I'm running a 12" JL Audio 12w3D4 off a fosgate 800.2 amp wired at 2 ohms on the speaker and the amp is brided mono. it's probably putting out around 1600 watts of power. It was hitting 2 15" fosgate dual voice coil subs before running each at 8 ohm but then run down to 4 ohm before getting to the amp.

The JL hits cleaner than the 2 15s and the bass is plenty. the amp's gain is not set very high, maybe halfway if that.

It has a 2.5 farad capacitor and 4 guage cable to the amp.

I alwasy run the thickest gauge cable I can.

As far as the amp shutting off, it is probably going into a protection mode. if you turn off the car and restart does the amp come back on and then play for a little while?

I would check the woofer wiring, and make sure you are not overloading the amp. if the ohms you have with the subs wiring is 1 ohm or 2 ohm, you need to try to wire them at 4 ohm and see if it makes a difference on the amp.

Not many amps are stable at 1 or 2 ohms.
