1994 HOLDEN VR CAPRICE stock cd player, car you hook rca cables to it?
No, It won't accept them. If you are wiring in a Sub do a search on the forum I am pretty sure there is a thread on it.
ASR can modify your head unit to use RCA's, look him up, he is a sponsor on here. Otherwise get your self an amp with low level input's, basically you hook your speaker wires up to the amp and that acts like RCA's
