I need help getting through a XD firewall
 

Im trying to find a place on the firewall that I can use for I can run the amp wire though. So any ideas? Any pics? Please help. Thanks

I did a how to on SL a couple years ago on how to do this, its in the tech section.

there's a grommet that is HUGE, with a wiring harness already through it behind the steering wheel. That's your best bet. remove the battery, and it's a LOT easier to get to! good luck.
