[QUOTE="Savant, post: 126050, member: 546108"] You have NO idea what size power/ground wire to tell him to use unless you have SOME clue as to what he is powering.. if you told me to use 8 AWG I'd melt down wire and blow fuses left and right.. The real answer is, it depends on how many watts/amps you will be pulling on the system.. For lower total watt systems, you can use smaller size power/ground wires.. that is, 8 AWG will work for (guessing) 500 Watt systems.. you will probably want 4 AWG wire (smaller numbers are bigger wire) for upto ~1000 watts... etc etc.. The speaker wire depends on the current going to the subs/speakers.. if you are running 1500 watts RMS to a sub, you will need a LOT bigger than 16 gague.. the same principle applies to speakers as the amps (but amps normally drive more than one speaker).. here is a site that you can use to figure out the power wire size.. if you want a better idea of what to use for your speakers, you can change the 'efficiency' to near 100 % and set the main length of wire to ~4 ft.. (or what ever).. that should tell you wire size (to amps, but we are replacing amps with speakers in the second instance).. hope that helps..
