Currently, I have a new double din head unit hooked up to my sc3 via speakers wires off of the rear factory amp. I cut out the wires from the amplifier that belongs to the each speaker inside the car, and hooked it up directly to the speaker wires of the new head unit's wire harness. Now my question is, if I decide to add a sub woofer, can I actually plug in an amplifier using the RCA outputs of the new head unit? Don't forget, the speaker lines from the new unit's wire harness is already being used. I just want to plug in a 20ft RCA cable to the rear speaker output channel of the new deck.
