Depends if you want to run separate wires for each driver, or one set (+/- servo and +/- speaker =4 individual wires) and then route them between the 2 drivers (for one side)...
I chose to run one set up to the cabinet, then wire it between the 2 drivers.
I used 4 pole speakon connectors from parts express, and bought a custom length "pro" cable for it. I have the amps close to my electonics, and run cable to the drivers. So it was a clean way to run wiring for mine, but a bit pricey.
