Hi. I'm recently looking for an amp for my center speaker, axiom vp180, which is rated at 4ohm. I was considering an old 2b-lp or 3b and running them in bridged mode, so that them can power match my 4b3 for LR speakers. However, I can't find any information whether these amps are able to drive 4ohm speakers in bridged mode. If they do, what will the power rating for 4ohm?
