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
OR
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

Nov 17, 2014 02:02 pm 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/parallel...you have an 8 ohm cab.
Two 8 ohm speakers wired in parallel will give you the 4 ohm cab.
Dis help ya?
