I want to modify the system connector that comes with the unit to grab the head unit signal from under the seats. Which pins serve as the inputs and which as the outputs? Also, when tapping the Stereo head unit signal from under the seats, should all four wires on each side be fed as inputs to the PP-82DSP? Thanks.

I'm wanting to know the same thing. Did you ever find out?

From what I have read
Two wires are from the head unit and two run to the door speaker as Inputs as do the rears if you want to amp them.
(on the 4 wire post 9/09 cars.)(pre 9/09 only have 2 wires at the
under seat connector the parallel connection between the under seats
and doors is in he kick panel in those cars)
The two from the Head unit must be extended and run to the 82dsp
one set on each side of the car .
Does anybody know the color code for the wires that come from the head
unit and the color code for the doors?
One way to determine this would be to note the speaker wire
color in the doors when installing new speakers and ohm them
out to the under seat connector as verification.
The inputs to the 82dsp should be documented in the manual.
Guess they don't label channels abcd to well.
You need a full pinout of that main connector .
Looks like the manual is dumbed down for use with
a factory car specific connector.
Or specific aftermarket harness.

There is only one lead from each side and that is what is needed for input.

Since they label channels alphabetically
Does FR= channel a Fl =b RR=C and RL=D

also thanks for the pinout

one wire for Input ? or both sides of the speaker
out from the head unit. Maybe I am confusing one wire
with both the +/- running in it.
There are both Input + and - indicated on the connector.

Cool, thank you!

So just to be clear, the fused yellow 12v wire and the black ground wire are not needed??? I only need those two underseat full range inputs?

Obviously the unit will by powered off of the battery, and grounded to the chassis.

You can match it up with the harness to what's shown on the amp.

One lead (pair of wires) from each side.

Correct. I don't recall when they became not needed but we were selling/installing these for over 2 years and we were connecting them every time. lol
