RM100C internal speaker impedance???

[ctgblue]

It came with the switch set to 4ohms, so it won't blow, but usually amps have 2x8's wired to 16ohms or 2x16's wired to 8ohms.
I've never seen an internal set wired to 4ohms, that would negate using an ext cab.
I'd like to know what to set it to, without taking the back off and trying to figure out the wiring.

There is no manual for the RM100C online.

Thanks

Mine was 8 ohms.

It had 2 16 ohm Celestion G12T75s wired in parallel for total 8 ohms.

thanks, makes sense, but makes using my 4/16 ohm cab a *****

16 ohm + 8 ohm (in parellel) = 5.33 ohm. Set amp to 4 ohms.

I know, I don't have to worry, just sold the cabinet
