Well, that's a good question.

From the reading I've done, only the FRONT DOORS have full range sound fed to them (20-20khz), this is downstream of the amp. So you should be OK tapping into them at the amp location.


The instructions that come with my JBL MS8 (basically a LOC & Sound processor) say that to tie in to systems with factory amps and subwoofer, all three (front doors and sub) channels must feed the line in signals.

I'm going to try the front L-R wires right at the deck, as that's where the PAC Audio LOC harness's take off from. To make things easier for trial and error, I got a bunch of spade connectors like these:

and made up a harness for the MS8 so I can plug directly in to the wires and when I cut wires that I shouldn't have, I can just plug these back in, without having to solder and tape.

You can get fully insulated Male and Female ones at most auto parts stores.
