Factory speakers rarely have much to say below the midrange, and this is a way to fix that without giving up cab space. Trail Grid Pro builds a fitted subwoofer enclosure for the Tundra CrewMax and ships it with an Alpine S2-W10D4 10 inch subwoofer already installed. The sub is a dual 4 ohm voice coil design rated at 600 watts RMS and 1,800 watts peak, so it has headroom to spare for a clean, controlled low end.
The enclosure is cut from MDF and finished in a LineX coating, which Trail Grid Pro chose for durability and water resistance. It holds 0.812 cubic feet of air space and measures 26.625 inches wide, 18.75 inches tall and 7.375 inches deep. It sits behind the driver-side rear seat, which leaves the passenger-side rear seat storage free for gear and tools. Trail Grid Pro designs and assembles it at its Frederick, Maryland headquarters.
