JBL Sub Wiring Harness

[JED]

I’m having an Alpine under seat 8” sub installed tomorrow on my non premium OR. I’m wondering if the wiring harness for the non existing JBL sub exists and if so where is the best location to find it? The truck does have the upgraded multi media and 14” screen.

Wondering if you ever found this info, or did your installer just write in the new sub? I also have the non premium OR with the 14" screen and while im satisfied with the sound I'll literally like to add a sub down the road.

I could not find a wiring harness the installer did the wiring. The sub really improved the sound quality . I wanted the JBL system but it wasn’t worth the premium cost for me. I have $600 invested. The installer commented on the significant improvement.

Note: the ANC noise cancellation in the truck interferred at low RPMs . I turned it off with a Carista OBD2. ($44) plus 1 month subscription ($10).
