i got my system installed today.... JL audio e1200 amp (200x1 @2ohms) and a JL 10w3d4 (250 watts rms)... i notice that after the first maybe 10 mins of running at mid volume my bass shuts right off and the red light on the amp comes on.. i felt the amp and it's hot as shiz.... is this amp just crap or could there be some other problem???
