Sorry I was not clear. I plan on 2 backs and 2 sides either 4 qs8 or 2qs8 on the sides and 2 m2i in the back due to my wife's cabinet(I wanted the 22's). So I have 16g for the backs <35 foot run and the side qs8 will be really long on side That is what i needed to know I will assume that 12 or 14 will work as youn say.Will there be a problem with the BACK qs8 or M2i having 16g Another question I read where the length of wire should be equal Does that mean every riun is the same, or just the run involving r/l for that type eg the side qs8 must be the same 45 feet and the fronts must both be 5ft. Also what about the length of the sub wire? God I love this forum! Thanks for all your help.
