Adding Amps to Factory Nav
I have the factory NAV unit. I would like to add a 4 channel amp to drive the factory door speakers, and a mono amp to drive a JL sub.
What I am looking for is a wiring harness that plugs inline with the factory harness (I assume at the factory amps) that would easily allow me to wire to a LC6i, as well as the speaker leads back to the factory wiring so I don't have to run new wires into each door.
My 4 channel is an older amp, but has always sounded great - but not a ton of power, so I don't think using the factory speaker wires will be an issue.
I can/could tap into the factory wires, but would prefer to use a pre-made harness to make life easy if one is available.
Any suggestions, and/or wiring photos are appreciated.
