This is probably a basic question and after doing a search I'm not sure I understand my options, I have always used wiring harnesess and installed aftermarket head units in my vehicals but I'm trying to help my son install a system in his truck and he wants to use the factory head unit because of the controls on the steering wheel, I pulled the dash apart and have reserched how and where to install the adjustable line output converter and I will use it to get the signal to the amp I am installing for the subs, I understand I will drive the new door speakers with the head unit because a converter may degrade the signal which will be more noticable on the mids and highs. I even have my truck box for the subs and have no promblem setting this up but I do not understand the blue remote amp wire. Of course in the aftermarket wiring harness I have always had a blue\white or blue wire set up for that and in doing some research I need a 12 volt signal that turns on when I start the truck, on the back of the factory stereo I have identified the four sets of speaker wires and then all it has is the black\white ground, and 2 orange wires, one being the power and one being the connection to the steering wheel controls, it is a 2006 silverado truck and I believe this is correct as far as the wires. I believe I understand in some cases people wire the blue wire to the ignition but I would ask if someone here can provide a link on how to do this as one option for I'm not confortable just playing with the ignition wiring. Also is it an option to wire the blue remote wire into the power wire on the stereo or is this not a 12 volt signal? That would be easier if it's an option but I could not find any info on any one doing this, are there any other options that anyone can share with me? I appreciate any help that anyone can give me. Thanx, Terry

I just used a switched 12v source from the fuse box of my truck.(the one IN the truck) A unused fuse would obviously be the first choice. Hope this helps, but I am a newb... ;) Has worked w/ no problems for over a year.

Riverrat, how would I wire something into the fuse box in the cab and are you saying I should use the fuse for the ignition? If I use the fuse box would the amp always be on? Boogeyman, I think the guy across the street has one and he would probably help me use it even cause he is just that kind of neighbor, what would I ask him to help me do, or for that matter actually teach me to do, I always want to learn new things and I do enjoy car audio, there is always something new to learn. Thanx for the responses guys, Terry

You can use the multimeter to find a switched 12v source. Any will really work. You probably know this but, switched means its only powered when you turn the car on. Like a radio fuse, some cig lighter fuses, ect.. What I did on mine is just stick the remote wire in with the fuse. Maybe not the most proper way. But like I said, havent had a problem in over a year. Was easy enough to do since my fuse box is in my kick panel. If anything I said is wrong someone will correct me.

The remote wire for the amp is what tells the amp to "turn on" and "turn off". Without it, the amp would always be on and drain your battery. This may or may not be news to you.
This wire needs to be hooked up to any wire that reads +12V when the car is on a 0V when the car is off. This is why the ignition is a popular choice. The ignition wire is "hot" with the car on and shows no voltage (or very very low voltage) with the car off. Tapping into this wire would work fine for a remote wire source.
Although it works, i do not recommend wrapping a wire around a fuse and then sticking it into the fuse box.
If you want to use the ignition wire, it is the pink wire in the ignition harness (i have an avalanche).
