Alphasonik AS100A 10-inch Down-Firing Subwoofer with Built-in Amplifier – Slim, Tight-Space Car Audio

Compact, Powerful Bass for Tight Spaces

The Alphasonik AS100A reimagines what a small car sub can do. This 10-inch, shallow-down firing design pairs a built-in 400 W RMS amplifier with a peak output up to 1200 W to deliver crisp, punchy bass without hogging your trunk or hatch. The sealed, down-firing enclosure helps keep bass tight and controlled, even when the volume climbs.

In practice, the AS100A sits just where you need it—under seats, in a compact trunk nook, or behind a rear panel—leaving more room for cargo while still delivering impactful low end. The final impedance is 4 ohms and the system sensitivity around 92 dB, which translates to efficient response with a broad range of signals.
