W8T4-S2 + KTA-30MW 8-Inch Subwoofer and Mono Amp Combo

Build a compact bass setup around the W8T4-S2 8-inch shallow-mount subwoofer. Its 2-ohm single voice coil and 2.5-inch mounting depth suit tight placements behind a seat or in a motorcycle saddlebag, while a 7-inch cutout defines the enclosure opening. The bundle includes the KTA-30MW mono amplifier as an added component for powering the subwoofer. The subwoofer is rated for 250W RMS (CEA), 500W program, and 1,000W peak; the amplifier is rated 300W RMS x 1 and 600W x 1 peak at 2 or 4 ohms. The amplifier's RMS rating exceeds the subwoofer's 250W RMS CEA rating, so set gain conservatively for this pairing. An IP66 weather-resistance rating, compact chassis, and waterproof connector suit exposed vehicle installations, including side-by-sides, boats, open-top vehicles, and motorcycle saddlebags. Speaker-level or low-level inputs, selectable two- or four-channel input, variable gain, and a 50-400Hz low-pass filter help connect it with a factory or aftermarket head unit. The amplifier measures 9-3/16 by 1-5/8 by 3-3/4 inches and fits small spaces such as under a dash or inside a glove compartment.
