Don't go to Circuit City, Best Buy, or any other major retalier. Find a locally owned car stereo shop and take your equipment and wires with you. Ask them how much it would cost to install your CD player, and run the wires for your amp. Since you have the amp kit already that saves you $40 immidiately. I had my amp kit installed for $70, yours should be around $40 since you have the wires already. The CD player will run about $40 to $50 to install. If you have any reservations about running the wires yourself..DON"T do it. You will spend even more money fixing your fried wires and maybe your electrical system in the car. Let a Pro do it if you not an experienced "Do it Yourself" person.
