Kicker 51PTRTP12

Product Description:

The Kicker 51PTRTP12 is a low-profile, down-firing powered subwoofer enclosure designed to deliver deep, punchy bass while maximizing space in trucks, SUVs, and hatchbacks. It pairs an active 12-inch CompRT shallow-mount subwoofer with a matching 12-inch reFLEX passive radiator inside a heavy-duty, sealed medium-density fiberboard (MDF) cabinet covered in rugged black carpet. Powered by an integrated 500-watt RMS amplifier, this system utilizes a downward-firing orientation that naturally protects the subwoofer cone while allowing heavy cargo to be loaded directly on top of the enclosure without sacrificing sound performance.
