i think if you plug the cd player to the amp and to the speaker, that would might destroy your speakers because its pushing out too much power? there are 2 other plugs that plug into the amp, the smaller one is for the rear speaker and the big one is for power, accessory. um if you look at that wire harness, it should be the same diagram on the install dr
