I have a modded JCM800 (50w) head where one of the speaker outs was used for a knob. So I only have one speaker output left. I received some varying reactions to this idea, so... Is it ok to split a single speaker output using a Y-cable into 2 cabinets? If so... It would be more convenient for me to use a male mono 1/4" to 2 female mono 1/4" adapter and then plug 2 speaker cables into that. Is there any reason to choose a full length all male Y speaker cable over the above approach? In any case, I'll be needing beefy speaker wire to handle this right (16-gauge?)? Is doing this the same electronically as using 2 speaker outputs on an amp? Pls recommend options. Thanks!
