not really wanting to read a full page of comments but yes, liquid cooling is possible, but for the overclocking of the amp... i would say no, in the way of overclocking a computer. now you could upgrade some things and mod the internals but an amp can only push so hard until it clips or you run out of power supplying it which would cause clipping/distortion. sorry if this was said but im too lazy to read a full page of comments at the moment.
