what have people run it down to ohm wise though? Would it handle a 2 ohm bridged?

I have to fosgate he2 the older ones from 03 ish era. They are dv 4ohm i was thinking about wiring them to 1 ohm since my only options are 4 ohm or 1 ohm. At 4ohm bridged right now the output just isnt there. They are in a small sealed enclosure about cubic foot or so each sub. If anyone has any input that would be great. I am waiting on a call back from my box builder to see what kind of idea's he has.
