With regard to the question of monoblocks vs. bridged stereo amps.
Generally speaking stereo amps do not increase current output when they are bridged into mono. You may see an increased wattage spec but the current output is typically not much higher.
I say generally speaking because there are some amplifiers which, either because they are dual differential or truly balanced or whatnot, will be able to effectively double their current output when bridged into mono. You should research your particular amp and find out.
In most cases I am not a big fan of bridging amps into mono and prefer to bi-amp instead. I had a customer who was using two big 600 wpc. McIntosh amps bridged into mono and we unbridged them for him and set them up as vertically bi-amped stereo amps. He could play _much_ louder and the bass was much deeper. More current - that was the trick.
