Glad you posted that pic...gives the answer right away. You will HAVE to get a line converter/driver to use THAT amp, and your stock deck.

That's easy enough. Brands like Scosche, Metra, etc make them. It will be a little black box that has speaker wires coming out of one side, and RCA connectors on the other side. You will have to cut the wires from your rear speakers, and splice them onto the speaker wire inputs on the converter. Then, once you've done that, you will have to run an RCA cable from the converter box to the amp, and there should be small holes in the top of the converter with round switches inside of them that you'll need a mini flathead screwdriver or philips to turn, to adjust the amount of volume/voltage it allows to pass...

This is what I'm talking about:

You need a little box like that, and most car audio shops either will have one, or will be able to get you one. The one like in the link will be easy to find, as Scosche is one of the biggest providers of adapters and installation hardware for vehicles out there.

With a controller/converter like that, you'll be able to keep your fader control, and you'll only run the amp in your stock deck a little under 4 ohms (which it can take, as I mentioned I used the stock deck to interface an amp in my car originally too, with zero issues).

Because of that amp, you'll have to hook up your system this way...

Hope this info helps
