    A) For a 4-conductor Speakon to banana plug cable... The banana plug side has a "ridge" on the pole with the green & white wires. The other pole has red & black wires. 1)What does the "ridge" mean? 1) Is the "red & black" pole positive?

    B) For a 4-conductor Speakon to Speakon cable.. If bridging, does the amp side of the cable need to be modified, or can it be plugged "as is" into the amps bridged output?

    Typically, on a banana plug connector, the side with the ridge or the tab is the ground side. The only way to know for sure is to open the Speakon connector and look at the labeling on that side also.

    If you're only connecting one speaker, it won't be as critical. If you're connecting several cabinets, you could potentially connect them out of phase (where the speakers in one cabinet are moving out while the speakers in the other cabinet are moving in).

    You could also take it to a local store and ask them to help if you're not sure.

    For bridging, rewiring the amp-end plug is in order. Check the owner's manual for your amp (it should be on-line if you don't have a hard copy).

    Usually, bridged outputs are connected to the 1+ and 2+ terminals (while 1+ and 1- are normal dual mono/stereo connections).

    Be sure to mark the rewired end as the bridged amp end.
