I allways run mine off the battery to a fuse block(sized for the amp)

I suggest running it directly to the battery.

I'd run off the batt as well. If you pull off your right front tire and wheel well trim you'll see the grommet to run your wire into the car. Easy install.

I know how to do it on the Cougar. I'll have to do a search for a how to on the Mustang. I've been considering doing it myself.
