Compact power for a richer car audio experience

Upgrade your in-car sound with the Pioneer TS-WX400DA, a compact amplified subwoofer designed to integrate smoothly with a wide range of systems. Its slim footprint is crafted to fit under seats or in tight spaces, so you can add deep, musical bass without sacrificing cabin room. The combination of a built-in 250W Class D amplifier and a precise, responsive driver delivers bass that feels fast, controlled, and engaging—helping you hear the energy and nuance in your favorite tracks.

Two bass modes to tailor your listening experience

The TS-WX400DA offers two selectable Bass Modes to match genre and mood. Deep mode emphasizes rich, low-end warmth ideal for classic rock, jazz, and country, while Dynamic mode brings a punchier, more energetic bass for EDM, hip-hop, and rock. This flexibility makes it easy to adapt the sound to what you’re listening to without changing other components.

Power, efficiency, and easy installation

With a maximum power handling of 250 watts and continuous power of 100 watts, this subwoofer provides noticeable impact without excessive draw on your electrical system. The built-in Class D amplifier is designed for efficiency and cooler operation, which helps when space is limited. The enclosure is included, simplifying mounting decisions and enabling a clean, professional look in a variety of vehicle layouts.

Easy integration with most radios

Designed to work with most factory or aftermarket radios, the TS-WX400DA uses high-level input to minimize wiring headaches and maximize compatibility. This makes it a practical choice for upgrading the bass in many vehicles, from compact sedans to larger SUVs.

Real-life listening benefits
