Mono blocks are generally used as the term of running 1 powerful sub (1chan bridged mode)

But if your going to use a 2/1channel mono block then you will only need to run 1 pair of RCAs from the HU (sub-out) then connect these two RCAs to your amp input. Then hook up your output channels 1 & 2 to each of your subs (2).

If your planning to run and utilise your dual voice coils setup on both subs then you will need a min of 800wrms per channel.

So if 1 sub is 450rms @ 4ohms.. Then you use DVC to lets say 2ohms then your new total will be approx 850wrms per sub (cant remember the exact formula). So in saying this you will need at least a min 800wrms amp to run 1 sub.
