Does the Bose allow for any inputs in the back? Could I hook up an MP3 player?

 

Yes there are inputs, but they are utilized for the cd changer. If u are not using a changer then it is possible. The radio is made by clarion, and better car audio dealers can help with this issue. The problem lies in a proper way to fake the radio out and make it appear to have a changer hooked up. I'm still working on this.
