the amp is turned all the way down by the way hahaha and im in the prosess of building a box for it 4 12's 2200 watts

WEAK!!!!!!!!!!!!!!!
i saw no vibration and heard a lot of rattling. the two 80 dollar 12" sony xplods i got from wal-mart pack more punch than that.
but congratulations, you successfully hooked up a "system". thats a 73 burban? that thing is one big airbox; you could have gotten more bass from two 100 watt 8"s. sad, really sad. my advice is either is you either buy some better subs, learn the "theile parameters" (like I do), or pay someone else to hook it up.
