Hey man, I can really guide you if want. I've had several buddies that have crown vics, one of them had a BTL 18 in the trunk. Hit me up tonight if you can.

I'd prefer a ported but the diminesions I gave are the same as the box I have now for just a couple cvx 15s

Hey man I'd appreciate any help!! I've built a couple generic boxes for buddies but nothing crazy and want this system to sound awesome as it will be my daily with a few comps setup! I've been all over the Internet and can barely find anything worth my time cause I don't know a whole lot yet, this sp4 will be my second system...
