***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!!!

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.

Excellent replacement for OEM system. Small powerful amp. Only setback is that has no crossover, full range only with volume (in voltage) control.

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.

Good value, worked great

This little amp seemed like it would work just fine after I installed it. Sound wasn't great, but i must admit it was at least as good if not better than expected for the price. Then I turned the ignition on, and the noise was insane! Buzzing, repetitious clicking, whine, etc.. It was the worst I've ever heard, truly, and i've owned some pretty cheap amps before. Anyway, I tried a Boss inline 12A power filter. Works great sometimes, but in this case made it worse actually. Then I tried an old in-line RCA filter i had thrown in the electronic scrap box because it didn't work and I couldn't return it. It worked on this amp! This is a Left/Right RCA filter that says "20 Amp High Quality Noise Suppressor Isolation Transformer" on the outside housing. It didn't work for the application I bought it for (so I got a BSN40 and it did work.) Glad I saved this one though, because it killed every noise the amp was making and sound quality was not compromised. The bass might actually be slightly richer/deeper now on this full frequency range application, but i'll have to find another filter exactly the same for the other 2 channels. I see several sources here that sell what appears to be it, but you never know with generic label stuff like this. So if you have this amp and don't know what to try next, the filter I suggested worked perfect for me, even though 2 of them cost as much as the amp does. :)

Good quality

It's a cheap, inefficient, class a/b amp. It's not winning any awards at show, but its driving a 12" and adds a little bass to my meager system in my daily driver. I've had this for 4 years now. It survived a car flipping end over end early in its life while being completely unsecured. A little dented and bruised, it has continued to serve faithfully through the years since. If you need something modest, you don't need to blow the latch off your trunk, and don't want to spend a lot of money, this is a decent amp for the cost.
