I picked up a GMC Sierra extended cab, and it's sounded awful. I knew the front door speakers were blown, so I purchased some Alpine S-S65's and installed those into the front doors.
The rear door speakers sound terrible yet, and i'm looking for something to replace them as well. I don't know much about the stock system. I've been hearing that the head unit has to be able to drive the speakers and not sure about any of this really.
I want to keep the stock console of the truck intact, and don't want to fill up my backseats with subs or anything like that. Any ideas for me? recommendations on speakers are a bonus!
