Have you tried disconnecting the signal cable?

Their powered subs are pure junk and you may as well have thrown it out, feel lucky it lasted this long.

It's probably another one of these situations:

JBL PB12 subwoofer, Class D amp, dead.

is there a simple way to replace this amp? i mean, is soldering needed, or can i just screw a new one in? to my understanding, these jbl amps are junk. is there an alternative amp that i could use for this woofer? i would really like to get this thing working. thanks
