hey TampaBayLightning,
is the a port tube i see on the thunderform box? I have the thunderfroms too but have no port tubes.

 

I tell ya what, no matter what you listen to, some Rockford Fosgate DVC HX2 tens will slam for ya! I've got a 97 reg cab with two HX2 10's running off a Rockford Fosgate 500a amp. The system flat out booms, to both rock and rap. As for the box, Ive got two separate slim, Q logic boxes. They work, but take away a bunch of leg room. I'm only 5'9" but my taller friends always complain. It's worth the extra $ to get a custom box to fit whatever you get! That'll be one of my next purchases. Good luck, and happy hunting!
