Passive subwoofers for spare wheels are the ideal choice for drivers who want powerful bass but also need to save as much space as possible in the trunk. Thanks to their special shape, they can be installed directly into the spare wheel well, where they remain hidden and do not restrict the use of the luggage compartment. As these are passive subwoofers, they do not have a built-in amplifier and require connection to an external amplifier, which gives greater possibilities for fine-tuning and harmonizing the entire audio system. A properly selected passive subwoofer for the spare wheel provides surprisingly deep and powerful bass without sacrificing space in the car. It is a smart solution for anyone who wants high-quality bass while maintaining the full practicality of their vehicle.
