Has anyone used a Earthquake T2000w/4 before? Ive never used one of thiere multichannel amps and have kind of been suckered into buying one.. not sure if i am yet... all depends on if i get a response from the seller..who hasnt been responding before... but anyways are they any good will it do its rated power? Im looking for 100rms x4 at 4ohm... it says it will do it..
