A:AnswerHi bigeasy, the setup you have in mind is not guaranteed to work. The USB port of this turntable is designed mainly to establish a connection with a computer. We recommend checking with a professional installer for car stereo options that will work with your vehicle. Thanks, -Mark
A:AnswerProvided you have a pre-amp (>$20) and the soundbar has phono input (red and white sockets-some do, some dont) internal amplification(it does) , it should work out of the box. If not you will need a few small adapters. (ex phono to 3.5mm ).

A:AnswerWe have the speakers connected directly to the turntable without an amp, no problem; the speakers are powered. Not sure what might be going on for you, but good luck!
A:AnswerRCA jack's only. You could try hooking the turntable to a computer using the USB cable, then output the computer to the Bose system through HDMI.
