Review: 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.
Review: 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!!
