CVR's need a BIG box when ported... CVX's, not so big.

IMO, with that power, CVX's ported > CVR's ported... if you're going willing to spend the $ for a new custom box and new subs.

well if a ported box requires 2X the volume I doubt Its gonna fit under the rear seat. I think CVX in a sealed box would be better in my situation since I dont really have much room to work with.
