If you wanna bridge that amp on a single d2 sub, you have to wire it at 4 ohms. I dont think that amp can handle anything below 4 ohms bridged. So wire the sub in series. Take the + from one voice coil and run a wire to the - on the other coil and the last two, just run them to the box terminal.

That amp appears to be stable @1 ohm bridged.

If you only have one D2 sub just wire it in parallel to get a 1 ohm nominal load. + to + and - to -

That amp is class ab and should pull crazy amounts of current bridged @ 1 ohm if it does rated. Any electrical upgrades? what sub?
