where do you guys run your power wire through the firewall on an 03 f150 extended cab?? any help appreciated thanks

 

I ran my 4 gauge through a grommet in the floor. If you pop off the passengers side sill plate, and look towards the front, you can see a grommet about the size of a half dollar or so there. Great place IMO. I can snap a pic if you cant find it.

For my 8 gauge I just drilled a hole in the firewall on the passengers side, right above where their feet would be.

 

I ran mine (also 4 guage) accross the engine (through some shielded plastic) to the drivers side, then through a grommit right behind the gas pedal (There's a little plastic cab, drill a small hole and push the wire through, it seals itself)..

Pics in My Gallery of the entire wire route, from battery to amp.

 

cool guys thinks alot!

What year is your truck and where did you ground your amp?
