I tapped into the rear speaker wiring at the left drivers side Kick panel .
Spent more for the LOC too ..
There is also the option to wire staight to an Amp that accepts High Signals ..Depends upon the Amp and IT's capabilities and signal to noise .

I ran a loc ran from the same as brian. Worked great for me. Ran wires all the way to the trunk and hid the loc in there instead of the fatter rca wires.
