Active spare-wheel subwoofers are a clever and space-saving way to add powerful bass to your car without losing trunk space. Thanks to their special design they are installed directly into the spare wheel well, so they remain perfectly hidden while significantly improving the overall audio performance. These subwoofers have built-in amplifiers, so there's no need to buy additional equipment and installation is very simple. Yet they can deliver a powerful and clean bass foundation that regular speakers cannot handle. An active spare-wheel subwoofer is an ideal choice for drivers who want quality bass, easy installation, and maximum preservation of luggage space.
