Default anybody hacked insignia ns-bt400 amped speaker yet?

bought one as it seemed like a bargain. blue tooth connectivity and external audio in for $30 at the big blue box.

specs say 2wpc for left and right and 12w for shared sub. it runs off a 12v 2a wallwort so im guessing this has got to be some kind of tripath based amp. i cant get mine apart though without exerting some prying force despite removing the only visible screws on the thing. i dont want to break it.

anybody cracked one open yet?

if theres space to add batteries this would be an awesome little device as it doesnt sound half bad even via bluetooth.

It could just be conventional linear amp chips. The sub could be driven bridged, or use a special low impedance driver to suck more watts from less volts.

You'll just have to open it up and see.
