The more I google & read the more my head hurts!
Decided I want to completely bypass the OE amp.
But all this mess of a bypass harness is too much...why can't I just unplug it all at this OE amp?
Then could I do this???
Wire my new head unit's wires (pwr, acc, grd & dash lights) to factory harness (& not connect the speaker to factory harness). Use the RCA connections & head units remote wire to go to a new amp (for door speakers). Then add length to OE door speaker wires to get to new amp.
This is why I like working on my '72 much better
