before i got my Massive Audio CK6V i was looking into the Morel Maximo 6. didn't find too many reviews about the Morel's so i went with the Massive's all im waiting for to install the Massive's are the mdf spacer rings i ordered. as for the amps the ones i got my eye on are the MB Quart ONX4.125 and the Massive Audio NX4
