i own a performance teknique ICBM 772 and its rated at 125w x2. i was just wondering if anyone has used this amp or anything. it has a pretty low thd, and i dont know if it is made well or anything (i got it for like 140$) is it underrated or over rated, and is it comparable to any good amp like us acoustics or jl. cause if its a real good amp, ill just keep it and get a second 2channel amp for the rear speakers... otherwise im ditching it and getting a jl 300.4
