PowerBass S-1004D 10" dual 4-ohm car subwoofer

PowerBass 10-inch dual 4-ohm subwoofer

The PowerBass S-1004D is a 10-inch car subwoofer with dual 4-ohm voice coils rated at 550 watts RMS and 1100 watts maximum power. It uses a proprietary DDC coated paper and wool cone with a pressed 4-layer foam surround. The 2-inch vented BASV voice coil former and perimeter aero-vent cooling help manage heat during extended play. A non-resonance stamped steel basket and rubber mounting gasket complete the assembly.

Enclosure and amplifier checks

Verify the available space matches the 9 1/8 inch cutout diameter and 5.2 inch mounting depth before ordering. Confirm your amplifier can deliver appropriate power into the dual 4-ohm configuration which presents a 1.6-ohm test impedance. The subwoofer is optimally designed for both small sealed and ported enclosures, so choose the alignment that suits your listening preference and vehicle space. Ensure the amp wiring can handle the current demand at the chosen impedance.

Build integration

The chrome push terminals simplify secure wire connections without special tools. Dual voice coils allow series or parallel wiring to match your amplifier’s stable load, freeing you from a single impedance option. The 33 Hz to 500 Hz frequency response and 86 dB sensitivity suit bass reinforcement in typical cabin environments. The 116 oz motor structure and 9.5 mm Xmax provide the mechanical headroom needed for clean low-frequency output in compact enclosures.
