What amp would you use for sub duty? The specs for the 3000 are what I want (approx 850 watts x2 @ 4 Ohms) with extension to 10 Hz.I purchased a Inuke 6000 with DSP a few months ago. It was a decent amp but I don't think it put out half of the inflated peak power specs that Behringer is posting. I returned it after three weeks.I would consider it an okay amp for running a set of mains. But for powering a serious sub....no way.
