Hi everybody new to the site, I have a question about the wiring harness for the sub woofer that came with the upgraded audio system I have the XLT with the 302A package which does not come with the sub do you guys think that it's prewired where the sub would normally be, if that is the case than I can hook up an amp directly to those existing wires and would save a lot of time perhaps!!!!
Thanks for your help in advance, any advice on a sub/box that fit under the seat in the crew cab perfectly would be a lot of help........
BTW if prewired where would be located in the cab????

 

I cannot say 100%, but my instinct would be that it is not factory prewired. I know the factory Sony amp is normally mounted below the center console/jumpseat area. When I pulled my XLT's jump seat out there were not even any wires where the factory amp would normally be.

For the other part of your question, I cannot speak for an under the seat sub, but I have one of installed behind the passenger-side rear seat and it sounds excellent. Running the power/remote/audio cables from the head unit to the back was not very complicated.

 

The wiring is only there if you have the factory Sony system with the sub. Otherwise, no wires.

 

I answered your other exact same question posting. https://www.f150forum.com/f2/13-eb-w...8/#post5397080
