Hey all, just a few quick questions before I start a head unit install on my Impala. I picked up a Pioneer head unit, GMOS-04 wiring kit to retain onstar, chimes, and retained accessory power, and an ASWC-1 wiring kit to keep steering wheel controls. My plan was to install just an aftermarket head unit so that I'll have bluetooth and USB input, and leave the speakers stock since they sound decent. I then considered replacing the rear deck speakers, but a little research showed me that these are 2 ohm and are filtered for lows, so the set of 3-way 6x9's that I have laying around wouldn't sound very good with this factory amp setup. My question is this- can I run new speaker wires for only the rear channels directly from the head unit, like you would do in a non-amplified system? Would this cause any problems with the rest of the system? I don't understand how these factory amplified systems are wired, so I don't know if having those rear channel outputs not hooked up will cause any other problems. Any help would be appreciated!
