I loved all the JBL woofers I have owned. I ran a pair of 12's at one point and 4 10's at another point.

But they generally, price wise, are more of an SQ woofer, in my experience.

Nothing wrong with that , but it depends on your tastes

 

if you want to run street B this year i have a great pair of subs for sale.. they are shocker3 12's. they are just one model down from the sig series. great woofers. my friend swaped these in his car just before finals and he gained 6 db. he was using H2's before the shockers... LMK
