per the boards advice i went to radio shack and home depot- unfortunately RS was not much help, so i turn to my brethren here. i'll have runs of about 25 - 30 feet for my rear surrounds-- can i use 16 gauge (from Home Depot). they had two kinds, one was 'digital' and was $25 for 50'. the regular one was $13 for 100'. which do you recommend? do i need digital? also, the guy at RS said i couldn't use coax for the sub- but i know it's been recommended here. can you guys lay out exactly what i'll need to do this? name/type of cable, connectors, etc.. thanks again!
