Thats paralell, if your sub is D2 then thats a 1 ohm load to your amp in bridged mode which is too low. You amp is only stable down to 2 ohm bridged, Connect the two top middle terminals together, so you will only have 1 wire loop on those top terminals. And leave the speaker wire placed where it is. That will be series and give you a 4 ohm load.
