guess im going to have to run some 1/0 in my blazer, planning on going with 2 runs a power and a ground. My question is where is the best place to drill?
i want to bring them up through the back. was thinking maybe under thaat trim peice at the very back right before the gate?

 

if you're kind of iffy about drilling a hole in your carpet, you can always take the seats and carpet up and black tape it down to the frame. that's what i did. i have 2 gauge ran through a custom made hole in my firewall. buuut, i don't like to mess with things that shouldn't be messed with.
