Wiring wizard & port computer

Use our wiring wizard for simple wiring of speakers and subwoofers! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The data sheet shows you which connection the respective amplifier is designed for!

Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

With the Ground Zero GZ SUB-AMP 300, passive subwoofer enclosures can be quickly and easily transformed into powerful active subwoofers. This compact mono amplifier module was specifically designed for many Ground Zero subwoofer enclosures and replaces the existing speaker terminal plate. Thanks to modern Class D technology, it offers high efficiency, powerful bass reproduction, and a space-saving design. With its integrated low-pass filter, variable bass boost, and high-level input with automatic power-on function, the module is suitable for both retrofits and OEM audio systems without RCA outputs. A wired bass remote control allows for convenient adjustment of the bass level directly from the driver’s seat.
