Where to run power wire through firewall.
Where to run power wire through firewall.
Hey i just wanted to know where i could run a 4 gauge power wire for an amp through the firewall of an 03 Astro without drilling. On my 91 i was able to go through where the ebrake cable run through, but it seems a lot tighter under the dash of the 03.
91 Astro LT

You can run it thru the rubber boots around the steering shaft.

Or through the heater/AC box if you wanna be sure no one kicks it & grounds it out. Just sayin...
