Product Overview
Build a high-output car audio system around the SoundQubed HDX3.2-12, a 12-inch subwoofer rated for 2,500 watts RMS and 5,000 watts peak. Its 3-inch voice coil, 300 oz magnet, and 15 mm (±) Xmax are designed for demanding bass builds.
Choose the Dual 1 Ohm (D1) or Dual 2 Ohm (D2) version to match your amplifier’s stable impedance options and planned wiring.
Key Features & Benefits
- Power handling: The 2,500 W RMS rating suits high-output amplifier systems when the amplifier is matched to the wired load.
- Extended excursion: 15 mm (±) Xmax and 35 mm (±) Xmech provide the stated linear and mechanical travel figures for bass-focused builds.
- 3-inch voice coil: The 50 mm coil length supports the subwoofer’s high-power design.
- Two dual-voice-coil options: D1 and D2 configurations offer different final impedance choices through series or parallel wiring.
- Enclosure options: Use the supplied volume ranges to plan either a sealed or ported enclosure.
- Low resonance frequency: Fs is 28.8 Hz for D1 and 28.4 Hz for D2.

Why Choose This Product?
The HDX3.2-12 gives you two voice-coil configurations to consider when planning a high-power mono amplifier system. Its stated power rating, excursion figures, and Thiele-Small parameters provide useful details for choosing equipment and designing an enclosure around your build.
The supplied guidance pairs a sealed enclosure with tighter, accurate bass and a ported enclosure with SPL output and low-frequency extension. The recommended ported tuning range is 28–34 Hz.
Installation & Compatibility Notes
The source recommends pairing the subwoofer with a mono block amplifier capable of delivering 2,500 W RMS or more at the final wired impedance. Confirm your amplifier’s stable load before choosing D1 or D2.
- D1 wiring: Parallel wiring gives a 0.5Ω final load; series wiring gives a 2Ω final load.
- D2 wiring: Parallel wiring gives a 1Ω final load; series wiring gives a 4Ω final load.
- Enclosure planning: The recommended sealed volume is 1.25–2.0 ft³. The recommended ported volume is 1.75–2.75 ft³.
- Mounting dimensions: Use the model-specific measurements in the table above when checking enclosure clearance.
Frequently Asked Questions
What amplifier power is recommended for the HDX3.2-12?
The supplied recommendation is a mono block amplifier rated at 2,500 W RMS or more at the wired impedance. Check amplifier stability at your selected final load.
What final impedance can I get with D1 and D2?
D1 can be wired for 0.5Ω in parallel or 2Ω in series. D2 can be wired for 1Ω in parallel or 4Ω in series.
What enclosure volume should I plan for?
Use 1.25–2.0 ft³ for a sealed enclosure or 1.75–2.75 ft³ for a ported enclosure. The supplied ported tuning recommendation is 28–34 Hz.
How do the D1 and D2 versions differ in resonance frequency?
The D1 model has an Fs of 28.8 Hz; the D2 model has an Fs of 28.4 Hz.
Is the HDX3.2-12 intended only for competition systems?
The supplied product information describes it for both daily and competition builds, including SPL and SQL systems.

Recommended Monoblock Amplifiers
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.
