Wiring question for us amps

I have a usamps 400X (two channel) and two 12.2 Orion H2 (2 ohm DVC). The amp reads 2 ohm stable and 1500watts but the positive/ negative are not marked for the speaker terminals. I assume the + is on the left since thats the way it is on my other us amp. How should I wire these for a 2 ohm load?

See https://www.the12volt.com/caraudio/woofer_configurations.asp

The amp is two ohm stable per channel and thus stable at no lower than four ohms with the channels bridged.  Your DVC 2 ohm subs will not combine to 4 ohms, so you'll have to go to 8 ohms.  I would think the positive terminal is in the same location as your other US Amp.

A better pairing of subs on a two channel amp is to use DVC 4 ohm speakers.  Better, at least, for the fact that the amp would then be outputting power at it's maximum.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
