Shark 1400 Watt 4 Stereo Waterproof Amp Channel Motorcycle Boat Snowmobile Audio System, Waterproof Turbo Style Speakers (Subwoofer Output), LCD Display, Wired & Wireless Remote, Model Shk8300, Black

Poor sound quality. There is a constant buzzing noise when you have it in Bluetooth mode. The unit has a spot for a subwoofer but I have searched high and low and can t find one any where. Also the connectors make it impossible to use other speakers. Move on an spend a little more money on a good system. I will be.

This is a piece of junk. I ordered 2 of them Amazon replace the first one because shark does not respond to emails or phone calls. Amazon will not replace this one because it is outside there window. So do not buy these piece of crap shark radios.

It works very well but then gets hot and starts to skip.
