erm, I don't think there's anythign in the JL stable tat will match the stroker in SPL... you're looking at subs that can take 2000w without breaking a sweat.
cool subs, they are not severly underpowered.
Do not look at max handling.
I've Done A install for someone with strokers.
We put 900w rms on them(450w a peice) Strokers are a unigue design.
They hit 152.6db.(2 12"s)
you don't need 7 batteries or 3 amps.
if you want the best, put about 1000w rms a peice on them, but for being severly underpowered, that is bull ****, and you know it.
Quit bull s-ing with people, just cuz they aint seen the **** before.
