You'll likely have to have something custom made. You could do something yourself with four conductor Canare 4S11 by running the intact cable from amplifier to the speaker's lower module where you would split out two conductors to the lower module and continue the remaining two conductors to the upper module.
It would result in a pretty clean installation.
I used Canare 4S11 with my VR4 Gen III HSE, and I also used MAS Hybrid Signature, which is another four conductor speaker cable that can be bi-wire configured. AudioParts Inc., the seller of the MAS cable, could probably configure it to suit your requirements.
