I've got 2 Hollywood Expeditions (12's) in my trunk, sealed box and my own damping matting throughout the trunk. I'm going to be rewiring my entire system in the next few weeks so I'll take pics of the process and the installation of my new L7 sub.

As for your question BENZ, about what to put in your doors and front, I'd suggest you put some 2 channel Infinity's in there....great, sharp response and chrisp hi's, plus they're effective and won't break your bank.
