I left the factory stereo in it's place and run everything off my phone or iPod. I have speakers, amp and a headphone to RCA plug. I have the headphone wire running into the console bucket. I am thinking about moving it to the ashtray. So when the ashtray is open an iPhone dock will be there.
The article below explains it. It is very simple and sounds great. I will never install a stereo again.
