BOSS Audio SystemsPF1800 4 Channel Car Amplifier - 1800 Watts, Full Range, Class A-B, 2-4 Ohm Stable, Mosfet Power Supply, Bridgeable

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!

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.

This thing pounds

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 amp is doing good so far.. I installed it 9/23/24 and so far these two days it’s been performing great. I’m running 2) alpines 6x9’s, 2) alpine type r tweeters & 1) alpine type s 12” sub and bumping without any issues.I’ll post the date if I happen to run in to any issues so far but m happy to be bumping it in my garage 😆🔉🫨
