Battery Power Cable to Amp Routing?

I have the cable run to the battery but I'm not sure what route I should take to get it to the amp under the front passenger seat. Should I run it along the firewall over to the passenger side and along the door? Or should I run it somehow through the center console? Thanks!

 

Several videos on YouTube
Taco tune has a good one
From battery through firewall on driver side
Run under driver seat to under console to passenger seat

The way the rubber grommet is and where you will clip off the tip of the grommet , you will need to push the wire from the inside the cab to the engine bay. 4 gauge wire will be a tight fit.

I used an sky high car audio ANL fuse holder close to the battery then ran power wire from there

 

I was too much of a wuss to go through one of the existing firewall gromets, i was too worried about disrupting some existing wiring.

I ended up going across the engine bay to the passenger side, to the floorboard under the passenger seat, there's a gromet there kinda where just before the carpet starts to curl up. just pull back the carpet and its right there.

here's a couple pictures from my build

I ended up running it along the firewall in the cab over to the passenger side, through the kick panel, then down into the door channel and back to the amp location. I did find out that being 65, I'm not a spring chicken anymore. It was tough getting into weird contortions to run the cable.
