stock stereo switch?

Yes, there is a interface that can be hooked up for aftermarket hu's with a remote. I believe grandprixstore has them with a list of hu's they're compatible with. And with an aftermarket deck and EQ, you can get a way better sound. If you want a little more punch from the 6X9's, get the baffle covers that go under them. Kinda puts them in a small enclosure. I beleive the other rear deck speakers are 4", but don't hold me to that. I haven't looked at them in a while.
