check all connections. and i mean ALL connections. amp to battery in the rear and the front. check your ground at all points.

and don't forget to double check the fuses and the sub! I hope you own a DMM (digital multi-meter)

yea i have a ddm the sub is deff at 2 ohm. ill have to check the fuses and the grounds. i assumed this is the problem that one of the grounds may have come loose or i did not tighten one down well enough. i was embarrassed every one was talking up my system for just being one 12 then it shut off.

Maybe a loose connection on the sub or a speaker wire grounding out some where. Like stated before check everywire!!! Let us know what happens.

Not enough amperage?

You would get a voltage drop then.

Hasn't been asked yet but does the amp ALWAYS go into protect every time it's turned on?

If so, disconnect the speaker wires and and turn it on, if still in protect I'd say something happened to the amp or maybe a loose speaker wire shorted causing damage to the amp.
