Style: 3700 Watt 5 Channel
I bought the 3700 Boss 5 channel amp with a goal of a well balanced sound for all types of music. Not only did I hit this goal, but it's louder the I ever imagined. I have my Boss Amp hooked to two 6.5" 3 way 300 watt boss door speakers With tweeters in the front, two 6.5 two way speakers and tweeters in the back, and one 1100 watt 12" Pioneer Comp Sub in the cargo area in a 2004 Tahoe. I added a Capicitor mainly because I got it as a bonus. FYI, Before I had the capacitor installed I didn't have any issues with power. I am using 8 gauge power and ground wires, and 6 channel Stinger RCA cables. I did run into some engine noise at first, but then I found out you need to run RCA opposite side of power wire. Rookie mistake on my part. Once I changed my mistake by re running my RCA cable away from my power Line, all my interference noise stopped. when I read some of the bad reviews, I felt the problems people were having was due to improper installation. So far one month after my installation my intuition was correct, because I have yet to have any issues that wasn't corrected from me being a rookie. Matching your gains on all amplithfilers is very important for audio quality and Ampliphier performance. This is the main problem for all Ampliphiers not performing correctly and not lasting. There are Lots of helpful hints if you search How to tune your AMP on the internet. I'm guessing this could be some of the problems the lower reviewers guys could be having. This AMP gets plenty loud, and provides lots of power. When I run music at normal levels My AMP stays cool and runs fine. When you run it hard it does get warm but not to hot to touch and sound great. I installed this under my passenger seat in my 2004 Chevy Tahoe and it fits perfect. People with smaller cars pay attention to dimensions because this AMP is a monster. My friends were easily impressed by the sound and the cool look the way it lights up especially at night. I went expensive on an Apple Car play receiver and Boss really helped me out by giving me an affordable option to continue to add to my expensive receiver at a very affordable price. It's a no brainer if you're in the market for a dive loud system, just make sure it's installed correctly before writing a review. I made lots of mistakes but after researching my problems I got it performing like a Boss! The Phantom 3700 gives you plenty of options to achieve your goals and a great option for people with limited resources. Keep in mind when you're costing Ampliphiers out, the hardware such as wires cables conectors ect: can get very costly ontop of your equipment. I spent almost as much on hardware as I did on the Amp. Boss makes this less painful by giving you such a good deal from the start. I decided to spend less money on the Amp and more money on the correct wires and cables. Try it out, install it right and you'll Love it!

Very good amplifier. Looks great especially when on at night. I’m not using the bass control on this amplifier. My audio system sounds great. Good value.

This is a great amp for the price...It sates that the max power is 3700W but really it's not nearly that. That's BOSS for you though, but It's at about 1920W Peak Max Power at 2 Ohms and it's around 960W total RMS at 2 Ohms. This is true because of Ohm's Law. I saw that it has only two 40A fuses which gave it a max current handling rating of 80A. If you use an Ohm's Law calculator for the total power output @ 80A with 12V you get 960W RMS at 2 ohms. And 480W total RMS at 4 ohms. This is why it's only $125.99. But don't count it out, it still will deliver PLENTY of power for your set up even at 4 ohms. Only thing I would recommend is run your subwoofer(s) at 2 ohms if you can because I have two 8" subs at 4 ohms and it only gets really loud (enough to blow the subs, @300W RMS total together) if you crank up the input and bass boost to max. At 2 ohms I barely had to turn the bass knob and it was about to blow one of my 8's even with the input and bass boost turned all the way down. So you can definitely run two 12's or two15's subs easily if you wire them @ 2 ohms. I use this amp to power my home computer audio and I have this hooked up to an AZZA 1000W 80 Plus Bronze Computer Power Supply which has a max 12V current of about 70A for me to power this amp. I have 12 speakers total hooked up to Channels 1-4. Ch 1-2 @4 Ohms and Ch 3-4 @ 6 Ohms. I have two 8" subs hooked up at 4ohms on subwoofer Channel 5. You can even hook up left and right subs on the channels 1-4 if you use some crossover inductors and capacitors that is described in the Manual. This amp gets ridiculously loud and sounds very clean compared to my old PylePro PTA2 amps. Very loud fast on the channels 1-4 if you run your speakers on them at 2 ohms. I first had my speakers wired at about 2 ohms and I only had to turn up my PC volume level to about 15-20 out of 100 and it was already putting out about 80+ decibels without the subs hooked up. So I had to rewire my speakers with higher ohms so it wouldn't get as loud so fast. If your wire your speakers at 8ohm instead of 2 it also reduces the amount of hum, buzz and hiss sounds coming out of the speakers when no sound is playing. The higher your ohms the less distortion you hear of that, but I wouldn't go past 8 ohms. All in all I am very happy with this Amp. It has nice aesthetics with the red LED glow and feels like it is well made. Only complaint is I wish BOSS would rate their products at true rated power levels. That is why when you buy Kicker or Rockford Fosgate or other high quality brands they always use their Amp's or Subs total RMS rating as what they advertise it at. So I took off one star off for that. Otherwise I am happy with this Amp it took my entertainment centers audio quality to a much higher level and I am very pleased.

Sounded good for 15 minutes until the mounting bracket at one end broke off in the amp nosedived best $171 I've ever spent. What's the point of making something if the metal that you're building it out of is weaker than a freaking twig. Thing is you can say something about it and they say it was your problem. Your fault stop making stuff out of thin pot metal!!!!!
