Aftermarket amp power cable run

[1Bad454]

Looking for ideas of how to run the 4g power cable from my amplifier under my seat to my battery. It's a pretty massive cable to try to hide..

I don’t have a amplifier but just thinking about it I would think your going to have to drill a hole in the firewall or in the back of the vehicle might be easier to go along the inside of frame rail and into the truck area. Just a thought good luck

Either run it along the transmission tunnel or on the outboard side of the floor where it starts to kick up to the sill.
