I need help figuring out how to wire my subs to my sub box and from the sub box to my amp. I have a Kenwood KAC- 9106D mono amp, two Rockford Fosgate P2D-4 10 inch 4 ohm subs, and a Atrend Bbox A-202-10p. I have looked at both of the DVC 2 ohm and 4 ohm wiring diagrams but my sub box has two spring loaded terminals one for each sub. Do I use both terminals one for each sub or just one terminal like the diagrams shows. Also my amp has 2 postive and 2 negative speaker terminals. Any help would be greatly appreciated.

You have 2 dual 4 subs that would generally be wired at either 4 or 1 ohm at the amp. the amp is only 2 ohm stable. I would wire them at 4 ohm.
https://www.rockfordfosgate.com/products/details/p2d4-10 click on the wiring wizard and follow diagram #4 take the positive and negative from each woofer to the terminals on the box then take those and run them to the positive and negative of the amp. You can use 1 positive and 1 negative on the amp for each sub since they are on the same terminal internally.
