So I went thru the common trouble shooting tips.
The amp powers on, voltage looks good at 14v with car on.
I am using signal sensing.
I measure the voltage from the speaker terminals and it normally works for a bit soon as I turn it on and after a little but usually less than a minute the sub no longer works but the amp still has power. I get the same behavior when I hook it up to the sub, it works for a bit and then no longer works. While driving it works intermittently.
I thought it may be something to do with the rca cables or the tap from the speaker wires, so I grabbed my iphone and plugged a 3.5mm to RCA and plugged it directly to the amp still did not work.
I opened up the amp and do not see any burn resistors or blown capacitors.
I know this is an old amp, just not sure if I should give up and buy a new amp or if this one can be saved. Any help appreciated.
