12v direct to the rear for powered speaker

[keymonkey]

I don't believe there is one, but thought I would ask if there was a fused 12v run to the rear of the truck (74)? I have enough wire to run directly from the battery to under the rear seat, but was hoping not to have to drill holes and loom a single 14G wire the length of the under carriage.

I'm just wrapping up the complete re-wiring of my '69. Definitely no 12v hot to the rear on it, and I've never seen one in any of the wiring diagrams for other years.

Other than the trailer battery charging circuit offered in newer trucks I've never seen that. I've added a battery hot running the rear of the vehicle to almost every vehicle that I've owned in the last 20+ years. Isolated studs are the likely tap-in points, 10 ga wire, fused at 30A

Yep, add your own.
Back then, for a Bronco especially, a “powered circuit“ included a long series of driveshafts and u-joints to a PTO drive mechanism on the transfer case.

Are you suggesting to hook up a generator to the PTO output of the transfer case? LOL

No, a blender.

Or the analog version of a flux capacitor! More power to everyone!
Actually, funny you mention generator. I was actually thinking that when I wrote about the PTO. I bet back in the day somebody had one.
