best way to run an amplifier power wire?

[diecast92]

I've got a 2002 Isuzu Rodeo and am planning on installing a sub/ amplifier in the cargo area. Anyone have suggestions on the best way to run the power wire to the back? Figure I'd ask before I try and see if anyone has any tips/tricks they've learned from their install. Thanks in advance !

I ran mine (8ga) from the battery; back to firewall; over to driver's side; through rubber grommet in firewall (cut small slit in rubber); then popped off plastic kick panel in lt front, front & rear door plastic threshold covers and the plastic panel covering the seat belt anchor pillar. All those panels simply pop off & back on if you're careful. I think I did have to unbolt the seat belt anchor to get the seat belt pillar panel completely off. Was easy to do however. Ran the power line under the panels & snapped them back. Amp & sub are in cargo area on drivers side. Seemed to work OK.

Ran the head unit signal wires & sub shutoff wire to the sub in same manner, but down the other side (don't want power line & signal line together). Also ran the XM antenna line from right rear under the panels on passenger side up to the head unit. The 8ga wire just barely fit. If you're running something like a 0 ga, might be more of a challenge squeezing it under the plastic panels.

I run 2 0ga runs of stinger pro down the driver side through the firewall, underneath the carpet and panels, up into the quarter panel tailgate area.

Remote wire follows same path, any audio signals such as a XM antenna I run through the door sealants.

And last but not least, all RCA and Speaker wire is either running through the roof or passenger side of vehicle down the B pillars when needed.

Remember to keep your power wire as far away from your RCA lines as possible. I have minimal engine noise. My engine noise comes more from the fact that I keep blowing my pioneer head unit ground (only because I like to work on it and listen to it at the same time heh)
