That, my friend, is complete bullshit. I had my radio disconnected for 4 hours while I ran my wires for my sub and she works just fine. No codes or secrets.

no. you're going to need to splice into a fuse that gets power with ignition. I am assuming you also have an RCA converter. There aren't RCA outputs on the back of the stock HU. This project for me was a bitch. Search around this site, there is already a DIY thread started on the install. Good luck
