This is a nice looking AMP. it was just too much for my needs. They accepted my return.

Perfect

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!

I give it a four star. Only really because it's affordable. But first thing I don't really think it's pushing that many watts. I'm thinking more around like a thousand maybe. I don't know I could be wrong but that's just my opinion that's what I feel. I've got mine hooked up to two 6x9 pops and one little 8-in pioneer cheap ass subwoofer and The pops are bridged so I'm only running three speakers off of it and I think it's still not performing all that well. But like I say for the price I don't know if you could beat it. I bought a smaller one because I was installing new stuff in my Jeep and I just had four little six by fives but it was certainly underpowered. I don't know though for the price you know if you're not pushing really big speakers I guess it would be okay. I mean for 170 bucks can you really beat it probably not.

This thing pounds

PV3700: I bought this to replace factory system in a 2000 Cadillac DeVille. Now I didn't need massive bass. That was not what I was looking for. This amp is a 5 channel amp. This allows for all 4 door speakers and a sub in the rear deck. Tuned amp for door speakers. I tune via multimeter and set channel 1-4 based on speaker RMS wattage at 3/4 head unit volume. Checked my math and channels 1-4 achieved correct RMS rating. 5 star to this point. Now comes the subwoofer/channel 5. I always tune with bass boost OFF. Tuned for 150 watts and blew an old subwoofer up. Not the amps fault as I didn't remember why this sub was laying around. Bought a new sub that has 250 watt RMS rating. 500 watt Peak. Tuned for 250 watts and worked great. Did a test tune to achieve 500 watt and the amp will not go high enough to get to 500 watt on sub. Tuning test was done with bass boost MAXed out. Channel 5 maxed out at 361 watts. 4 star now. Even though it is not that big of an issue for my goals it is false advertisement as BOSS states 563 watts RMS on 5th channel @4 ohm. When you calculate the amps fuses * voltage, 80*14.4=1,152 watts assuming 100% efficiency. A/B amps top out at 65% efficiency so that makes it 748.8 watts MAX output. That is FAR FAR FAR below the 3700 watts advertised. 3 star. All test tuning was done WITHOUT speakers hooked up as that can be very loud. All Speakers used are 4 ohm speakers. Math is WATTS*OHMS=# SQUARE ROOT OF #= VOLTAGE AC to set amp output.However for my application this amp does the job that I ask it to. If you are replacing a factory amplified system and not really adding much this amp is perfect for that application. You are not going to win competitions. You are not going to have the best sound system in town. But you will have a all-around nice system.Pros: Replacing factory system on budget. Channels 1-4 are as advertised. Sound is very clear on channels 1-4.Cons: Amp is lacking advertised power. Channel 5 RMS maxes out at 64% of advertised power. Total MAX power output is 54% of RMS rated output.

I bought this amp for my wife as a early Christmas gift.The 5 channel amplifier that it replaced was over 25 years old.I saw the Boss amp and it was within budget.Well I installed it today and so far so good.If you don't have a big budget then I'd say this is worth looking at.

I bought this amp along with 4 DS18 PRO-GM6B Loudspeaker - 6.5", Midrange, Red Aluminum Bullet, 480W Max, 140W RMS, 4ohmsSo far it’s been heating up after 45min of play at 3/4 volume, it’s advertised to run a up to 3 subs, so I bought 2 ct sound 6.5 subs 400watt rms each, can’t play more than 20 min and goes into protection mode, also the ground screw stripped the threads, overall it’s not what it’s advertised to be, will be trashing it.
