Fantastic way to simplify your sound system if you use your phone for music!
Easy to install, all clearly labeled. Excellent sound quality, small in size, easy to place in a hidden area, and the controller has a nice long cord so you can place it anywhere you want. The bluetooth connection is seamless and connects almost instantly. It’s an excellent value for the price, i haven’t bought a radio or amplifier that i have liked more. I use it with an iPad that i use for my radio and it charges it seamlessly. The USB cord only charges though so keep that in mind, its bluetooth only, but like I said it’s a nearly perfect bluetooth connection. It will also run a separate amplifier for a subwoofer or whatever you want. It’s a fantastic Amplifier with a great sound output and good volume control. No radio needed!!

Installed in classic car with radio delete.
I bought this amplifier because i wanted to play music but did not want a complete radio system as car is build for street and strip. This Bluetooth amp was what i needed. i installed a radio delete plate in the factory location as this is where i will mount accessory switches (electric fans and fuel pump) and start button. This unit is small enough to hide anywhere under the dash or in glove box. The sound is excellent for its size. I have it hooked up to a pair of 6.5" Rockford Forsgate P1650 speakers for the rear and the center dash speaker is the Retro Sounds dual voice cone speaker and all sounds very well - loud enough too. i play music from my iPhone. What i wish it had was an app to allow adjustments to front and rear or left to right but it truly isn't necessary as it sounds fine the way it is. What i also wish it had was a built in mic so i could answer calls and hear calls over the car speakers. For the money spent and to have very good sound in the car, this was a great option. Now, i hope it lasts. follow the instructions to the letter and make sure you have a good ground. When wiring speakers it is important to wire them correctly + / - terminals must be correct. take your time.

Don’t buy, complete junk!
I bought this amp to use on my Harley. I hooked it up to the factory radio and aftermarket speakers. It sounded better than the factory stereo but sounded like crap above halfway. So I ordered the boss elite head unit that’s rated at 50x4 and was gonna use the amp with that since it was rated for almost double the wattage. I hooked up the head unit to the amp and was not impressed with how loud it wasn’t. I disconnected the amp and just hooked up the head unit and I believe the head unit was louder by itself. This amp definitely does not put out 90 watts x 4!

great but short life
First off, this does nearly exactly what I wanted it to. I put this in my classic car and able to leave the non-functioning stock radio in the dash for a period look. Issues I have with it. no physical power switch without using the remote. When I first installed it (without the remote), it powered on instantly. With no immediate volume control or power switch I was unable to turn it off unless I turned the car off or fumbled for my phone to turn the volume all the way down. I later installed the remote and that helps. I also installed an inline power switch. The biggest problem I had was within 5 weeks of installation it stopped powering on. It was about 70 days, and the Amazon return window was 60 days. I contacted BOSS directly and they were great to work with. After determining it was indeed faulty they sent me a replacement. I need to install it still. Hopefully it will last longer than 5 weeks this time.

Bluetooth connects instantly!!
Kubota XG850 This is the easiest, fastest, cleanest install ever. Works perfectly and sounds pretty good. It's only been a couple weeks hopefully it stays working this good. All parts seem to be good quality.
