With a compact 4 1/2" mounting depth and a powerful 5 1/2" magnet, this enclosure delivers big, hard-hitting sound while keeping your setup low-profile. Constructed from 5/8" high-density MDF, it offers rugged durability and consistent acoustic performance on every American road. Wrapped in a tough trunk-liner carpet, it resists wear, spills, and fading while maintaining a clean, factory-inspired look that complements your truck interior.


Sealed with premium Titebond silicone and reinforced with wood glue, this enclosure locks in every vibration for distortion-free, powerful bass. A single binding post terminal makes installation quick, secure, and professional-grade.

Built tough for real-world driving, it stays reliable through bumps, turns, and long miles while keeping your bass punchy and consistent.

A car subwoofer with a shallow-mount design and comes with a lot of impressive features, the JL Audio 10TW3-D4 is the perfect upgrade for your car's factory subs. This 10-inch subwoofer has the ability to put in some heart-pounding bass and would not need too much space to be installed inside your vehicle.
It has a mica-filled polypropylene cone and a rubber surround, which gives the subwoofer the needed rigidity and durability to withstand the effects of extended usage at high volume levels while being able to produce an accurate bass response with only minimal distortion.


It uses JL Audio's DMA-optimized motor design, which helps reduce the distortion while being able to produce a clean and punchy low-frequency performance. It also has JL Audio's famous Concentric Tube Suspension, which significantly improves the subwoofer's excursion, allowing for more air pressure, and resulting in louder and better bass performance.
The JL Audio 10TW3-D4 has a power output of 400 Watts RMS and can reach up to 800 Watts of peak power. It has a frequency response of 24 up to 200 Hz and a sensitivity rate of 82.1 dB, which allows the subwoofer to go really deep and loud with less distortion
