I've done 4 jl 6w0's in several trucks, as well as 2 6w0's in several roadster convertibles (TT's, MR2's, etc.) and they can sound very good. Will it replicate the sound of a couple 12's? No. But they can sound atleast as good as a pair of 10's. They'll surprise you, that's for sure. The key ofcourse (as always) is in the install and tuning.
