Seen many posts on here but none that seemed to give specific info on aftermarket speakers for the rear oem 4x6's. I know a 4x6 will fit, but can you fit for example 6.5's with some modification? Looking to replace oem with components, and 6 3/4 or 6.5 look like the most widely offered. It would be nice if they could be made to fit. Not worried about having to cut anything, but I am interested in max allowable depth I will have to play with. I guess spacers could let the back end magnets fit into the door cavity right?

I think Memphis has a great set that fits perfectly.

I've got a set of 4x6 Infinity Kappa's in my truck. They rock!
