TL;DR

Hide every cable from TV to receiver to speakers. The complete guide plus install costs.

The single biggest difference between a DIY home theater and a pro installation: the cables. Pro installs run every cable inside walls, behind the TV, behind the receiver. DIY installs have visible cables everywhere.
