it up to my Massive Audio hippo series 8” sub I didn’t set the gain as high as I could’ve just to see if it would work and it did. I turned the gain up to where it should be and it has been running for 4 months without any problems.

I waited to do a review to see if it was even worth my time and I’d say so far it’s worth it to tell everyone how it did. I think maybe some people with 1 Star reviews either just got a bad lemon or were trying to push too much with it. I’d definitely say this is for a simple set up, not for completion or any extremely high wattage subs. Overall my expectations were exceeded and hopefully this amp will continue to work. I will update this if anything else happens worth knowning."

“Like many other amps it has a super small tendency to have a background noise. But I’m talking small, engine running and you need to listen for it and intermittently happens. Truly no amazing for the price and overwhelming quality of sound and power it helps project through my speakers.

Highly recommended and also works great if you only want to run a subwoofer as it has a bypass switch. Manage to also use OeM amp wiring with no issues or clipping.”

Sample Customer Review:

“I recently upgraded my stock speakers to JBL components. After reading reviews a lot of people recommended the addition of an amplifier so I got this. I’m glad I did. It really wakes up a system! Sounds incredible. Very powerful and small enough to fit in a storage box under one of the seats in my 2cnd gen Tacoma access cab. Definitely worth every penny. If you upgrading your speakers, I highly recommend the addition of this amplifier. Just incredible, I’m a very happy camper!”

Selecting a suitable car amplifier for under 100 dollars is difficult as there are so many models on the market. However, if you go through the right tips, you can make a wise selection without hassle. These are some key points to consider when you’re selecting a sound amplifier.

You should buy an amplifier that is designed for a particular vehicle. For instance, if you have a subwoofer, then a 2 way or 3-way amplifier will be required. Before purchasing an amplifier, make sure you know what kind of audio system your car is equipped with. This will help you select a suitable amplifier.

You should always check the quality of the amplifiers you buy.

For example, if you plan to install an amplifier in a luxury car, you should look for a high-end amplifier as it will give you better sound quality. If you have to buy an amplifier for a cheap car, then you should opt for a budget amplifier as they don’t offer any high-end features.

You can always buy a universal amplifier. However, if you want to get the best sound quality from your amplifier, you should look for a dedicated amplifier.

Look at the specifications of the amplifier. For instance, if you want a subwoofer amplifier, you should check the power rating and the size of the speaker coil. For optimal results, you should get a high-output amp that will work

You should always buy a good brand amplifier. For example, if you are purchasing a subwoofer amplifier, then you should go for high-end brands like Sony, Onkyo, Bose, Pioneer, etc.

It is unnecessary to buy an expensive amplifier as a cheap one will do the job. For example, if you have a budget of 100 dollars, you can buy an inexpensive amplifier like Denon, Pioneer, Sony, or JVC. So, this way you will save some money.

You can also buy a universal amplifier from any car audio store. However, make sure that it has a high-end design.

It’s important to check the reviews of the amplifier before purchasing it. If the amplifier is not getting good reviews, you should not go for it. You will be able to save money and time by doing this.

Always buy an amplifier from a trusted store as you don’t want to get a fake product.


A decent amplifier will be able to reproduce music at low volume and enhance it in the process. It will also not have a sound that is too “bright.” You can go for an amplifier with a more extensive output, but you’ll have to use a power supply with a higher capacity (this will cost more).

You can go for an amplifier with better dynamics and clarity (which is not as “bright”). As for the frequency range, try to choose an amplifier that goes from about 80Hz to 20kHz.This will let you reproduce most types of music.

If you are concerned about the lowest frequencies, then get one with a wide bandwidth.

You may want to consider getting an amp with a headphone out, so you can listen to the music without disturbing your neighbors. We recommend going to a local shop and trying out several amps. It will be possible to hear which one sounds better. The one that sounds the best will be what you want to buy.
