Aftermarket sub & amp with factory Mach HU

[PanamaVR4]

I did some searching but could not find exactly what I am looking for. I am looking for a wiring schema or some information that would allow me to pull signal from the factory sub wiring so that I can either convert (via line level) or wire directly into the aftermarket amp. I will be running separate power wire, but want to grab signal as easily as possible so I can convert back to stock when I sell the vehicle. Any help is GREATLY appreciated. Thanks!

The subwoofer plug has 10 pins, only 5 of them are used.
(Pin # - color - purpose)
1 - DG/VT - Subwoofer High Audio Mute(?)
2 - BK/LG - GROUND
3, 4, 5 - NOT USED
6 - LG/VT - Power (Hot all times from fuse #25)
7 - RD/BK - Subwoofer High Audio (-)
8 - BN/OG - Subwoofer High Audio (+)
9, 10 - NOT USED

So I take it the Subwoofer High Audio wires are speaker-level inputs for the amp? Which wire is the turn-on lead? I think those would be the only ones I need. All help is appreciated. Thanks!

They are speaker-level inputs from what I understand.

I ran new wires from the headunit when i put in an aftermarket amp and sub. You might can experiment with the factory amp wiring to get it working, but you'll probably have better results if you just run new wires.

get a new head unit anyways, its not going to sound good running of the factory unit.

Until I had the money for a HU, I ran an amp and sub off the factory wiring for a long time. It worked very well and I still have my amp and sub hooked up the same way with the aftermarket HU. We spliced into the stock speaker wires under the passenger kickpanel. My amp has a linelevel input, so we took both rear + and both rear - and put them into the amp. Like I said, it works very well with the stock HU or an aftermarket one. Sorry, but I don't have the correct colors available at this time.

did u say both rear + and rear - because i only found one after tearing apart my backseat... i found the 7 - RD/BK - Subwoofer High Audio (-)
8 - BN/OG - Subwoofer High Audio (+)
and spliced both of those and at this point am running them to a hi-low converter, at this point i have yet to tune the hi-low converter to see if thats what the problem is unless i spliced the two wrong wires

Hmmm, if you found the factory leads to the optional subwoofer amp, then there ya go; you can probably use those. Haven't worked with them though, so I dunno what to do. I spliced into the backseat speakers, that's why I used 4: 2 for each side. This way the sub hits whenever one or both of the rears hit.

The subwoofer outputs from the factory Mach HU are Line-Level outputs. The Speaker-Level outputs are coming out of the dedicated SW amp.
