Well today i installed everything the concept amp and the SX 15. well about an hour ago. i turned on the car and no sound then changed cd. and nottin then i hear a BOOM BOOM BOOM BOOM and look on the side of the amp and it shows cliping. and its going hard to where my lights dim crazy. the sub is a 2ohm sub i wired down to 1ohm for 1200 watts. what could be the problem the RCA's worked this mornign when i had my 500 watt amp. THANKS ALOT.

IT shows clipping even with the sub making no sound?

no only when the sub hits. it shows clipping on the amp. when i had my 50 cent cd in many men it didnt make any sound then i hear boom boom boom boom boom. and then i notice that hte light on the amp says cliping.

Does it do this with any volume level?

mope voleuime level was at 0
