sub amp issues

[SmAcKpOo]

i have a rockford 351M powering 2 10" typeR's and recently the amp just shut off and i lost all sub channels. so i took a look at the amp, and it only powers up when the ground isnt attached, obviously i get no bass anyway..

so i leave the car on, unplug the ground, and the LED on the amp lights up, but when i plug the ground in, the amp goes completely dead. what could be wrong? blown amp? i checked all the connections to the ground and they are fine

send it away on warranty, and then sell it as new, because Rockford amps are garbage and this is not the last time you will have problems with this amp if you keep it. buy an older Phoenix Gold, Alpine, or older Rockford (with the square heatsink, because these ones are not cheapy pieces of junk like the new ones).

ya ive concluded that the amp is fried. im not sure if its still on warranty tho
