I have an old, but barely used JBL mono sub amp. Is has both right and left inputs and the JVC R900 head unit has both right and left outputs for the subwoofer. I only have a single RCA cable run under the carpet that is not used at this time. Is the subwoofer signal from the head unit a mono signal or do I have to have both sides hooked up? What about on the amp end?
