I'm adding a sub amp and I need a remote wire, where's a good place to tap into one?
For best results just run it to your radio, did it in my car it's not hard and work fine. Did you run you power cable to your battery?
Can confirm that you can tap into the antenna wire, that's what I did. I followed a write up from another forum and it worked perfectly.
