Hi Team, I'm keen to understand the radio wiring where the Rockford Fosgate Sub is involved.

So I drive a 4007 obviously, my car wasn't fitted with Fosgate sub, but I can aquire one via the wreckers.

I don't expect just to be able to install, find some wiring and it too work...But, is anyone across what would be required for it to function on an existing head unit.

I will add, I don't have the full disply head unit. So I'm expecting to be missing either wiring harness and/or an OEM amp that lives under a seat (for example).

Alternating, I could just drive it via an aftermarket amp, but can I tap into the head unit to grab a source for the amp.

Sorry, lotrs of questions for a new guy to the forum.

Cheers

Brad
