I still dont get it because how can you wire up 2-ohms on the speakers? The way you described it, sounded like wiring in 4-ohms, basically, both front speakers on front channels of amp, and rear speakers on rear channels, with pos in pos and neg in neg.
Wouldnt 2-ohms be wired with left front pos with left back pos to amp, and left front neg with left back neg to amp, and the same thing for the right side speakers?
