In our opinion, the best rigs are the ones held together with duct tape and wired up with leftover speaker cable, but if you're looking to class things up -- and avoid any number of potential fire issues -- NASA's got you covered with the agency's official Workmanship Standards Pictorial Reference. The exhaustive guide covers everything from wire splicing to connector tightness, and if you're opening up walls to install a home theater or just trying to build the prettiest casemod on the block, it's well worth a look -- the rest of us can stick to using chewing gum and prayer to keep our gear running.
