RCA input kits

[Midwest Express]

Hey everyone, just wondering if anyone has seen or heard of any good kits or modules for adding some RCA jacks to the factory head unit for the addition of external amps.

I am not wanting to swap out the head unit as of yet, but want the ability to add a sub to the system.

Any ideas?

Thanks in advance!

Use an amp that accepts line level inputs,
or pic up a line level converter.

Tap into the rear speaker wires running down both sides of the car, under the plastic molding.

Sorry but I cant remember what colour wires. They're on here some where.
