Make sure everything is hooked up properly.. also make sure you have a solid ground...
I suspect, you had the amp bridged running the sub... amp pulls big power, and cutts out because of voltage drop, due to a bad ground..
running one channel, the amp is putting out much less power and everything is OK...
what is the impedance of the sub ? (what ohm?)

If you have a volt meter measure the voltage at the batery terminals with the car off, then again with the car on. Repeat at the amplifier.
What are your results?
It could be that your alternator is faulty and having problems keeping up with recharging the battery and running the system.
