hi. back to this marine install... i almost forgot that my friend wants to be able to attach headphones so that he doesn't have to play the stereo real loud while he is driving around, since the engines make a lot of noise. does anyone know of an easy way to do this, or of a good head unit that has a headphone jack. i had planned on getting the Pioneer deh-p6500. thanx again.

You probably could make your own HP circuit on this deal. Just wire in the appropriate size female jack (1/4" or 3.5mm female stereo jack) off your HU front speaker wires. Some jacks come with shut off connections that when the phones are inserted, the jack shuts off the front speakers.
Then, you can fade the HU to front only and not have any problems with audio noise late at night. The trick is getting a good set of headphones that capable of blocking out some of the engine noise. Studio grade or DJ, mixing headphones are great... but expensive.
Lastly, if your HU puts out too much volume to the HP's, you may have to wire in a resistor (L-pads) which will attenuate (reduce) HU volume.

interesting idea... i think i understand what you are saying. where can i find a female jack that is ready to be wired? or should i just cut one off of an old set of headphone jacks?
also, if i'm only using the pre-amp outputs on this deck, how would i get the amps to shut off when the headphones are plugged in?

I did something similar with an RV install a while back. Wire the headphones to the rca jack on the deck, works just fine. He had bose headphones that had a seperate volume jack on them. Knowing bose though they probably cost 200 since they get $400 for an overgrown clockradio.............

Bose has a real nice pair of noise cancellation headphones that eliminate outside noise while you listen to music. they cost about 300 tho, go firure..

I wonder if you could just turn a LOC(Line Out Converter)backwards by backwards I mean plug a short RCA chord into HU pre-out then into the output side of the LOC then wire speaker leads from LOC to a HP jack...Hmm.
You could also defeat your amps with a toggle relay when you want to use your HP's.Just thinking outloud.

the problem is, i'm gonna be using all the preouts for the amps. also, this needs to be a universal headphone plug, b/c i don't know what headphones he is gonna be using. i can hook the amps up to a switch so that i can turn them off. i'm just wondering if i should try to connect the headphones to the hi-level outputs, or split (say, the front pre-outs) so that they can go to an amp, and somehow to a headphone jack.
swez on 04/19/2004 21:32:21
I think there are such things as headphone level preamps that may operate well off RCA line voltages. The trick here, is to be able to shut off the the amps and speakers (REM) line disconnect so that only headphones and preamp are activated. All other gear is disabled.

I have an idea, lets's see how the golds fell about it. If you are going to run all four channels(FR, FL, RR, RL) and sub, then first you put a switch on the remote turn on line for the amp, if amp has no power then subs make no sound, then then you place a single swith that when turn off will break the ground on both the rear channels. Now for the fun part wiring in HPs, I think i've found a solution, run 2 sets of wires off of each of your front channels, one set from each channel will go to each speaker as normal, now combine the negative from both of the the second sets of wire from each front channel. Ok, now with that is settled use this inline phone jack http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F011%5F003%5F001%5F004&product%5Fid=274%2D274 and wire the combined negatives of the second set of wires to the negative on the inline jack, and wire the positve of the second set of wires for the right channel to the right on the inline jack, and same with left. Now with that done you can plug in you HPs. This is just some extra here if your friend will be going fishing in this boat or whatever where he would like to move around while listening to the HPs without getting tangled up in cords check this out http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F007%5F003%5F006%5F000&product%5Fid=33%2D1196 now of course if you use this you will need a 12v to 120v converter which you can find at your local walmart, and just plug the converter into the cigarette lighter and if the boat doesn't have a cigarette lighter then just hardwire the converter to the battery, now plug the wireless HP transmitter into the converter.
Well I hope you can understand. What do you think golds.

I think this is very hard to read Crash... looks like one giant run-on sentence... LOL But seriously, that could work.
Cordless headphones would be nice if you are fishing but don't want to deal with extention cords.
Since you are already using all the RCA outs for amps, do you have speaker outputs available from the HU? If yes, these can be used to drive headphones. You may have to install a trim pot to keep the input level to phones at a level you can tolerate. Most phones will put out plenty of SPL with less than 1 watt of input.
Swez
cybersailor420 on 04/20/2004 18:36:05
that sounds pretty good Crash. i'm not using any of the high-level outputs, so they are all available. and i did plan on putting in a switch for the remote coming from the deck.
i can't get much info from that link... are you sure i can just wire speaker wires straight into that headphone jack? thanx alot, good research too!
-Ian-
swez on 04/20/2004 19:56:47
Yes, you can wire the female jack from R&L channels off the HU that are amped. However, your HU has what... 20-25 watts RMS power per channel right? No headphones I ever used can handle that much power.... most HP circuits operate close to 1 watt and deliver well over 90dB of SPL.
Hey, you can try it... but don't be too surprized if you get so much volume at phones, you have to add a separate control knob (Stereo L-pad) to dial back on the power to phones.
Here's a 3.5 mm female stereo jack for panel mounting: 2 pack

Thanks, that means alotto me that you guys liked the Idea. Yes I agree an L-pad should be used if going with regular headphones but if the wireless HPs are used, they have a volume control on the HPs, I know it sounds like I am really trying to sell their product but I'm not I am just amazed at the price of the wireless HPs, of course I don't really know about the qaulity but it doesn't hurt to try. I also found some regular HPs here

hey guys. thanks a lot! i think you covered it all. i'm gonna go with that female jack and the L-pad, since i don't know what headphones he will be using. good work, as usual.
