Jeep: Radio, jeep grand cherokee, rca cables

Question
I have a 04 Jeep Grand Cherokee with the factory ten disc cd changer and amp. I'm wanting to add an amp and subs to the factory stero. There is a website that told me I need to get this "OEM-1 Interface + "ADD-CHR2" and "AMP-RCA" cables" but I can't find anywhere on the internet to get them. Would you happen to know where I could find that?

Answer
John,

In reference to installation, there is no better place than www.crutchfield.com -- while their prices are not always the absolute lowest, their products always ship with quality installation instructions, wiring harnesses, etc for your specific car. Good luck!
