I have a Jensen head unit that (for some unknown reason) never fades competely to the front or back speakers. At most it only fades to about a 30/70 ratio. And- yes that is the way it was designed- there's nothing wrong with the unit. Here's my problem. I hate Barney- that big, f'ing purple dinosaur. My kids on the other hand love him. When they watch the video in the back through the drop-down monitor....I can't totally fade the friggin singing purple nightmare to the back speakers so I don't have to hear him!!! The guy at the local car audio gave me 2 relays (tyco V2324-A1001-X036, 5 prongs) and a basic on/off (pos/neg wire) toggle switch. Apparetnly once connected it will let me cut off the front speakers leaving me in blissful quiet while Barney cranks through the back speakers. Here's my question......HOW DO I CORRECTLY WIRE IT!!! FYI, I have a 2005 Nissan Armada and a Jensen (VM9312) head unit.

I don't know of any way this can be done. You are stuck with Barney. Sorry. Just kidding, if nobody helps you by this evening I will post some instructions.

Remove your radio from the dash. Locate the white and grey pairs of speaker wires. Cut the solid white wire at the connector that connects radio wires to the wires of the vehicle. Connect the wire that comes from the radio to terminal 87A of one relay. Connect the wire that goes to the speaker to terminal 30 of that same relay. Now with the second relay do the same thing with the Grey wire. Now to power the relay ground terminal 85 of both of the relays. Connect terminal 86 of both relays to one of the terminals of the switch. (assuming it has only 2 terminals. If it has 3 terminals let me know) Connect the other terminal of the switch to a switched power source. When you turnt the switch on it will energize the relays and break the connection of the positive speaker wires. If you need a picture I can draw one tomorrow. You can tap into the red wire of the radio to supply power to the switch.

Okay, so my question doesn't actually follow the thread, but could you use this same technique for a remote turn on wire for an amp? In case I'm not being clear, I've included a ghetto picture: It makes sense to me that you could, but I have to ask. -------------

You could do that for an amp, but I would not reccomend getting the power source from the battery. If you forget to turn it off your amp will stay on. Feed the switch with the amp remote wire of the radio.

Or as a last resort an accessory or ignition source that will turn off with ignition. I would suggest a low voltage trigger may work in that application and it could sense an audio signal as a turn on. Only bad thing is in between songs on a CD it may shut the amp off.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

Ah, that's what I was afraid of, but it's not for me, I was planning on getting a small set up for my dad for his birthday, and he didn't want an after-market head unit, but since him and my mom swap cars all the time it needed an on/off switch since my mom can't stand bass, in anything, and I mean anything, don't ask me why, I couldn't tell you. Any other ideas? -------------

Most factory radios do not have an amp turn on wire. You will have to get power from a switched source. Depending on what kind of vehicle, you could use the switched wire on the radio.

Yeah, I knew that already, which is why I was gonna give him my old Alpine HU, but he wanted to keep it factory, which is why I postulated the toggle switch with the power lead tapped from the factory HU's hot wire. i am an idiot wrote:

It's a 2005 Mercury Mountaineer, soo, the color of the switched wire would beee...? -------------

It will be either BLACK/ Pink. Or Yellow/Black depending on the motor option and the Mach or standard audio system. Use a volt meter to verify this before just connecting one of these wires.
