i have a jcm 900 that can run 16/4 ohms or 8 ohms and i have a single roland speaker that has an 8 ohm input, how do i connect them impedance wise?
the jcm runs 50 & 100w if that would make any difference..

thanks!!

so, it's one speaker that's rated at 8 ohms

set the amp for 8 ohms...

What's the power rating on the speaker? that will tell you to run wither 50 or 100 watts from the amp...

now don't crank the vamp too loud now or that speaker will be no more

general rule of thumb is to have a speaker cabinet that handles 50% more than the max RMS rating of the amp..

this roland speaker, is it a cab or an amp?

it's always good to have double impedance on the cabinet, meaning it can take twice as much as the head can dish out.

although, exploding speakers can be a great stage show!

Like everyone else said, use 8ohms for a single cab. If you get a second cab of the same type, set it to 4ohms.
