Re: which wires to tap for sub and remote signal
You should tap into the rear speaker leads at the stock amp. And NO you wont need a line out converter, your amp accepts high level inputs.
I wired my JL 250/1 using a line out converter because the original amp i had in the car did not accept high level inputs. Regardless it worked out perfect and sounds great.
