Best way to wire subs to stock head unit?

[99Tahoe350]

Im not tryna do a serious system or spend a ton of money, but I got a single 12in JL sub and amp I wanna add to my 1999 Tahoe to get a lil bump.

I want to keep the stock head unit, so whats the easiest way to wire it up?

use line out converter so you can get a decent amp for the sub. and hook it up.

I use my stock radio with my setup. I have a 03 Sub LT and im running 2 15 L5 with a 1500d Directed Amp. And mine play's just fine as long as I dont turn it all the way up. Its to much power. I do use a platinum battery and use the largest stock alternator. I think you will be fine with a 4.0 gauge amp kit. if thats what you mean by the easiest way to wiring it.

Should I just splice the line out convertor into one of the rearmost speaker wires? If thats the case couldent I just pull the top part in the rear down and splice into one of the rear speakers on the top in the trunk?

Something like that work? Looks just plug and play if itll work

it is preferable to do it as close to the head unit as possible.

Will that "Amplifier integration interface" from PAC work? Or should I just get one that splices in?
Which wires are the ones for the rear most speakers?

Thanks!

Just want to confirm that the PAC AOEM-GM21A plugs right into the stock harness and gives you all the plugs you need to run an amp, no splicing the stock harness.

from the looks of it does fit yours. and to add a sub amp it looks like you use the "C" cable in the kit.

I just installed this one:

$20 at walmart is works great. I had to splice in wires behind the headunit though.

I installed the PAC unit on my 07 Tahoe, but the GM21A does the same thing. You unplug the 2 wiring harnesses from your head unit and plug them into the PAC unit. You then plug the 2 harnesses from the PAC unit into your HU. Run RCA's and the remote wire to your amp.
