Sound system help needed!!!

I have a standard Golf mkIV '00, with which i have been playing. I have added a sony md player, a shark 1000w amp and two rear speakers. I have now purchased a 12 JVC cd changer, with a mini amp thing and remote control. any hints on where to start and how to connect it??

Well, first I would scrap just about everything you have and buy something worth installing. What's a shark amp?????

Anyway, you'll need to buy an amp install kit with the proper sized wires and RCA cables. They usually go for $50 to $100 or more for a good kit.
