I would agree that the output of the 200 series in not great - it's loud enough in the enclosed MG, but nowhere near what I've achieved in other installs. I've got four 4" speakers (two in the door, and two in the rear side panels) powered by the head unit, and then an active Blaupunkt sub woofer behind the front seat which gives a good punchy bass.
