...So I thought about it for a second then here is what I ended up doing... I went up into the attic, lowered some speaker wire down through each cut out, and secured a speaker to each wire, and pulled the speakers up (from the attic)... and then adjusted the dog-legs over the sheet rock, Because I had to install them with the grilles already on) and installed wood shims under the dog legs to tighten things up, and then siliconed them.
