Me too....I have the F700BT and installed in my Envoy and sound only comes out the front. Do you think this is the same issue? It's weird because my aftermarket stereo hareness had the rca plugs which I plugged into the ones that came with the stereo and the sound would only come out the front speakers. Then someone told me to get the adaptors that you hook up the speaker wires to this new piece and then plug in the RCA's to this adaptor...Basically how do I fix this issue? The sound is only coming out the front and as you turn up the volume, it goes in and out...HELP!!! Thanks!!
