Firewall quesion

[MrBmx]

im trying to install an amplifier and sub into my sisters 2003 Mazda6, im having the worst time ever finding a place to run the power wire through the firewall.

has anyone done this themselves? can someone help me out maybe show a pic of the way they ran their power wire and if and where they had to drill a hole and if there is anything behind where they drilled..... any help would be amazing.

thanks in advance.

I am about to do this soon too. What I have read...

On automatic models, there is a white piece of plastic on the firewall above the break pedals. I guess you can take that out. Then behind that there is a gromet that you can feed the power through to the engine bay.
[oh and i guess its a good thing to drill a whole in the plastic and put a rubber grommet in that two.]
