Alpine
A complete car audio upgrade kit with a compact powered 8-inch subwoofer, 6.5-inch and 6x9-inch coaxial speakers
This Alpine bundle combines a compact powered 8-inch subwoofer with two pairs of coaxial speakers for a complete car-audio upgrade. The PWE-S8 subwoofer integrates a 120W amplifier in a shallow 3-inch-deep enclosure that fits under or behind seats. The SXE-1726S 6 1/2-inch and SXE-6926S 6x9-inch speakers handle 40W and 45W RMS respectively for clear midrange and treble. Together they deliver full-range sound without requiring a separate amplifier rack.
This bundle suits drivers who want deeper bass and clearer vocals from a single purchase that includes matching speakers and a self-powered subwoofer. Installers will appreciate the subwoofer's adjustable phase, gain, low-pass crossover and remote level control for quick tuning. It is not for buyers who need more storage space than the compact enclosure allows, builders who require a second subwoofer for higher output, or systems that demand separate component speakers with external crossovers.
The subwoofer's 120W amplifier and high-excursion 8-inch driver provide solid low-frequency impact for most music genres at moderate volumes. The SXE-1726S speakers cover 60Hz-20kHz at 40W RMS with 220W peak headroom, while the SXE-6926S speakers extend down to 40Hz at 45W RMS with 280W peak headroom. This combination comfortably handles typical cabin listening levels, but runs out of headroom for competition-grade SPL or very large vehicles needing higher output.

Choose an amplifier or head unit that delivers roughly 40W RMS per channel for the 6.5-inch pair and 45W RMS per channel for the 6x9-inch pair to match their continuous power handling.
Yes, the PWE-S8 accepts speaker-level inputs so it can connect directly to factory speaker wires without needing RCA pre-outs.
Play a test tone sweep from 40 Hz to 20 kHz; the 6x9s should reproduce down to 40 Hz, the 6.5-inch speakers to 60 Hz, and the subwoofer should output strong bass around 80-120 Hz with its 120W amplifier.
