I recently try to install my alpine deck into my prelude, the previous owner cut the harness wires, so i used installDR to match up the wires wit the alpine deck. I think i wired everything correctly, but the deck doesnt turn on. Is there a way to fry the power wire on the car?

 

do you mean that they cut the factory harness off? if so, then check ALL of your fuses in the fuse panel in the car. there are two wires, a 12v constant and a 12v switched. they are put on 2 different fuses so check then all.

 

You have a blown fuse under the hood. It is a 7.5 amp fuse.
