My amp is a qsc powerlight 4.0 . In stereo mode 8 ohms / 4 ohms / 2ohms my question. Is how many 8 ohms speakers can I put on per side on the amp,
1 speaker = 8 ohms
2 speaker = 4 ohms
3 speaker = 2 ohms
1 speaker = 8 ohms
2 speaker = 4 ohms
3 speaker = 3.1 ohms
4 speaker = 2 ohms
I heard a lot of story's that you can load 4 speakers per side on a amp is that true? I know for sure that the qsc powerlight 9.0 PFC. Can't do 2 ohms load stated on the manual both in stereo and bridge

I'd say that would come down to how you wire the speakers.
Series will add the ohms of the speakers. So if you wired two 8ohm speaks in series, you'd have a 16 ohm cab.
Keep adding speakers (in series) and you add ohms.

EDIT...just did some double checking and if you wire two 8 ohm speakers in series/ have an 8 ohm cab.
Two 8 ohm speakers wired in parallel will give you the 4 ohm cab.

Dis help ya?
