If the two Cannabis Rex are wired in parallel, that would give you 4 ohms.So I'm putting two 8 ohm Cannabis Rex speakers into my Peavey Classic 50 2x12, but the 1/4 inch prong was in the 16 ohms input, not the 8 ohms. If I'm using two 8 ohm speakers, so I want to run them into that input, or should I run them into the 16 ohms input??
