I'm still hoping someone uploads the wiring schematic used for the stock US hifi system... i just want to know what wires are (R- R+ and L- L+) for the sub outputs from the amp... that way i can tap a RCA line out converter or use high level inputs to add my own aftermarket amp and small sub... then just back down the bass for the stock speakers and have the real sub handling the low end load.. anyone have access to this by chance yet ?
