If you want your speakers to run off an amp, dont cut the factory wires. All you need to do is disconnect the harness. After being disconnected, run speaker wires from each speakers to the amp. I have dont done this before, but I would imagine that you would just need to plug in the LOC into the factory wires.
From what it seems, the signal would travel through the factory deck, through the factory speaker wires, through the LOC into the amp then into the speakers. The speakers would be powered from amp.
