Im looking into replacing my little eclipse 4 channel amp that im running my front seps (ID csx64s). I am trying to decide what to use, either a ARC 2100cxl running 100w per channel or 2 ARC2050s mono at 230w per channel. The seperates are rated at 150w. price isnt an issue because 1 2100 will cost the same as 2 2050s that i found.
