DIY Bluetooth Speaker Kit

I recently posted this beauty of a wireless radio/speaker constructed using a customizable audio kit designed specifically for an array of DIY projects. Furni sells the same innards inside their fancy Kendall, a pair of 5 watt class "D" audio amplifier, two  2" magnetically shielded speakers, with full Bluetooth v2.0, and everything to power up the system. For a few dollars more you can even download the plans to build a cardboard boombox shown above using the speaker kit.
