12-02-2008, 06:59 PM
Just bought a first generation 18" FI BTL dual 2 fully loaded, off of cobra65427289 ...never seen power....

Anyway anyone want to help me out with some box designs...I'm going to be running it off of a Fusion NV2500...Rated at ~1800rms but a few people benched them at around 2200rms...

I have an Expedition and took the third row out so i have plenty of space to work with...any suggestions?

ps. I already tried the RE calculator, but i keep hearing that it isn't that accurate...
