RCA cables like these can be brought from any electronic shop, no special rca cables are required ..
you do mean RCA right ?? this is what is looks like (below),, and can be brought from any electronic shop.its the same kind used to connect your dvd player to your tv. BTW these cables are only necessary when connection to an amplifier. other than that,, you have all ther wires you need on the unit, 2 power and 8 speaker wires. yellow is connected to the battery, red to the battery or ignition, black is the ground, and the pair colored wires are connected to the speakers. The unit ships with these wires so there is no need to buy them seperately. If you seek an adapter to convert the units electrical to your vehicles electrical you will not find it, It has to be connected via the wires. Simply clip the wires out of the old units adapter.
