Adding headphones to the sound system?
Hey guys, sorry I havn't been around lately. Got a new girlfriend, so needless to say my spare time hasn't exactly been spent on here. Actually, she's the reason I'm posting this question.
She loves loud music. I'm talking volume-set-to-11 loud. While I enjoy that every now and then, she's *always* doing it. I've tried coaxing her to turn it down, but that just dosn't work. Hurts my ears and makes it hard to hear what's going on around me. So, my question is: is it possible to add a headphone jack to a stock unit? Preferably something that has it's own volume control (so I can listen at a nice low volume and she can blow her eardrums out at the same time).
I would like to keep my current H/U (stock MP3 player, actually has speed volume!). So I'm thinking there's got to be something that hooks into the audio out on it. If not, I may need to look into building something.

yes you can do this. we hooked up the rca's for a sub this way. just splice into the right and left outputs on the back of the headunit that go to the speakers. splice that with a 2 conductor wire into headphone jack and BAM u have headphones. on the other hand you would have to find out a way to keep the volume low on the speakers and high on the heaphones.

i'd look into some sort of 2 zone option. lots of aftermarket hu's are starting to have this option. basically.. it'll split the sound into 2 zones. you could rig it so the first zone, or the front zone, would be the truck itself... then build the second zone as her head phone jack. with this, you'd be able to control volume independantly.... it could probably be done easily with some sort of simple attentuator. i bet John or Bob would be able to figure it out for a stock radio.

The problem is not making the headphones loud enough -- it's keeping them from blowing.
Headphones make ear-splitting volume with less than a watt applied.
Second problem is this, and I'm warning you that this is the biggest problem: our speaker outputs don't have a common wire. There are two wires per speaker, and they MUST be kept separate or you'll blow the output stage.
Headphones are 3 wire circuits with a common "ground". You simply can't hook them up to our radios without a transformer, or you'll have to take off the connector and split the feeds so that each driver in the headphones has it's own two wires with no common between them.
Ignore this at your peril!
That being said, if you do split the feeds and hook it up, then put 100 ohm, 1/2 watt resistors in series with the headphones. Failure to do so will probably result in blown headphones, or blown eardrums. You may need an even higher ohms value, but time will tell.
Your girlfriend is a bit of a fool, and she's going to regret this someday.
