Wiring audio jack

[scudsucker]

I put this in PC Hardware and Gadgets as there is not really a better place for it - I would guess people here have decent electrical knowhow.

I have a Tivoli Model One with a Model Two subwoofer.

Model One - The best AM/FM radio on the market

With an analog tuner that brings clarity to many of the weakest stations, the Model One radio offers classic style and superior audio from its acoustic wood cabinet.

www.tivoliaudio.com

The subwoofer connected to the radio via an audio jack attached to a 2-strand cable lead (this cable looks like standard 2-strand electrical cable)

Unfortunately my puppy ate through this cable some time ago, and I have lost the original audio jack. Now I am spending a lot more time at home, in an "office/storeroom" away from my home sound system I want to fix the Tivoli.

I opened the subwoofer. The two-strand cable goes directly to the speaker, there is no amp or anything in there. So the radio part drives the speaker directly.

I have a large number of headphones from various sources. However, these are all cellphone headphones and have multiple wires (and the head of the jack has multiple "connection" bands, separated by thin strips of plastic). Most of them also have volume control, which probably complicates things further.

From the internets, it looks like I want a mono headphone jack, but I do not have one. Is it possible instead to cannibalize some earphones to wire up to the 2-strand cable? Will the tiny thin wires in headphones carry sufficient power for the subwoofer?

Why not just use a separate piece of wire entirely? Not sure why you want to use the wire from headphones specifically.

I need the headphone jack for the subwoofer "out" on the radio. On my other system, a Harmon Kaader, the output to the speakers are red & white "clips" that take two wires per channel. On the Tivoli, the "sub out" is simply a female audio jack.

I do not have any other audio jacks to use.

1. Does one of the jacks that you have available have 3 'segments' (TRS or tip,ring,sleeve) or are they all TRRS (4 'segment') ?

2. Are you sure that the subwoofer outout is via one of these small jacks? These are normally used for line level signals, but you say the sub has no amplifier.

Hmm. I last used this system more than 13 years ago. Perhaps I should have done a bit more research! I googled, I should have started with that before cutting up headphones.

The Two is a second speaker, not a subwoofer. I can scavenge an RCA jack for it. I should have noticed a lone RCA output.

The "sub out" is a standard audio jack, but it seems I was trying to connect the wrong thing....

5 minutes tinkering with the correct output, and I now have it working.

Thanks for the help, sorry to waste your time.

Why not just buy a mono RCA cable from just about store?

Zakspeed has by kind of wire you could need for this application without butchering anything.

HDCabling and many others can likely hook you up too.

I see you came right.
