Two speakers off of one wire? - AVS Forum
2-Channel Audio > Two speakers off of one wire?

I accidentally ran only one speaker wire behind walls (which are now newly sheetrocked) and need to connect a pair of speakers in another room. The 2nd room is on the floor above and it's impossible for me to run a 2nd wire now.

So my question is, is there any way I can fix this mistake and still connect both speakers? Can I assume that if it can be done it would end up being mono instead of stereo?

Thanks!

Correct, about your only option is to use one speaker....mono.  smile.gif

Thanks for the quick reply! I need to get a little more specific now so that I don't screw this up:).

I have a L & R output on my amp that I need to connect to a pair of speakers in the upstairs room, BUT only have one wire (2 conductors). So exactly where do I connect that wire (on the amp side and the speaker side) to get mono sound to both speakers?

You just connect it to the L output and do not connect the other channel.

The speakers will be wired in parallel, which gives a lower impedance, but that will probably be OK since you are only driving one speaker.

Thanks for the response. We're getting closer. I understand about just using the L channel, but I'm hooking up 2 speakers, not one. How should I connect the speakers?

You would need to solder 2 wires to the one that comes into the room.
This will not give you mono sound though. You will get only the right or only the left channel.
The solution you propose would be unsatisfactory to me, but to each their own. I would try to use the one wire you have to pull 2 wires through the holes behind the sheet rock. Failing that, I would find a wireless way to get a signal to second amp in the upstairs room.
Anyway, good luck.

I would do as 2obed suggested and tape two speaker wires to one end of the existing wire and try to pull it either up or down the wall. Whichever way you think it would go easier.

Otherwise you are going to be really good at sheetrocking and mudding when it's all said and done.

How can one speaker be wired in parallel?

He wrote "speakers" so I think he was thinking using both speakers in parallel connected to one amp channel...but all comm knows for sure what he was thinking...

the rest of the sentence says he's only driving one speaker...but, your right, who knows what professor commsys is ever thinking.
