C4 - Where to hook up powered sub?

[Digital Disaster]

I've got a 96 Vette and a self-powered bazooka subwoofer. I'm assuming I could hook this up at the rear factory amp, do I need an interface of some sort and does anyone have a photo of this type of connection? Thanks!

On my '90, the speaker wires are above the rear speakers, just pull the rug back and you should see them. Check out your FSM for rhe correct color of the wires, but there should be a power, ground, and two wires for the speakers.

Thank you very much!
