Z3 Roadster
BMW Z3 Model 80S
The Model 80S subwoofer system features an 8" subwoofer in a sealed enclosure designed for the Alumapro Alusonic 8, a high-quality subwoofer capable of producing some serious bass. The enclosure installs in the factory subwoofer (or storage compartment) location in between the seats. The Model 80S offers incredible bass, great power handling, and smooth frequency response.
BMW Z3 Model 68S
The Model 68 is a sealed enclosure designed specifically for the included 6"x8" long-throw, shallow-mount subwoofer. The Model 68 fits entirely within the space occupied by the factory subwoofer (or storage compartment) and completely maintains the stock look of the vehicle.
