question, if i were to install a LOC to a car with a stock amp, but i was leaving the stock amp for the speakers, and just adding a sub\amp setup, would i splice the LOC to the INPUT wires (2 sets for front\rear) - basically the RCA inputs to the stock amp?
i think by looking at the harness\wiring diagram for that car, and the harness that goes into the amp i can figure what wire are input and what wires are output\power.
but is this how i could add an amp without adding a head unit or a crazy expensive harness?
