im trying to figure out the best way to run amplifier wiring to the cargo area on my 2001 blazer 4 door. I have the power wire(4 gauge) coming through the firewall behind the glove box and 2 sets of rca wires for 2 amps but not certain how should I run them to the rear. amps will be wired behind the back seats. any suggestions

 

My battery is mounted in my cargo compartment, so I had to run heavy cables from back to front for my starter, winch, etc. I used these for the battery cables to pass through the floor, and for other cables.
