Mantis,
Your description is confusing. Let's define the possibilities clearly:
1. Full Range pair of speaker cables - This is just a pair of cables with a positive & negative at the amp end and a positive & negative at the speaker end. To connect a biwirable speaker with these requires a set of jumpers.
2. Internally Biwired pair of cables - this is a single pair of speaker cables that has a positive & negative at the amp end but breaks out into two positives and two negatives at the speaker end. These do not require any jumpers.
3. Double Biwired set of cables - this is the ideal way to biwire with two full range pairs of cables.
I suspect that what you have is a full range pair of cables with a set of jumpers. If that is correct, then I would recommend getting a second set of identical (or nearly identical) cables and do a true double biwire.
A second (less ideal, but workable and less expensive) option would be to have your cables reterminated for an internal biwire, assuming that they are of sufficient overall gauge and have the necessary individually insulated internal conductors to be used that way.
The least appealing option is to use your full range cables with the jumpers. But if you have to, I would recommend running the negative speaker connector to the BASS- terminal and the positive speaker connector to the TREBLE+ terminal on your 5A's. Then connect your black jumper between the BASS- & TREBLE- and connect your red jumper between the TREBLE + & BASS +.
