Default Stock Subwoofer/amp with aftermarket HU???

Ive found a couple of things with the search but nothing about these harness. I just ordered my Dbl-din AV and I would like to just use the stock sub without having buy an amp and such.

Will these harness allow me to use my stock stuff with my aftermarket Headunit. Thanks in advanced.

If not what can I rig up for it to work??

i wasnt able to use my stock subwoofer. It didnt matter tho bc i was putting in a system in my car. Its been a while since i did this but ill try to find where someone wired up there rear speakers to the sub.

if you follow the thread in the DIY links someone linked how they set theirs up and here is how they kept their factory sub

Alright, so I have done this before, and I will link you to the thread that got me through it:
https://www.clublexus.com/forums/gs-...iy-add-on.html

Also, here is the harness I used:
http://www.amazon.com/SCOSCHE-TA02B-.../ref=pd_cp_e_1

Now, let me just say this right away, the way you are going to be able to keep your factory sub is through wiring it into the rear speakers (or some speakers, your choice I guess). You CANNOT use the factory amp with an aftermarket headunit for our cars (I am assuming you have the Pioneer setup and not the Nakamachi (Navigation)).

It will sound better than the factory headunit, IMO, but the sub will be rather lacking (it kinda is in the first place) and you will get some mids through it, which isn't great but whatever.

What I ended up doing was taking the whole setup out, and getting a new headunit, amp, and sub. That can get pricey real fast though, so I understand if you don't want to, but it is really a better way to go. One other thing you could do for now is to get an aftermarket amp for your factory sub, and then upgrade your sub later on when/if you feel like it. At least this way it will still sound decent and not have mids coming through.

Let me know if you need more help, glad to assist!

Also you can on a budget use the factory sub wire and terminated a RCA connector to get the signal to the back
