Original Product Details and Specifications

If you want hard-hitting bass from a compact subwoofer that still gives you real power handling and strong low-end performance, the SoundQubed HDX 8 is built for that kind of setup. This 8" subwoofer is a great fit for builds where space matters but output still needs to be serious. Whether you are upgrading a car, truck, UTV, or another custom audio setup, the HDX 8 is designed to deliver strong bass with the durability needed for daily use.

The HDX 8 is rated at 850 watts RMS and 1700 watts peak power, making it a strong option if you are shopping for an 8" car subwoofer that can handle real amplifier power. It is available in dual 2 ohm and dual 4 ohm versions, giving you more flexibility when wiring your system. SoundQubed also lists a 2.5" coil diameter, 125 oz magnet, 36 mm coil length, 82.1 dB sensitivity, and 12 mm Xmax for the HDX 8 model.

Box flexibility is another reason this sub works well in a wide range of builds. The recommended sealed enclosure volume for the HDX 8 is 0.35 to 0.75 cubic feet, while the recommended ported enclosure volume is 1.0 to 1.5 cubic feet. That gives you room to build for tighter, cleaner bass or go after more output depending on the kind of response you want from your system.

If you are looking for a SoundQubed 8" subwoofer, HDX 8 sub, compact high-power subwoofer, or dual voice coil 8" sub for a serious bass build, this one checks the right boxes. It gives you strong RMS power handling, flexible impedance options, solid excursion, and useful enclosure recommendations for real-world performance.
