enclosure: probably 1.5 cu.ft. sealed per sub. keep it chambered.
bridge the amp so it runs at 4 ohms mono, but be sure of the impedence of the woofers so as to prevent your amp from blowing.
best bet, take it to best buy. $70 for an amp install and they do it right cuz they are MECP certified.

i used to have it wired bridged to my fosgate dvc 12's were it would only be 1ohm at first I didn't know your not supposed to do that until the paper got seperated from the plastic part part on one woofer but it pounded hella hard. now I have it wired into 4ohm but it doesnt pound as hard it still pounds but not as much before it used to shake me and my navigator now it just shakes my navi you can still feel it though.

when you turn it up to high on the stereo some of the bass lines cut out?

Most amps have auto-protect circuitry.  Your amp could be temporarily shutting off to prevent damage if the load becomes too much.  Try turning down the gain on the amp, and/or on the signal from the HU

I was refering to the gains coming from the Headunit (gains=input signal, ohms=output signal).  If the input signal becomes too high, some amps shutdown.  How hot is the amp getting when it shuts down?  This could also be a cause.  Do you lose bass at the same place, in the same song, every time?  Or does it happen randomly?
