## Customer Reviews

### ⭐⭐⭐⭐⭐ Power and sound quality in the car
*by R***O on September 10, 2025*

This amplifier exceeded my expectations. The installation was simple and the difference in the car's audio is impressive: the bass is heard deeper, the treble is clearer and in general the sound is much stronger. It does not distort even if it increases the volume and you can see the quality in every detail. In addition, the size is compact and does not take up too much space. Without a doubt, an excellent purchase for those who enjoy good music in the car.

### ⭐⭐⭐⭐⭐ IT’S NOT THE AMP’S FAULT!
*by J***N on July 2, 2018*

***UPDATE 8/4/18***I went mudding a week ago and accidentally sank my jeep in a pond 🙃 Completely flooded the floor of my interior and soaked the amp, luckily it was off. A couple days later I ripped the entire interior out and washed it out really good, like literally washed the inside of my jeep with a hose. I figured the amp had already been soaked what more harm could I do. Got everything back together after drying out, fired up the jeep, turned the stereo on and BAM! Perfect sound quality. If it can get soaked twice and still work I think that says something.*end of update*Did you know, that running your power lead in close proximity to your audio cables can cause loss of sound clarity, distortion, and you guessed it, alternator whine?! I’ve had to fix plenty of botched installs due to this. I did a little test and ran my audio cables directly next to my 4g power lead going to both my amps. Heavy whine and almost no signal clarity. Re routed my cables to run on the opposite side of my power lead and wow! Signal was clear, bassy, and no alternator whine.This amp is phenomenal and woke up the old Bose speakers I pulled out of a 2001 Pontiac GTP (2ohms at 50 watts RMS, give or take). I drive a Jeep Wrangler TJ and space is precious, so I can’t have big amps and fancy subs. This fit under my driver seat perfectly and cranks some serious audio to my speakers, even with the top down. Great price for a quality low budget system and I get lots of compliments from friends. GREAT AMP!!!

### ⭐ JUNK. DON'T BUY.
*by A***R on April 17, 2025*

Bought this 600w two channel amp to run 2 12" subs that are rated for 300w each. Figured it was a good price for what I was trying to do and it worked great,....for about 4 days. Suddenly stopped working when I was out running errands. Fine when I got to the store, nothing when I got out of the store. Literally nothing. No sound, no indication anything is wrong with it, no warning it was defective. Just stopped powering the subs.Still has the pretty blue lights behind the logo and a green light showing it has turned on from the remote wire signal but nothing going to the speakers. Speakers checked out, LOC checked out, even tried wireing up the high input harness just to be sure it wasn't coming from the signal side.Hard wired subs to the speakers in my soundbar (jeep thing) and they're fine. Checked the ground, remote, and power, all fine.The crazy thing is, it didn't blow the fuse on it or on the power supply.Just spend a few extra dollars on something that isn't hoping you mistakenly buy it thinking it said Bose. It's cheap for a reason.At least Amazon didn't hassle me on the return.
