I've been wanting to replace the audio system (all speakers + receiver) in my car since I bought it in 2001. I think I'm finally going to pull the trigger and get around to doing it. Has anyone installed a system themselves? Is it too difficult? All the videos and stuff that I've found online make it seem like it wont be that big of a deal and only take a few hours. Is this true? Anyone have any horror stories or "buyer beware" type info they'd like to share? Thanks in advance!
