This manual provides installation and configuration instructions for the Ground Zero Titanium Series GZTC 165.3X-II 3-way component loudspeaker system. Key features include Klippel-optimized components, 3-ohm impedance, and a passive crossover with adjustable levels.
Safety instructions
- Keep all parts and packaging away from children and pets to avoid suffocation.
- Avoid prolonged exposure to high volume levels (over 85 dB) to prevent hearing damage.
- Do not operate at levels that hinder the perception of traffic noises.
General installation notes
- Never drill into the vehicle's gas tank, brake lines, wiring, or other critical parts.
- Avoid routing cables over sharp edges.
- Keep signal and speaker cables away from antenna electronics and power supply wiring to prevent interference.
- Use adequately dimensioned wires for connection.
Crossover adjustment
The crossover allows for individual sound tuning:
- Tweeter level: Use the jumper to select between -2 dB, 0 dB, or +2 dB.
- Midrange cut-off: Use the jumper to select between Low (linear frequency response) or High (increased upper midrange frequency response).
Wiring
Connect the system according to the following terminal labels:
- IN: Signal input from head unit or amplifier.
- TW OUT: Tweeter connection.
- MID OUT: Midrange connection.
- WF OUT: Kickwoofer connection.
