Ok,,, I am lookin around all sorts of sites that sell amps and for the specs i never see ex. 200watts x 1 rms (2ohms) for any amp that is 2 or more channels. But... it often says ex. 100wattsx1rms(4ohms). so can a 2 channel amp be bridged to one channel and run at 2 ohms?

Another side quetion for yah,,,,, if i get one of those 50x4 pioneer decks can i bridge any of those channels?
