Hey I just purchased an alpine CDA-9807 Cd player off ebay and was wondering just how difficult it is going to be to install. I have never done anything like this before, but a friend of mine said he'd help me and hes installed a couple before. Is everything I need to install it right in the box? or do I need something else? Someone had mentioned to me something about an amp wiring kit, due to a built in amp? whats that about. anyway if anyone knows of anything else I'll need or how to install it step by step, (website or something?) I would really appreciate it. Thanks
