Okay I have a house that is wired with 16/2 to two of the three VC locations and then 16/2 going to the speakers. The other VC got 16/4. No Cat5 to any of the VC locations.

What can I do ..

I was thinking of mono-ing the signal then run the 16/2 to a VC and the series the two speakers..

eric,

is the 16/2 by any chance shielded?

no luck there.. just basic 16/2.. it is like the prewire tech didn't know the difference between his wires or something and just ran wire to each location.. sucks because I have to figure it out..

Matrix Audio (speaker wire technology) comes close, but don't think it can handle this job. Control and audio signals over single speaker wire.

by a good amp that is very stable around 3 ohms. feed it mono , or convert signal to mono, put 16/2 on left input of VC with a jumper to the right input. Speakers go as normal. B&K or AudioControl amps should do it. Sonance Sonamps will too. Aint goingto be cheap!

I was going to go with Onkyo TX-8511 for the three rooms.. very basic.

I was just going to set the receiver to mono and shoot the signal to the VC..

If I jump from Left to Right it will kick the ohms to 4 which is pushing it.. if I series them then it would push it to 16 ohms which will work just fine.. or am I wrong on this.

3 pairs of 8 ohm speakers with VC's, if you jump channels together will result in a load SIGNIFICANTLY lower than 4 ohms. 4 ohms if you have 1 vc fed with 4 conductor and speaker per channel - you said you have 1. 2 ohm load with the 16/2 going to 1 vc. parallel these and your load is about 1.5 DISASTER FOR ANY RECIEVER. i would recommend putting the 16/4 on the reciever and getting an Audiocontrol 2 channel amp - stable at 2 ohm for the other 2 wires. Put one 16/2 per channel. Run the amp in mono. Others brands may be too but expect to pay around $ 600 for this screw up

The VC were going to be impedence matching as well as a speaker selector box..

Eric, you've got to work on those hiccups!

I think the matrix audio will work with only two wires. call their tech support. Might be too expensive for this job.

there is nothing wrong with a summed stereo signal to a good speaker. stereo is often overused when there is no true listening area. many amps will let you sum l+r to a single chanel. its realy not a big deal to not have 2 speakers in a casual listening area.
