I have one on each of my Q18s @ 2ohms. Each Q is seeing 1000+rms. I had both Qs hooked up to one and it pushed them pretty good @ 1ohm. Both of my T10001bds are refurbs from HDA (High Desert Audio). So I think the less you would see out of a T10001bd is 1000rms @ 2ohm, 1400rms @ 1ohm, but most put out 1500+rms @ 1ohm.
