Summary: I am running an Alpine Type R on this, plus just one set of JL components in my 350Z and let me tell you, this thing is unbelieabable. Its way smaller than it looks and the power that comes out is amazing. Im thinking of buying another set of components to fully use all of its power because IT HAS MORE!! One thing though, i cant figure out why if i only plug in the front input, the rear and sub outputs sound? how can i have Bass with no sub input connected??
