stereo wiring, 2000 toyota celica

i have a 2000 toyota celica im installing an amp and speakers on the car. Can someone give me the stereo wiring for it, since the car has a pre-installed amp from factory, im not quite sure how to find the cables i need for the speakers and power... and my other question is where can i connect the power antenna cable right now i have it connect to the fuse for the radio, but is draining my battery because the amp always stays on. i did it on my honda and it worked. i dont how come it doesnt work on the celica. thank you very much, hopefully someone can help me......8d
