Run phone line and Cat5 computer network behind where the receiver/dvd player will be. Things like DirecTV want a phone line and Fios/Uverse with down-loadable content will want Cat5 network.
Run CL2 or CL3 12 ga speaker wire to the speaker locations. Pull enough wire to create un-broken runs from amp to speakers. Run through plastic electrical outlet box's and drill holes in blank wall-plates. Do not spend the $65 each for the wall plates with the binding posts. You can buy a spool of "Carol" 12 ga in wall wire from Home Depot or order from
Parts-Express.com - Speakers, Speaker Building, Home Audio and Video, Pro Audio, Electronic Parts & Accessories
Measure the in-wall distance to the TV from the receiver/DVD player. Order a "Belden" HDMI cable and a component cable from
Blue Jeans Cable -- Broadcast-Quality Cables at Reasonable Prices
If the electrical guy does not have in-wall 12 ga, use 4-conductor, 16 ga wires and twist two of the wires together for "+" and two for "-". Many high-end installs use this.
Have the electrical guy zig-zag the wire between the studs and tack in place with insulated staples pounded in HALF WAY. Years from now the ends of the wire will become oxidized and you simply tug the wires to pop the first staple to give yourself some slack.
Run speaker wires like this:
- 3 to the front
- 3 to the rear
- 2 to the sides
This way you are ready for a 7.1 system if you want.
Run ordinary RG6 CATV coax to the location where the subwoofer will live. You can install "F" connectors and some "F-to-RCA-Male" adapters from Radio Shack.
Try to have the electrical guy install all the AC wall outlets from the same "leg" of power and only power the plugs in that room from that run. Lights and other things should go through some other wires.
POWER CONDITIONER:
Skip this for the moment. You can always add it later. Usually only people living in inner-city where there is lots of AC activity notice improvement with a power conditioner.
