not sure what you mean by it is a mono sub but has two speaker 'OUTPUTS'...mono amp with 2 outputs??...a DVC sub will have two sets of inputs on it if that is what you mean.. two dual 2 subs to a 2 OHM load would be done in a parallel series setup..wire the subs indivually in parallel then wire the two of them together in series that should give you a 2 ohm load on your amp..if you amp is mono block it should just have a + and a - output on it...you shouldnt have to bridge a mono amp...i am confused by your opening statement..here is a pick of your wiring set up though..
