Which wires to tap into

Which set of speaker wires would be best to tap into on the factory L7 amp to add an extra sub and amp?

You should find the user Technic on this site. He custom makes harnesses that negate the need to tap into things.

I know, I had been bugging him about a harness but he was out of stock.

I got restless and just spliced the LOC into one of the subwoofer wires. I temp installed the remote wire by just jumpering it to the power with a 4A CB in between.

I heard that there is a relay of some sort that you can use to amplify the signal of a speaker wire to use as the remote. Does anyone know anything about that? That way I'd be able to get rid of the CB.
