you need to do a complete bypass of the amp and run to the speakers direct using the head unit or prefer a 4 ch amp.

try to find a way you can feed the low level rca and splice into the stock amp and keep it since it is a decent setup unless you willing to pour some good money for speakers, amps, tweets and labor

so pretty much the easiest way would be to run an aftermarket cd player and amp. why cant you just swap the factory speakers with aftermarket ones

things to understand...the hk system in those vehicles is designed to function as is....replacing speakers unless adding aftermarket amplification is going to sound like ass especially if your are simply replacing the mids up front. Speaker impedance needs to remain the same with the aftermarket speakers if retaining the factory amplifier....only drop in speakers that exist for this situation are the kits from bavarian soundworks
