Yes, this stealth subwoofer is designed to fit inside 15-inch or larger spare tires across all vehicle models. The unit mounts directly into the center of your spare tire hub using the included long mounting bolt, so it sits completely hidden while you retain 100% of your trunk space for cargo.
The Tank 300 plug-and-play SKU includes a vehicle-specific wiring harness pre-configured for GWM Tank 300 models, ensuring seamless integration with your factory radio without any cutting or splicing. The Other Vehicles variant is designed for vehicles with sufficient backup tire space but may require different harness routing depending on your model's wiring layout. We recommend confirming your specific vehicle model when ordering to ensure you receive the correct harness configuration.
Installation typically takes 1–2 hours and requires only basic hand tools to remove your spare tire and tighten the mounting bolt. The plug-and-play T-Harness connects directly to your factory radio without any cutting or splicing, so no electrical expertise is needed. All mounting hardware and the wired remote are included in the package.
No — the plug-and-play installation is 100% non-destructive and preserves your factory warranty. The vehicle-specific T-Harness connects between your factory radio and original wiring without any permanent modifications, so your vehicle remains in its original electrical state.
The subwoofer features a pro-grade Aluminum-Zinc alloy chassis that is precision-molded for superior heat dissipation and zero resonance during high-volume playback. This durable construction ensures reliable performance while the unit remains hidden inside your spare tire.
Yes — the included wired remote bass control lets you adjust volume and bass levels on the fly. The subwoofer also features fully adjustable Gain, Crossover, and Phase controls that synchronize the bass seamlessly with your factory speakers for a balanced sound profile tailored to your preference.
The package includes the subwoofer unit, a wired remote bass control, a vehicle-specific wiring harness, a mounting hardware kit with the long mounting bolt, and a subwoofer protection bracket. Everything you need for a complete plug-and-play installation is included.
