memphis is our biggest seller at work. and mojos are a very popular sub, especially in 3.5 to 5 cubes @34-36hz and a 1000d on them. they can handle twice that easily, but they don't need it in the right box. and to top that off, 1kwrms is all they are rated for.prob 36 htz on the mojos as i was told after mine to prevent bottoming out because of the Fs but im sure mrray will chime in he seems alot more knowledgable than me on this topic. My mojo seems hungry for more power off my mc1000d
