Cheap Guy Unregistered guest | I need to know how to install RCA preouts for my factory headunit. 95 Explorer factory head unit. Ok I've been looking at this diagram on how to use the relays so your unit stays on until door is open. I'm not quite understanding the diagram. Especially where the door trigger line is. And you should be using the relays in your fuse box under your hood right? Here's how to wire the head unit using relays so it stays on until the car door is opened as well: http://www.the12volt.com/relays/page5.asp#drto |

Cheap Guy Unregistered guest | Well to get pro install around here cost both an arm and a leg, so I take matters into my own hand by finding someone who can help and make sure I have my father help because he's pretty good with electronics and hooking up stuff, it's just that he's not that good in car audio. I can install head units and amps and that good stuff it's just that I've never done that particular job. Well can anybody in here explain this. I would greatly appreciate it. |

Cheap Guy Unregistered guest | you are the man glasswolf...I'll take your advice anyday. With the information provided I understand of how to do this install and going to try and let you know how it goes. One more question radio accesory wire is the power antenna wire right? |

(usually the red wire on aftermarket head units) |
