    • IT’S NOT THE AMP’S FAULT!
Style: 400W 4 Channel

***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!!! ... show more

rubbish, it's not worth remembering how I wasted my money and my time with this rubbish, a very bad experience, neither good sound nor power, the stereo alone sounds better and with more power

    • Awesome amp.... While it works.
Style: 400W 4 Channel
As others have said. Static noise. I can live with it as I only heard it a low volume levels. However, after only being installed for 2 months, channels 3 and 4 stopped working yesterday. I swapped rca wires. Swapped speaker wires. Nothing. Channels 1 and 2 still work perfectly. Going to contact Boss to see if they'll replace it but I most likely purchase a different 4 channel amp for my 2018 JLU. 11/13/23 UPDATE: Boss Audio reached out to me after I filed a warranty claim. They had me destroy my current amp, email pictures to prove, and are sending me a new one. I have updated my review from 2 to 4 stars based on the very good customer service. ... show more

Its not like your buying this to push a monster sub. It sounds great on two 6x9s and one 4x10 bridged in my 1966 Continental.

Style: 400W 4 Channel
Hook this up to 4 6x9 sounded the same as the car radio, hooked it up to a 10 sub. Let put it like this the sub moves a little bit, need a bigger amp, that’s my fault I should have known.

I added this amp 400 watt 4 channel to my harmony audio door speakers 300w peak 100 rms. I went from my output of my existing subwoofer amp to one channel and the other channel came from the head unit. I have a ground loop isolator installed on the subwoofer.

Just needed something to drive my aftermarket speakers and this little thing did not failed me, It's actually above my expectations. in the end had to replace my rear speakers to a higher wattage because this amp clearly can supply power to it. If youre looking for something a little above your OEM sound system this amp can provide it. Btw. is you notice the RCA noise filter? the noise is actually coming from the head unit. I just don't have space under the dash to mount the filters...... good luck! ... show more
