What size hdmi (awg) and speaker wire do I need for my home theatre and LCD?
HDMI basically either works or it doesn’t. The link is to an article that compares budget cables to Monster, and concludes that while there are differences in the cables, for most uses (and your situation fits) budget cables work identically to the expensive ones. The only time you need to worry is if total length (you must count the cables on each side of a switch, e.g. receiver) exceeds about 15 ft and/or you are installing the wires in the wall. For budget cables see Monoprice.com (2nd link). For runs over 15 feet and/or better cables (and to read a lot of useful info on HDMI) see Bluejeancables.com (3rd link) Now for speakers. The “rule” is that resistance of the speaker wire should be kept under 5% of the impedence of the speakers (usually 4 or 8 ohms). The table at the last link shows that you are fine with wire at 18 awg or larger at 15 feet for 4 ohm speakers and with 20 awg at 20 feet with 8 ohm speakers (and these numbers are conservative). Hope this answers your question and
