About: Sundown Audio Z8 Z-Series 8" 2000W RMS Car Subwoofer
Don’t let the size fool you — the Z8 Series 8” subwoofer is built to perform well beyond expectations. With an incredible 2000 watts RMS and 4000 watts peak power handling, this compact beast is ready to drop low, hit hard, and take a beating — all while maintaining control and clarity. Designed for high-output systems with limited space, the Z8 offers the same elite-level engineering found in our larger Z Series drivers, packed into an 8-inch frame.
This sub is built around a black aluminum 2.75" 4-layer round-winding voice coil with a massive 30mm Xmax, giving it incredible excursion and power handling for its size. Every component is engineered for airflow and cooling: from the optimized high-velocity pole vent to the cast-aluminum vented frame spacer ring and heavily vented magnetic gap. Add in stitched XL tinsel leads, a Mega-Roll v.2 surround, custom spider packs, and a large aluminum Faraday ring, and you’ve got a sub that’s made for real-world abuse and long-term performance.
Designed specifically for ported enclosures (sealed not recommended), the Z8 thrives in a 1.0 cu. ft. net enclosure tuned to 32Hz. Whether you’re building a powerhouse daily driver or squeezing competition-level performance into a tight space, the Z8 delivers big bass in a small footprint — no compromises.
