Heavy guage cables are important only for speakers that carry low bass (less than 100Hz). It also depends on how long the cable run is. You do not have to uses special speaker cable; electrical lamp cord will work just fine. The main reason to go for cables designed for speakers is that they are "polarized" (one of wlres is marked along the cable) so that you can maintain proper polarity when connecting speakers to the amp (red to red, black to black, eg). It is hard to tell without an ohmmeter which wire is connected to which unless the wires are marked. Go to your local hardware store or Home Depot. They have polarized speaker wire in various sizes. For main front speakers no more than 15ft from the amp. 16 guage is adequate. for a passive subwoofer, use 14 guage, or if the cable is longer than 15ft, use 12 guage (powered subs don't use speaker cable). For surround and center channel speakers, 16 guage is more than adequate at any length. Get the lowest cost cable that will do the job. use monster standard 16 guage Speaker cable can vary with power output. For the average car stereo, 16-guage would be the minimum...but it doesn't hack it for home stereo. Stick with 12-guage for all home-stereo applications coming off the power amp and going to the speakers. There is not a big difference between 10 and 12...but there will be a noticable difference if you try to go down to 16. You'll lose bottom-end (bass) focus and definition. What brand you use is up to you...there's not a big difference between brands, though many folks will swear by one brand or another.
