RCA problem

[terra 5,000+ posts]

I was driving down the road today and the sub just stopped playing. so i pull over and check it out. everything is still firmly connected. the amp is on and looks fine, just the analog needles arent moving at all. so i figure its the signal from the deck. I switched the rca's with the speaker amp rca's and still nothing. Switched it from the sub-outs to the rear amp preouts and still nothing. So im assuming it has something to do with the rca's near the amp or even the amp itself. any ideas?

Try wiggling the connections while playing music?

i actually cant figure this shit out. the amp registers no signal. can i use a dmm on the rca outputs from the deck to figure out if im getting any signal?

Absolutely. That should be the next thing to try. Set the meter to AC, not DC.

Thats exactly what was going on with my old Pioneer. Ended up having to get a new deck and was told the preouts on the deck were gone. Wth me it was only the front and rears that did it while the subwoofer out played fine.
