BOSS Audio Systems R3002 Riot Series Car Audio Amplifier - 600 High Output, 2 Channel, 2/8 Ohm, High/Low Level Inputs, High/Low Pass Crossover, Full Range, Hook Up to Stereo and Subwoofer, Class AB

***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!!!

Works very well

Channels 3 and 4 had no output at all and the 2 channels that did work didn't sound any better than the cheap aftermarket radio. Not sure why I need to run 8 gauge power and ground cables to get no better sound than a regular radio, a lot of work for nothing.

Exactly what it says. You get what you pay for. I knew I was buying a cheap amp when I bought it. Don't go into it expecting $500 sound. It puts out it's rated power...sort of.They DO tell you the true RMS @ _ Ohm ratings of it in the manual and fine print but the packaging and box does the usual flea market audio trick...you know, the whole overrating the power output. Throwing 15000 Watts at you for $30...Yeah, that thing.I would NEVER use this with a woofer of any kind. It does a noticeably better job than my Alpine headunit for powering the front and rear speakers but that's about all I would recommend doing with it. The amp performs well under a seat and I haven't noticed it getting unusually hot or any cut outs. It's quite small which is nice for tight fits. It's comparable in size to a typical factory amp.I did notice that Amazon claims it has a remote subwoofer level control... Well, I didn't notice anything like that in the box. Not a big loss.At the end of the day, it's a $30 amp. It'll do a better job powering your mids than your headunit or factory amp but that's all it's good for. Good little amp for the money. Nothing more. Nothing less.

I installed two under seat subs and eight and a 10 in the driver and passenger side and later over 120 ft of wire in my car with this amp connected to the front two and rear two speakers.I want to say it's like day and night with this amp for the way the speaker sound, they sounded okay but now they sound great and with the addition of the subs I haven't had a car that had such full range and clarity before great product a lot of work very affordable.

The first one I received I didn’t even hook up, when an opened the box the amp smelled like it had already been burnt up. Sent it back got another, this one works but has the most annoying buzz very loud. I got this amp because it’s small and fits inside a box I’m making. Will replace this one when I find another small amp.UPDATE: bought a good ground loop idolater and it solved the buzz issue.

Obviously there are hundreds to thousands of reviews on this "400" watt 4 channel amp, but with all that in mind, I decided to purchase this for a Lincoln SUV to give the factory speakers an extra boost. Arrived within 2 days, took me about 30-45 minutes to install (wiring was already in place from a previous project) and I have to say I'm honestly impressed. Now it's definitely not 400 watts or anything close to that as far as power output goes, but it definitely pumps the speakers up so they sound nice and clean. At first I had this amp powering up 4 Boss 5x7" 3-way speakers, and those sounded terrible but that was the speakers, not the amp. Put the factory 6x8s back in and WOW it sounds good. I didn't notice ANY alternator whine, feedback, buzzing, or any other noises that other reviewers had pointed out. This amp has been installed for about a month now, I waited to leave a review so I could see how it held up over the last month. So far, so good. Especially at this price? Definitely recommend!

For the price, you can't beat it.. this thing has some power
