druiem,

Perhaps it is just my local Home Depot store, but be aware that they might carry only up to 14awg. Speaker or lamp wires 12awg or greater are not that common. If you do not want an unexpected wait (I know you are excited), you may want to go ahead and order the wires at places like partsexpress.com, who in fact carries "branded" bulk wires at better prices than Home Depot.

Cheers!
