The PSS-22WRA is a weather resistant, direct fit sound system for Jeep Wrangler JK Unlimited models with automatic transmission and without the factory-equipped Alpine amplified sound system (the factory-equipped Alpine amplified system is identified by an Alpine logo on the subwoofer in the back rear-right). The 1200-watt, 9-speaker system consists of an under-seat 10 enclosed subwoofer, two 6.5 2-way convertible component/coaxial speaker sets, a 4-channel compact amplifier, a mono compact amplifier and a remote bass knob, plus vehicle-specific harnesses and mounting brackets Whether your Jeep Wrangler JK Unlimited has factory component or coaxial speakers, the PSS-22WRA will fit in your vehicle. Thanks to the included adapters, the speakers can be configured as component or coaxial layouts. Alpine s exclusive Dynamic Peak Power (DPP) amplifier technology and the 10 under-seat subwoofer enclosure deliver incredible sound performance (600W RMS/1200W DPP). The PSS-22WRA loads and disperses lower frequency sound from the passenger s foot well area, for maximized bass extension throughout the Jeep that sounds great with the top on or off. Caught with the top in inclement weather? Not to worry. The PSS-22WRA can withstand rain and dust. The subwoofer uses rust resistant hardware and can handle water from off-roading adventures or a quick rinse down. The PSS-22WRA is compatible with any Alpine Restyle Jeep Wrangler dash system, the Jeep factory base radio, or other aftermarket radio. The PSS-22WRA is authorized to be Sold By and Shipped From .
