Jam to Wolfgang Amadeus Phoenix at your next picnic with the Boom Cooler ($900). This party cooler packs a punch with a 1100-watt max 10" woofer, 240-watt dual 6"x 9" 4-way speakers and a 4-channel 600-watt Xplod amp. The Boom cooler is also built with a CDX-GT320 AM/FM radio and a CD player. The only downer? With all the sound gear, there's no room in this insulated box for any consumables and frosty brews.
