Currently I've got 4 Pioneer speakers in my car(Toyota Camry). Two 6x9 in the back shelf and two 4" in the front doors.
The front door speakers are sounding kinda puny compared to the 6x9's, so I was hoping to switch those out for a new bigger 6.5".
Do I need to stay with the same brand of speakers to maintina SQ? What would happen if I put in Infinity Kappas in the front and leave my Pioneer's in the back?
