XL-844D 8-Inch Dual 4-Ohm Subwoofer | Safe and Sound

The XL-844D is the dual voice coil version of PowerBass’s 8-inch XL subwoofer, giving you deep, controlled bass from a compact footprint plus the wiring flexibility that dual coils bring. Rated at 200W RMS with a 400W maximum, it is a smart choice when boot or under-seat space is tight. At Safe and Sound we have spent over 30 years building bass systems, and the XL-844D is a great-value, flexible way to add proper low end to almost any car.

Why choose the dual voice coil XL-844D?

The XL-844D’s two separate 4-ohm voice coils are its key advantage. You can wire them in parallel for a 2-ohm load or in series for an 8-ohm load, letting you match the subwoofer to your amplifier’s ideal impedance, or combine multiple subs to reach a specific load. If your setup is simpler and you only need a single 4-ohm coil, its sibling the single-coil XL-844 covers that, so it is worth matching the version to how you plan to wire your system.

Compact size, serious bass

PowerBass designed the XL Series for extended low frequency response, so the XL-844D digs deeper than you might expect from an 8-inch driver. A proprietary non-pressed paper cone with a DDC coating delivers smooth, natural bass with low distortion even at high output, while a large-roll Santoprene surround lets the cone move freely for that satisfying low end.

• 8-inch dual 4-ohm subwoofer, 200W RMS / 400W max
• Two 4-ohm voice coils for flexible wiring (2 ohm or 8 ohm)
• Non-pressed paper DDC-coated cone for smooth, low-distortion bass
• Large-roll Santoprene surround
• 2-inch vented BASV voice coil former with Aero-Vent cooling

Built to stay cool, and to last

Bass puts heat through a voice coil, so the XL-844D is built to manage it. A 2-inch vented BASV voice coil former, combined with perimeter and pole Aero-Vent cooling, keeps air circulating to keep temperatures down on long, loud sessions. The non-resonant polycarbonate and glass-fibre turbine-style basket supports dual stack magnets and an extended dome backplate for solid performance, and chrome push terminals ensure strong current transfer from your amplifier. It is happy in both small sealed and ported enclosures, so you can tailor the build to the sound you want.

Key specifications

Professional fitting from Safe and Sound

A dual voice coil subwoofer gives you options, but those options only pay off if the wiring, enclosure and amplifier all work together. Get the box volume, tuning and impedance right and the XL-844D rewards you with clean, deep bass. With more than three decades of car audio and vehicle security experience, Safe and Sound can supply the XL-844D on its own, build or recommend the right enclosure, and wire it to the correct impedance for your amplifier so you get the best possible result.
