Id say go for the l7. If you want sq go for a 10"L7 in a sealed box running a 300watt amp or if you want SPL go for a 15" L7 on over 1200watts on a good deck... check my photo gallery

. If your on a budget though I'd recommend a 12" Alpine type R on an alpine m-m500... a pretty good setup as well. Cheers.
