Thanks so far zzzzzzzzz!!!
I think I'm on board with the 2 ohm thing as well. Just can't find a friggin nice ole school 4 channel Rodek!!!!

Might go old school soundstream though. The current location of the 5.25's does sounds quite nice, you're right. I've got 4-10" JL's and I'm going to be removing the firewall where the ski bag pass through is just like you've mentioned for sure. I haven't decided on the arranagement of the subs yet though... Still trying to work that out as well.
I'm running just 2 of the 10's right now. Just thought I would have to do something else up front when I get the other 2-10's installed.
