I was in the process of installing my new cd player today and I ran into a problem with the speakers.I can't get them to work!!!I noticed that they have alot of wires and they look like they have a amp built in or something.Do i have to buy a harness to plug into the wires or can I pair certain wires together to get them to work,or do I have to buy new speakers?Whats the deal on this set up?
