Introduction
Thank you for choosing a great GROUND ZERO product! We hope you will enjoy
this product from the NUCLEAR series. This owner´s manual contains information
you need to use this product. Please read it carefully in order to achieve
the best possible result. Your car audio specialist or our customer support
will answer further questions about the product and its use.
Subwoofers are an important part of your car audio system. Please keep in
mind, however, that they can only achieve their full performance if all other
components of the entire system are carefully coordinated with one another.
It is therefore recommended consulting a car audio specialist dealer or
workshop for the assembly of the system and its installation and sound
adjustments.
Series – Ultimate Performance
With several particular features of the High End PLUTONIUM line, GROUND ZERO managed to position the NUCLEAR line products at a lower price level. Nevertheless, the amazingly sounding speakers are partly “Made in Germany”. The subwoofers are predestined for high level audio setups as well as for SPL competition while massive multi-channel and impressively powerful mono amplifiers deliver excellent performance.
General installation note
- Never drill a hole to the vehicle´s gas tank or brake lines, to wirings or any other important vehicle parts!
- Never pass wires over sharp edges or vehicle parts to avoid any kind of damage
- Keep the wiring away from the antenna and electronic devices contributing to radio reception
- Lay the power supply wiring always separated from speaker wiring to avoid disturbance
- Use adequately dimensioned power and speaker wires to connect the component

Respect the Music
Listening to music can be emotional, impressive, relaxing or enjoyable. At that, it doesn´t really matter what kind of music is the personal favorite, whether it´s Instrumental, Jazz, Electro, Latin, Classic, Rock or any other music direction. However, audio reproduction quality at each desired volume is elementary. Some music styles require higher levels while others prefer the soft tones. GROUND ZERO considers all the different wishes of customers during the development of new products. Along with this, the target is to create the most realistic sound, to transfer the soul of the music and the intention of the performer. Summarized to one phrase: RESPECT THE MUSIC!components to a local recycling facility at the end of their practical use.
