I recently hooked up my Amp and went to test it tonight with a old sub I have. I know the sub works because we tested it on another amp this week.
Amp turns on, but no sound from the sub. Checked the amp ground, power and remote power, all good.
I have a double din with a dedicated sub in, I put one of the RCAs (white) in there and plugged into the amp, tried a y cable both from the amp and HU and still no sound.
So I was thinking it has to be a bad amp, or a bad RCA cable? Also, if the ground was bad would the amp still turn on?
