[QUOTE="theCybe, post: 1070183, member: 558105"] It's possible that the RCA is damaged; Connect the amp to a set of RCAs from elsewhere, and see. Maybe the pre-outs on the headunit are botched? It's unlikely that a sub will just 'stop working' completely; At least, not without an ugly plume of smoke and smell that sticks to your upholstery. Even if the subs were to have 'locked up,' it'd generally be noticable (ie, they wouldn't move when you pushed on 'em.) ---- Here's what we see; The amp isn't getting a signal. The signal comes from the headunit. So, either both this amp and the previous amp aren't working right, [unlikely] Or, the headunit isn't putting out a signal [possible] Or, the RCAs aren't transmitting a signal [possible] [/QUOTE]
