you can either wait for JL to come out with something or talk to progressive audio in pearl city (being that you live in Hawaii too).

I get all my stuff from them.

I have a yellow X 2001 2X4
with
Kenwood CD.
Kenwood Passive Parametric EQ.
Two Kenwood 350 watt amps (for fronts and rears).
Kenwood 800watt (for subs).
Boston pro serious seperates for front.
Self installed Kappa 6.5's in the back two doors with boston pro series tweeters on the top of the door.
Alpine 6X9's in the rear (stock mount), hooked up to the deck.
Boston pro 10's with a custom box.

It's pretty damn loud and Progressive audio does a great job.
In fact I'm going to have the re-design a sub enclosure that has an amp rack mount inside the sub box. The you can pull the back seats down and the amps will show behind plexi glass or something like that. They can do a lot!!
their phone number is...

486-8847 and talk to Bill (tell him Keith sent you)
