Accidently Plugged Speakon Cables In Wrong

[Jazz Ad]

Now you know that you only need one cab. That's less stuff to move around.

if it was a mono head, then those two speakon outs were connected to each other anyway ("parallel") just like the two speakon ins on the cab were already connected to each other. two cables at the same time did absolutely nothing except add up to acting like a fatter cable (like andyman pointed out).
