OK, so I returned the 100' of Monster speaker wire ($138) and picked up 150' of CL-2 12 gauge at monoprice for $58 including the shipping.
Another question - I'm thinking of having my sub very near or possibly under my HT components, which will be on shelves mounted on the wall (indicated in blue). Does anyone see a problem with the sub located this close to the HT components or even underneath it. And when I say underneath, it wouldn't be enclosed from all sides, just probably a shelf a few inches above it would be it.
