Yes four speakers per channel can work very well if the speakers are matched (same make and model). You put two pairs in series and then put the two pairs in parallel. That comes out to exactly 8 ohms which is ideal.
(pair 1) 8+8 ohms in series = 16ohms
(pair 2) 8+8 ohms in series = 16ohms
pairs 1 & 2 in parallel, that is 16 / 2 = 8 ohms
Be cognizant of polarity. The series goes + to - just like batteries gang together. Then the two groups of pairs go plus to plus and minus to minus.
Then both left minus (Sp1 & 3) to the amp minus and both right plus (SP2 & 4) to the amp plus. If you get polarities mixed up some speakers will try to cancel each other out acoustically and it will sound bad!Edited by Glimmie - 2/14/14 at 2:50pm
