Where do you recommend running Power and RCA wires from firewall to amp install in tirewell? would you run power wires on either driver or passenger sides and RCA on side of middle hump?

What is best place to run 8 gage powerwire through firewall?

 

Run the power cable through the firewall just to the left and down from the battery. There is a grommet there that come out behind the A/C unit in passenger footwell. Cut a small slit in the grommet with a Xacto knife. Then wipe powercable down with Armorall and slide it through. The Armorall will keep the wire from pulling the grommet through the firewall.

I ran the power down passeneger side, RCA's down the left, speaker leads BACK to the front up through the middle.
