BOSS Audio Systems MC900B Amplifier for ATV UTV Car Marine - 500 High Output, 4 Channel, 2/4 Ohm, Bluetooth Multi-Function Remote, RCA Out, Weatherproof, Use Amp with Stereo and Subwoofer, Crossover

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.

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!!

Nice modern replacement for an old AM/Fm tape deck in my 1986 Harley Davidson. Fit in easily where the tape deck was originally installed with a little bit of creativity. I have it connected to a couple of Hogtunes speakers and I’m happy with how it sounds. Easily connect to my iPhone with Bluetooth and also keeps it charged with usb connection.

I picked this up on a black Friday deal last year for my 91 Corvette. I'm really impressed with this little unit. I'm running some mid range pioneer speakers and it's very loud. Loud enough that driving 80 with the top off and you can still hear it clearly. I'm also using a software EQ which helps a bunch. There is no built in fader as others have stated. But you can easily wire in a fader control for $12 or so. This unit supports 4 and 8 ohm speakers which is a nice feature. Overall I'm really happy with it. No idea on longevity yet.
