RCA's causing continues bass note until I unplug 1 wire...

I've heard of this problem before, but can't recall the solution. As soon as I turn the key the bass note starts playing non stop unless I unplug either one of the RCA jacks. Doesn't matter which, then it will function normally. What causes this?

Try a spare set of RCA cables. Might be a bad wire. Possibly a short in the RCA output on ththe deck. What brand of deck?
