I just bought my 2009 Malibu LTZ 3 days ago and I am very excited to be the owner of a Malibu. Unfortunately the rear speakers are blown. I have replaced many car audio systems in my lifetime so I thought it would be no big deal. At the time, I didn't know about the complications of a new car with a premium audio system. I could just replace the speakers. I found them online for about $40 each at gmpartsdirect. I would much rather spend the money on some Infinity Kappas instead but I worry that the speakers have four incoming wires instead of the typical two. I don't want to bypass the amp if I install new rear speakers because I think it would be difficult to find an amp to install in that little bracket. Additionally, I wanted to put an Aftermarket headunit in but I am afraid of losing my steering wheel controls and losing the boost from the amplifier. Any suggestions?
