Some Amps that we are looking into getting. (which would you choose?) QSC RMX 2450 - top of our list Crown - not sure which one to go with Crest - again not sure which to use. We are looking for the best quality sound for the buck. What do all you think? Please feel free to comment on any other Amps that would work. Looking for at least 1000 watts asside.. preferably 2 ohms incase we want to go with 4 speakers for the mids/hi's. Thanks in advance.
