I'm installing a 10" powered subwoofer and I've searched the audio forum with no luck so I'm posting here since there has to be someone that knows where I can tap a full time, unswitched hot wire under the dashboard. I don't want to run a hot wire outside the cab to the battery + post so I plan on finding a full time hotwire in the cab.
I have the two factory service manuals but electrical diagrams are apparently a seperate manual.
Anyone know what wire would be a good candidate for tapping?
Thanks...

I would think the amperage of the powered sub would reguire you to run a wire outside the cab to the battery. I doubt any internal wires have the capacity.

Thanks.
Now that you mention it...
The sub has a 20 amp fuse in it which would indicate a BIG current draw.....
Finding a firewall feedthrough on a '97 F150 ain't nearly as easy as it is on my '70 Ranchero!

Look for a rubber grommet in the firewall. Or go through where the wiring harness from the engine compartment goes through the firewall.

x1, you need to run an amp kit directly to the battery! You will have big problems in the future if you dont!
