you cant cut a piece of MDF to mount the speaker to? just use the existing hole for the magnet? custom door panels? you could do rockford 4" T142 coaxels in the doors then do 6.5 components in the back and in some qlogic kick panels.... that would be a really good set up...

i will agree MB quarts did go down in Q a little but are still good speakers... i personally wouldnt buy them anymore... diamond hertz and eclipse are my favs RF speakers are great too i have recently heard the punch components and they sounded great amp'd... those 6 speakers amp'd with those kicker 15s will be loud as f---
