I have tried the alpine wireharness that just plugs into the stock wireharness and then into the aftermarket deck, I got no sound from this I was wondering If i unplug the stock speakers in the doors and plug in my mb quart speakers will I get sound from them.

 

what type of system is your stock system? monsoon? did you hookup the remote turnon? (blue w/ white wire) if not try that.

 

I got the three speaker bose

 

you may need the premium sound interface box that gets hooked up between the deck and the car's harness to interface with the bose system. you can pick that adapter up at best buy or other audio shops. or you may have to run new speaker wires and replace the speakers.
