Yeah, just like he said, you're gonna have to tap into your rear speakers and use a "line level converter" it converts speaker level inputs into RCA inputs that you can plug right into your amp. Can pick one up at radioshack or a local audio shop, 8 bucks tops. As for your amp, run your power cable off your battery as always, and ground the amp to one of the tie down bolts in your trunk. The only tricky part is you need to run a Remote turn on wire. This turns on/off the amp when you turn your key to on/acc. You can tap into the fuse for your radio or your cigarette lighter. These only come on when your key is on! Good luck!
