Without modification, the SF Power cannot be operated in a bridged mono mode. SF makes an amp for this purpose named the Power 3.

I have been looking for a Power 3 for a couple of years now and have yet to find one. A Power 2 however is readily available and for as little as $1500, so I was thinking if they can be mono blocked, that would be a good way to go.
I'm not sure if I am understanding however, if it can or can't be. I was under the impression pretty much any amp can be hooked up in a bridged mono block fashion.
I have spoken to Chris Johnson before and he wants to sell me the upgrade kit for the Power 2. I don't blame him for that, but that isn't what I am looking for.
There is another option. Instead of bridging, there is paralleling. Essentially, just jumper the inputs together with a xlr or rca splitter and the jumper the outputs (L+ to R+ and L- to R-). This will double the watts and be better for low impedance speakers. Sometimes requires a small (1-2 ohm) resistor between outputs but that's usually for SS amps without output transformers. Might need to change impedance setup on underside. Confirm with Chris at PCX before trying.
