Typically, when a cap goes bad, it still allows power through, just doesn't retain a charge.

I think your on the right track, just start eliminating variables, like removing the cap. Then try the speaker.


With electrical components, anything can go bad, so dont overlook anything.

Figured it out rca wires messed up some how there less than year old to weird but cheaper than amp

Glad it was a cheap fix.
