Im trying to install an Alpine 9813 head unit in my 1995 Z28...I have it in and its getting power with the aftermarket wiring harness...but why arent i getting any sound out the speakers?

 

Im guessing there is an adapter to play an aftermarket head unit on my stock individually-amplified Bose speakers?




What if I just replaced the stock speakers with my aftermarket ones...will the problem go away?

 

you can try the IECPSI2 premium sound interface from installedge.com you can pick them up from bestbuy and other audio shops.
