When installing your amp and sub, run the power for the amp on the passenger side and the Rca and signal cables on the driver's side to avoid any interference. And ensure you have a good earth to the bare chassis.

Good luck

There should be a rubber grommet in the firewall just behind the brake-pedal, it's the easiest way to route your amp-wire through to the boot (or wherever you're putting it.)

I spent about half an hour skinning knuckles and swearing until I found it - looking on the forums first next time!!
