amp wireing

hey i have a 94 ceilica and i was woundering what wire i should hook up my amp tunr on wire to

the amp should have 3 wires, a power which goes to the battery, an accesory which goes to the accesory wire in the dash, and a ground which goes to a metal piece connected to the body. other than that you just have the rca wires which should hook to the back of your cd player, and the wires that go to your speakers.

im horrible with wiering speakers, but good w wiereing harneses...how does that work? lol
