    1993 318i aftermarket head unit turns on but no audio ##NO STOCK AMP##

    Hi everybody

    I just replaced my old Blaupunkt Boston CC22 for an Alpine CDA9827RR I had lying around. The unit turns on but no sound comes out of the speakers. It seems this topic has been extensively discussed before, but the issue here is my car doesn't have a stock amp, so the blue wire splice won't solve my problem.... any hint?

    Thanks.

    Solved. The new head unit was pre-set to send audio to preamp RCAs instead of speaker lines.
