THIS. Its all good, a learning process. Its good to start with audio, nothing TOO major can go wrong. Make sure you disconnect your battery before starting. Basically, instead of using the rear/front left/right outs on the deck, you use the RCA output, and that sends audio data to your amp. From the amp, you run speaker cable (left/right front/rear) from the amp to the speakers. So the direction of audio flow goes: HEAD UNIT > AMP > SPEAKERS. Again, let me know if that doesnt make any sense :P Alf
