Andrew,
Sounds like your wiring design is sound. Read the description for the JA Audio stuff that I`ll recommend below to get an idea of their value.

Volume Controls:

Speaker Selector for 8 pairs:

And yes you would need 4 of the IW8BPG for 8 pairs.

> I have wired my `new` construction (I had to gut my house because of hurricane Katrina) for an eight pair speaker sound system for my home. I installed 16 gauge wire with allowance for volume controls for each set (in backless gang boxes), and a four gang box at the location of my sound system. Six pairs of speakers will be ceiling mounted, one set (in my garage) will be wall mounted, and one set will be outdoors.

> Can you put together a proposed `matched` set of the rest of the hardware I need to order to complete my system. I think I still need the following:
>
> 6 pairs round 6-1/2 inch speakers
> 1 pair rectangular 6-1/2 inch speakers
> 1 pair outdoor speakers
> 8 each volume controls
> 1ea. 8 pair speaker selector
> ?? each wall connection plates for the 8 pairs of speakers…I think I need 4 each of these – Speaker Wall Plate 8 Connectors OEMIWM8BPG
>
> I have white faceplate covers for the gang boxes.
> Thanks for your help. I plan to purchase in the next couple weeks.
