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.

The Ground Zero GZTK 165 is a high-performance 165-mm low-midrange driver from the Titanium Series, ideal for building and upgrading high-quality car audio speaker systems. Its 3-ohm design allows for efficient use of available amplifier power, making it particularly appealing for performance-oriented front systems.

For sound conversion, Ground Zero relies on a textured 3D-HQPP diaphragm with a diameter of 122 mm. The robust diaphragm material is combined with a durable rubber surround. In the center, instead of a traditional dust cap, there is a phase plug that specifically enhances reproduction in the midrange.

The GZTK 165 features a 25-mm copper voice coil and a ferrite magnet system. The low-resonance steel basket features Euro-DIN mounting dimensions, making it easy to integrate into numerous vehicle and door panel applications. With an installation depth of 68 mm and a required mounting diameter of 142.5 mm, the available installation space should be checked before installation.

The usable frequency range extends from 50 Hz to 4,000 Hz. With a rated power handling capacity of 80 watts and a maximum of 100 watts, the speaker is suitable for use with appropriately rated power amplifiers as well as for use as part of an actively or passively divided multi-way system.
