There are times when your favorite programming deserves a different setting than your car. Listen to SiriusXM stations in your home, the office or even in your backyard. A concealed handle lets you take this elegant system anywhere. You will enjoy class-leading sound quality with full audio range provided by a 2.1 system with separate tweeters, mid-range speakers and a powerful subwoofer that delivers hard-hitting bass response. Simply plug into an available AC outlet or listen anywhere with batteries (requires 8 D-cell batteries, sold separately). You can operate both the Portable Speaker Dock and your Satellite Radio using the included remote control. You can even listen privately using the headphone jack and connect MP3 players and other audio devices via the aux in jack (aux in cable sold separately).
