But 6x9s are just the shittest anyway. A good set of comps up the front, some mids in the rear for a bit of fill if you wish in the back, then a sub in the boot

ive already got 7x10's on the shelf mate, and an amp and sub in the boot, just wanted a bit more sound up front because the standard speakers get dround out by all the stuff being in the back.
