Peice of Scheiss Stereo

this may sound really stupid but i'm getting desperate....i drive a '94 regal gs with the stupid factory amplified sound system and i need to figure out how to rewire it to accept a new cd head unit....plz help me!!!!!!!!

you can buy wiring harness kits that have the block connector to fit the factory harness that is plugged into your buick radio and loose wires that coinside with your new aftermarket radio the kits are sold at most autoparts stores and walmarts and meijers in the auto section
