Alpine PWE-S8 120W 8" Powered Subwoofer

The Alpine PWE-S8 is a compact powered subwoofer system featuring an 8-inch high-performance quad-coil subwoofer. Despite its small size, it delivers deep, accurate bass with a 120W output. Its dimensions are 3 inches deep, 13.5 inches wide, and 9 inches tall, making it ideal for installation under or behind seats or in tight spaces. Builders needing higher output or larger cone area will not find it here.

120W RMS Output Decides Fit

The single specification that decides whether this is the right part is the 120W RMS output from the integrated amplifier. This power level matches modest cabin volumes and factory or aftermarket head units without requiring a separate amplifier chassis. Systems targeting competition SPL levels or larger enclosures need more power than this unit supplies.

Bundle Adds Full-Range Sound

The bundle adds an Alpine UTE-83BT single-DIN digital media receiver with Bluetooth and 4.25-inch mounting depth, plus a pair of Alpine SXE-1726S 6 1/2-inch 2-way coaxial speakers. Together they provide source, amplification, midrange, and bass in one purchase. Buyers who already own a head unit or component speakers gain duplicate items they cannot use.
