My friend just bought an '06 WRX and wants to put in a new stereo. I'm putting in an Alpine head unit for her and was wondering if there were any factory external amps in the car that need to be bypassed or anything? I haven't even looked at it yet so I don't even know who makes the stereo. Also, is it going to be a ***** getting the stock head unit out? Does the consol that holds the head unit come out or what? I tried doing a short search, but didn't find much of anything that would help me. Thanks.
