PowerBass S1204 12" S Series 4 Ohm 600W car speaker

12-inch S-Series subwoofer

The PowerBass S1204 is a 12-inch S-Series subwoofer built for car audio enthusiasts who want hard-hitting bass without a premium price. It handles 600 W peak power and uses a single 4-ohm voice coil for straightforward wiring. The design targets drivers seeking loud, low-distortion output in a compact enclosure.

Upgrade from smaller cones

Moving up from a 6.5-inch or 10-inch driver adds cone area and a larger magnet structure, so the jump is worth it when you need more volume and deeper extension in a sealed or ported box. The 4-layer wool/paper cone and large-roll foam surround keep distortion low at higher excursion. Buyers who need multiple subwoofers for extreme SPL will find a single unit limiting.

Straightforward enclosure install

The stamped steel basket with non-resonant finish bolts into standard 12-inch cutouts, and the single 4-ohm coil simplifies amplifier matching. A 2-inch BASV voice-coil former handles thermal loads during extended play. Installers must seal the enclosure properly; air leaks are the most common cause of reduced output and mechanical noise.
