I'd like some good rear speakers to try to get my MJ's stereo to sound better. Currently I have some Polk 6.5" coaxial in the doors, I don't know what's actually installed in the back but they don't seem too awesome. I'm guessing they're low end Alpine to match what was in the doors.
I'm lead to believe that 6x9s will fit with minimal issues?
What's a good quality and intelligent choice speaker for the rear?
Ideally I'd like to get a bit more bass out of the system.
