My passenger side mid bass blew. As much as I would like to do a full audio sysem in their I don't have the money. I would like to put the infinity Kappas in their but they are 5 1/4 and apparetnly it takes a 5x7. Anyone know if the 5 1/4 will fit? I might be willing to spring for a 2 channle amp if need be to power the speakers... any other suggestions?
