Simple.

You don't.

Just get a single amp capable of driving the sub properly.

Helpful info: do not do it! Use only one of those amps. Get another amp if you need more power.

boss is not cool.

Useful info here.

If you try to wire both amps to the sub, one amp will produce more power than the other. Ever if you wire 1 amp to each voice coil (given that its a DVC sub) and gain match them, they will still produce different power at different impedance loads as box rise changes w/ frequency. Each coil will in turn see a different signal, and that will cause all kinds of hell.
