When I bought my 95 the Bose system had been took out. In fact there wasn't a radio or speakers in the car. It apparently had the 5 speaker Bose system in it at one time. I bought a pioneer stereo and some speakers to go in it. The stereo went in fine. Everything working on it. I bought a clip for the radio to hook it up. But when installing speakers...no sound comes out of front or back. All wires are connected....what could be the problem? All replacement parts are brand new.

 

Since you don't know what the previous owned did, you are going to have to check all the wiring. I replaced everything with a bigger gauge wire when I ditched my Bose setup.

 

I could be wrong ....but I think you have to have a different wire harness for the bose system ??
Slide the radio out and connect a speaker directly to the harness on the radio ("not the harness that came with the installation kit " the bose system my have a internal/inline amp
that is blown ??
