Common questions about manuals, registration, and support for this brand.
For high-output amplifiers like the Zero series, it is strongly recommended to upgrade the vehicle's electrical system. This includes using a high-output alternator and dedicated AGM or Lithium batteries (e.g., adequate Ah and CCA ratings) to prevent voltage drops below 12V, which can damage the equipment.
The gain control matches the amplifier's input sensitivity to the source unit's signal voltage (typically 0.2V to 6V or 5V). It is not a volume knob. Incorrectly setting the gain too high can cause clipping, overheating, and speaker damage.
Generally, burnt voice coils or damage resulting from clipping, distortion, or insufficient electrical supply are not covered under the limited manufacturing warranty. Warranty claims typically cover defects in materials and workmanship.
New subwoofers should be played at moderate volumes for the first few weeks of use. This allows the suspension (spider and surround) to loosen up naturally, ensuring optimal performance and longevity before applying full power.
