Hi guys!!!

I'm planning to install a sound system on my 99 GS...
I have only one question... Thru were in the firewall, can you pass the 12 Volt battery cable? I can't see a space or hole to get it thru...

Any ideas on a good location on the firewall to do this?

edit:
Does the original bracket mounts for the stock radio fit on an after market radio? (single DIN head unit)

Lift up the carpet in the passenger side footwell, you'll see a rubber grommet that you'll be able to pass the wire you need through.. I've passed 4 gauge but there's a lot of room there, you could easily go bigger..

What ^ said. And yes, a single din head unit bolts right up to the existing brackets. Just use the screws supplied with the head unit.

Thanks for the input guys... I'll defenetly try that out...
All I need to do is find the original bracket mount for the radio...
