Kicker builds their Solo-Baric® subwoofers for one purpose: to deliver truly huge, supremely accurate bass. The 44L7S154 Solo-Baric L7S™ 15″ component subwoofer handles up to 1000 watts RMS, enough power to fill any vehicle. Its innovative square cone moves much more air than a conventional 15″ round cone, and this sub’s made to take anything you can dish out.
