Product Overview
The Hifonics HEW12D4S ELITE is a 12-inch shallow-mount subwoofer for adding bass to a mobile car audio system. Its 8.1 cm mounting depth helps preserve cargo space, and its dual 4-ohm voice coils are designed for sealed-enclosure installations.
Key Features & Benefits
- Shallow-mount design: The 8.1 cm mounting depth can help retain more room around the installation area.
- Heat management: High-temperature voice coils and a vented aluminum former help dissipate heat.
- Woven fiber cone: The lightweight cone and dust cap support faster response while providing strength.
- UV-treated foam surround: The surround resists sun fading while remaining flexible.
- Poly-cotton spider: Its design resists softening and sagging over time to support high-power handling with minimal distortion.

Power-matched options for one subwoofer or one complete loaded enclosure. We aim to include same-brand choices when their ratings qualify.
Loading amplifier suggestions…
Suggestions use 75–125% of the subwoofer’s RMS rating at the wiring load shown. Check wiring, enclosure needs, electrical capacity and installation space. Set gain and filters correctly to avoid overpowering the subwoofer. Buying more than one subwoofer changes the match.
