Silly question, I know.
If I'm using a Marshll JCM800 50W head, and a Mesa 4x12 cabinet, with the following as the jack plate in the back- if I plug one cable from the output of the 800 to the bottom left jack, does that mean I set the amp to 4ohms? The amp has 4, 8 or 16.. the "split for stereo or bi amp" part confuses me..
