Connecting dual subs with speakon connectors

@ghdprentice  the high level input is the reconended input for this subwoofer.

@ditusa thank you very much. Sadly the manual has no mention of how to connect two subwoofers...

@noromance ​​​+ @artemus_5 : Thank you very much, I think this is what I was looking for. This makes a lot if sense as the yellow and red wires go to the two positive (red) speaker outputs when connecting one subwoofer. Just to clarify, I would connect one subwoofer with red and yellow to the positive speaker out of the left channel and black to the negative speaker out of the left channel and the other subwoofer with red and yellow to the positive speaker out of th right channel and black to the negative speaker out of the right channel?

Thank you very much for your help!

@the-audiophile-barista perfect thank you very much this is what I hoped someone would write :)

Thank you everyone! I have now connected them as advised by @noromance and many others. It works and sounds perfectly. Thank you for all your inputs.
