  • Class A/B Topology - Class A amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class B amplifiers have no current flowing through its outputs with no audio signal
  • Full Range - With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers
  • MOSFET Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry
  • Variable Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
  • Low/High Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
  • Variable Bass Boost - With Variable Bass Boost you have the control of exactly how much BASS you want to pump out to your subwoofer(s)
  • Bridgeable - Dramatically increase the power output to you speakers and subwoofers by connecting two amplifier channels
  • Dimensions - 17 x 10.31 x 2.25 - 4.9 lbs.

GOOD AMPQuality AMP & should get 5 star reviews across the board I have read the negative reviews but that's mainly DUE to the AMP being wrongfully Installed or not HOOKED UP Right. Being in the Car Audio Field for over 20+ years & just recently opened my OWN Car Audio SHOP back in JUNE of this year. THIS AMP is WORTH EVERY PENNY I just Recently Hooked up a Audio system in my Daughters SUV 4 Door Speakers with Tweeters & 2 10" SUB's & the system's SUBS HIT VERY WELL along with Quality beat & sounds. MY Daughter said her system is performing VERY WELL above her expectations since the Install July 4th Holiday Weekend. & she said the LED's on the AMP is a nice touch & nighttime Glow inside the SUV.... AS long AS THIS AMP IS PROPERLY INSTALLED BY SOMEONE THAT KNOWS WHAT THERE DOING & HAS BEEN IN THE CAR AUDIO FIELD FOR A WILE THIS AMP WILL OFFER YEARS OF TROUBLE FREE OPERATION.5Couldn't use this productI was pretty unhappy with this product. First of all, the screw/caps that are used to secure your cables can be small and creates a problem when you're trying to make a solid and secure connection. Two of them ended creating stripped threads, and would not tighten into the amp anymore, would just continue to spin as you tried to tighten it down. Then the reason I had to return the product at the end of the day was that my audio would randomly shut off on long drives, and then resetting the headunit during the drive brought the sound back, but it shut off pretty quickly. I assumed it might be overheating and I believe I was right. I returned the product and purchased a Pioneer 5Channel and haven't had a single issue with the Pioneer so far, so clearly the Boss Amp was having issues. Would not recommend this unit. I would push for you to get the Pioneer 5Channel which is around $220.1It's stupid loud, which is what my teenagers wantedThis amp freakin rocks! I have it in a Toyota camry, and it's pushing 6.5" front speakers, 6x9" rear speakers and a 12" sub, and it's never come even close to overheating or cutting out. It's stupid loud, which is what my teenagers wanted. Fairly easy to install and telephone tech support was quick and helpful in matching up all the channels with the right speaker wires once everything was wired. Would buy this brand again.5Four channels for highs/mids sound great. LoudFour channels for highs/mids sound great. Loud, nice clarity, zero distortion. Fifth channel for the sub is almost none existent. Only know its working by actually putting my hand on the sub(s). Barely even moves my one 12" Pioneer or either of my two 12" Orion Xtrs, which is disappointing. (I tried with the Orions just to make sure it wasn't the Pioneer sub). This is in my beater car so overall happy with my purchase for the price I paid. Just was hoping for a bit more boom from the sub channel. It could be possible I have a setting wrong on the 5th channel, but doubtful.3PassAmp often shuts off when really pushed but at reasonable volumes it's great. Slight alternator whine even with a solid ground and a noise filter which appeared after a couple months. Only noticeable at minimum volumes though.Update: Solved alternator whine by turning the gain way down but still had shutdown issues. Finally it will only power for a few seconds with no speakers connected at all. Didn't even get a year from it and never used it on speakers bigger than 4 X 6.5s.1Nice quality.I have 2 1200 watt subwoofers, 2 450 watt 6x9 speakers, and 2 200 watt tweeters hooked up to this amp. All speakers are putting out their full rating and there is no sound distortion. I still have another 2 6x6 speakers and 2 more tweeters to install, this amp should be able to handle them all. Definately a good value.5Defective productI wanted to really like this. And I wanted to run 4 speakers in my Ram 1500! But after my install, with channel 1, the front speaker was filled with static. I swapped speaker terminals and still had static in a front speaker. I tried other speakers and got the same results with channel 1. So I m Returning this amp. I picked up a kicker amp and I have no issues with the amp so far. All 4 speakers sound perfect with plenty of punch behind them!1If you install it right you'll love it!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!5Almost for 3yrsWorking fine at first, but it seems to run hot (and I am just entering my vehicle and maybe in it for 30mins) and the protection is too sensitive. I either have the volume down on the amp itself and try to listen at a decent volume and since it's hot where I live now (summer time) I can hear my A/C over it. I turn up the volume on the amp and the protection pops on at vol lv 15, and it's not even loud. I understand there is a difference with current music and the older (back in the day) music. The recording was different, better equipment now. In other words, older music you may have to turn it up a little more. But that's not my case! I had a Rockford Fosgate that gave no probs...going back to!1Aloha Kickin!!!!!I had this amp installed here in Hawaii. Its pushing 4 alpine 6.5s with tweeters and a 10 inch kicker like a dream. The tech says it was more than enough to push two 10s. All this in a Nissan Versa Note. No boring days in traffic anymore 5
