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! ... show more

Exactly what I need
Style: 3700 Watt 5 Channel
Stock amp in my 2010 Mazda 3 blew, I needed a multi-channel amplifier to replace it. This just took a weekend to install and works great with stock head unit and stock speakers! So much more power than what I need, but it was 1/2 the price what a replacement crappy OEM amplifer would cost! Make sure to invest in a good pair of wire strippers before installing this, because it's a LOT of wires to hook up. I'm using the high power inputs from a head unit, works great. Lights look cool too but I don't really care. Not beating any audiophile studio grade quality here, but it makes the speakers make noise that doesn't sound like trash. ... show more

Lots of Power for the price, but not truly 3700W.
Style: 3700 Watt 5 Channel
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. ... show more

Nice. Check your head unit before you say it doesn't work.
Style: 3700 Watt 5 Channel
Had a fright when I installed it, didn't work for all 4 channels. Discovered a loose RCA jack to my head unit. Then once that was solved all channels worked but any volume at all began a reverb. I adjusted the input gains and found the right level and it has been great since. Way more amp then I need in an extended cab truck, but now I only turn it up to 25% and am happy with the sound. Clean and crisp. I get some hiss if I switch to surround sound mode on my head unit, not sure why, but I rarely watch movies in my truck. So word to the wise, check your settings for HOW you are using it, 2 channel, 4 channel, 5 channel, High Power or Low Power inputs, full range or high pass/low pass filter. Mine came set for low pass, I switched to Full range 4 channel to match my head unit, adjusted the gain on the inputs, and even took it down a little farther after I got clear sound. I don't need to over drive the inputs since I have a WHOLE lot of amp in a truck. ** Update, Still loving it. I wanted to use the 5th channel to power my Center Channel from my Head-Unit (since I already have a powered Boss 10 inch subwoofer attached to my Head Unit subwoofer channel), but when I tried, the 5th channel still puts out a lot of bass and you lose the center channel frequencies. I am trying to find a good fit for a 2 channel amp for the center channel and I will add another 10 inch subwoofer to the 5th channel. Just want to fill that hollow sound area in the center of the vehicle. I am thinking a smaller boss Phantom 2 channel 1100 watt amp will do what I need. Needless to say, it is already a LOT of sound in a Toyota Tundra cab! I don't need it up loud, it sounds fantastic. ... show more

Mixed Bag Please Read.
Style: 3700 Watt 5 Channel
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. ... show more

There are a lot of things to like
Style: 3700 Watt 5 Channel
It seems like they thought of every possible installation situation with this amp, in addition to including a 5th channel.for a subwoofer. There are high and low impedance connections and many other adjustments. As far as power output, I have not had any problems powering my 5 3/4" speakers and tweeters in the front or the 5 3/4" and 4x6" pairs on the back channel. It is also powering my Fosgate 12" thin mount sub very well . I am getting exactly the clarity and volume that I wanted to be able to listen with all 4 truck windows down at highway speed. The lights are nice as well, but they will eventually be covered when I reinstall the rear bench seat. Seems like a well built frame and unit oveall. I don't really have any complaints assuming it lasts for a while. I definitely would NOT buy the copper coated aluminum boss wiring kit again though. Do yourself a favor and go with real copper wire. It's hard to belive that the Boss company that built this nice amp would agree to put their name on that embarrassing wire kit. ... show more
