Several years ago, a buddy and myself installed a head unit and 2 12"s. In hindsight, the subs were a waste of money since I never really turned the bass up to fully "utilize" them. Fast forward to today, I sold them and now have a bunch of wires in my trunk. I also have ZERO bass, which is a bit bothersome. I want to hook up the stock 8" sub since it's just sitting there not being used. Do I need to take the head unit out and hook it up from there or is there any way to hook it up from the wires sitting in my trunk? Help would be appreciated!

 

when i had my jensen head unit, my stock sub didnt work, i guess it wasnt hooked up to the jensen for some reason, and my steering wheel radio controls didnt work either,

 

Search in the audio forum you will find what you need here https://acurazine.com/forums/audio-video-electronics-navigation-22/%2A%2Aaudio-video-diy-info-faq-all-models-%2A%2A-299065/

 

if your wanna keep steering wheel controls you'll need a specific(to your car and deck) module that'll maintain that feature.

 

you have to buy a different wiring harness made for the steering wheel controls....personally i wasn't worried about it.

 

I will be up in your area in 3 weeks visiting some family if you want to come by my crib up there I will be morethan happy to help you throw it in. We can use the wires in the trunk (if ran correctly) and kevin at audio works (florence,ky..... small drive but well worth it) probably has somethings we can grab for CHEĀP... thas french for inexpensive. =) kicker dealer...

Got a L7 15 there for the a bill.

he has JL also which I personally have not utilized in a TL yet, but think we could doin just about whatever with sub.
