If you're not a commuter, then you probably spend a lot of time at home. KICKER got you covered there, too, with their iK500 “iKICK” Docking System. This thing has a genuine reflex subwoofer for superior bass and sound and runs in the neighborhoold of $249.
Both of these fine products can be found at kicker.com, target.com, circuitcity.com, homedepot.com, crutchfield.com, all Fry’s Electronics stores, and any Authorized KICKER Car Audio Dealer.
