Poor show if the amp doesn't have a bridge mode speakon connector!

A reasonably neat way would be to get a speakon-speakon inline coupler and a single short speakon-speakon cable, cut the cable and put spade lugs on the loose wire ends.

Or if it's a permanent change, just cut the speakon off one end and use the wires!
I wouldn't recommend that though. Speakons are well engineered connectors, and binding posts are horrid!
