Aside from finding a precarious position and proper drilling location, is there a quicker, easier, and cleaner method to running 0 gauge wire through the firewall?
I've seen two posts on here that both describe running 4 gauge or lower wire through two separate locations (the lone center-ish firewall grommet and the smaller hood latch cable grommet) but they really don't help in my situation..
I'm doing a full sound system overhaul and need the power of my Knukonceptz 0 gauge wire to distribute to two seperate amps.
Willing to hear any suggestions but hoping to hear from someone who's done this before with clean/good results.

 

so why doesnt the firewall grommet help in your situation? its big enough for a 0g to be pulled through..
