So I am going to be adding a JL Audio 1000/1 amp and 13W7 subwoofer in the back of my lade, just wanted to see how you guys would hook this up. The amp accepts high level as well as low level inputs, so would you just tap into the positive and negative going to the factory sub and run them to the inputs of the amp? Next, the amp as has signal sensing capabilities so you don't need a remote turn on wire, which is cool but does the factory wiring have a remote turn-on lead somewhere in case I wanted to use it, I'd feel safer using that, this way I know the amp isn't being drained when not in use. Thanks for your input!
