Sometimes you have to take the party with you and the BoomCooler is the ultimate party machine. At $900 for a stereo in a cooler it damn well better be. Make no mistake, this is one powerful stereo; an 1100 watt 10″ subwoofer, a pair of 240 watt speakers and a 4 channel 600 watt amplifier all by Sony are built in. All that boomboxing leaves no space to cool off any drinks, so you’ll need a regular cooler for that. The BoomCooler is on wheels because it weighs 77 lbs without batteries. It’s basically a massive car stereo in a cooler. There you go.
