ok, i have to route a cable from the battery to my amplifier in the trunk, but how do i pass the firewall? do i have to drill a hole for the power cable or are there other possibilities?

 

nah, just look for some holes already drilled like where other wires go through, you may need to drill new holes only if its a really tight fit with the wires

 

well, that's my problem. i didn't find any

 

ok, i just removed some more carped and found a good place. but it's too dark to finish it today

i'll post pics of the result tomorrow

 

In case anyone was wondering, there is a post already here about routing cables... posted yesterday! Not being an ***, but in the future, just do a little searching and you can find answers to common questions like yours fairly quickly.

 

I found old bolt holes some holes after I removed the stock heater box. Saved me breaking drill bits ..

 

done!
