Ok i just got done with my box and every thing and got it all hooked up and i got wire to 2ohm and when i first listen to it they pound hard as hell and then after like 5 minutes not even at half volume my amp over heats then comes back and then shuts off again after another 5 minutes and its pissed me off my amp is a A8000t and its air cooled my piece of sh*t sony never over heated like this, what is wrong?
