IKEA Symfonisk Gen2 Amp Modification Guide – A Much Cheaper Sonos Amp

We're back with a new one - Sonos and Ikea have updated the Symfonisk for Gen2. At an absolute minimum you need some binding posts, a Symfonisk Speaker and a ceiling speaker for each output location. If you want to follow this guide and make your own enclosure, throwing in the cost of a decent 3D printer and filament, is still 29% less expensive at about $900. A video guide for Gen2 will be coming very soon. The amplifier on the Symfonisk speaker is the TI TPA3116D2, a two speaker amplifier allowing 30 watts per channel in stereo mode, or 100 watts in a bridged mono mode. Just like on Gen1, we need a jumper across the Left and Right DAC outputs, to cut the traces of the Left +/- pins to the amp, and then to bridge the Left channel amp pins to ground. Most binding posts use the same terminal connector as the large connector on the Symfonisk. Red/Black is your new positive wire, and Blue/White is your new negative wire.
