  • 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

  • Boss quality at a remarkable price
Style: 400W 4 Channel
I've had Boss equipment my whole adult life: guitar effect pedals, MIDI equipment etc.. I paid a little extra however it would consistently outperform it's competitors. Frankly I bought this because my car system was on a budget, it's the best amplifier I've ever had. Plenty of power. I was expecting to have to mess with filters and transformers to eliminate noise in my 1968 Plymouth, especially from the alternator. Lo and behold NONE! Use top quality cords, I used a 10 foot Rica tipped 6 in one. Ground it well, Spend a little extra on speakers you'll love the sound. ... show more

  • 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

  • Buy This If You Like To Solder
Style: 400W 4 Channel
This amp was delivered last night Sept 30. Inexpensive amp, that sounds great when it works. After installation, I had sound out of 3 channels. Checked my wiring first thing. Intermittently I pushed on the speaker outputs and it would work, then not. Uninstalled unit and opened it up. This is what I found. Broken solder joints. So in a nut shell, before you buy one of these. REREAD MY REVIEW TITLE. ... show more

  • Another home run for BossAudio
Style: 400W 4 Channel
I purchased this as a replacement for the same unit that I inadvertently fried while troubleshooting another issue I had with my stereo. I was very happy with this amp running my tweeters and full range dash 3.5 coaxials. Just the right amount of clean power at a price point others couldn't match. I am running this 4 channel amp, another much larger 4 channel amp and a really powerful monoblock amp for the low end going through two dsp EQ's and then a true bandpass three way electronic crossover all except the dsp's, BOSS products. BOSS Audio products in my view are the best quality with the best bang for your buck available today. ... show more

  • Noise Problem
Style: 400W 4 Channel
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. :) ... show more
