I am a noob at car audio but how do you install cd player and amp in a 90 civic hb? which wire is the remote wire to turn on the amp?
thanks

 

the easiest way is to go buy a aftermarket wire harness to plug your factory harness into your new radio. the new wire harness then should match up color for color. The old radio comes out from behind with 2 8mm screws.
remote turn on for amp is usually blue or blue /white.
and please make sure u fuse your power wire to your amp under the hood.
run the wire through a grommet in the fire wall. Not through your door jam.
also have a good clean ground for the amp.

 

Thanks alot for your info.

 

Do you have to put a 0.5 amp fuse for the remote wire?

 

the remote turn on wire is blue and white.
