im Looking for some decent cheap replacement 8inch drivers for my Mustang. they have 8inch subs from factory . Im not necessarily looking to buy "subs" as im running a low power system and the subs in the doors now get too muddy

I think I can get away with some more efficient drivers

must be 2 ohm or dual 4
must not require lots of power
must be less than 3 1/2 inches mount depth

also consider some 6inch drives..subs or woofs / mids ...it might be easier to get some 6 inchers and make an adapter to go from 8 to 6 .
