Setup and Installation
Proper installation is crucial for the performance and longevity of your amplifier. If you are not experienced with car audio wiring, it is highly recommended to seek professional installation.
Mounting Location
- Choose a dry, well-ventilated location away from direct sunlight and heat sources.
- Ensure sufficient airflow around the amplifier's heatsink to prevent overheating.
- Mount the amplifier securely to a solid surface using the provided hardware.
Wiring Connections
Before making any connections, disconnect the vehicle's negative battery terminal.
- Power (B+): Run a heavy gauge power cable (e.g., 4 AWG or 8 AWG depending on total system power) directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. Install an inline fuse holder within 18 inches (45 cm) of the battery.
- Ground (GND): Connect a heavy gauge ground cable of the same length as the power cable from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote Turn-On (REM): Connect a smaller gauge wire (e.g., 18 AWG) from the amplifier's REM terminal to the remote turn-on output of your head unit. This wire signals the amplifier to turn on and off with the head unit.
- RCA Inputs: Connect RCA cables from your head unit's pre-amp outputs to the amplifier's RCA input jacks. Ensure correct channel matching (Front L/R, Rear L/R).
- Speaker Outputs: Connect your speakers to the amplifier's speaker output terminals. Pay close attention to polarity (+ and -) for each speaker. The ZXX-600.4 can be configured for 4-channel stereo or 2-channel bridged operation. Refer to the amplifier's specific terminal layout for bridging instructions.

Operating Instructions
Once installed, the amplifier requires proper adjustment for optimal sound quality and system protection.
Initial Power-Up
- Double-check all wiring connections for security and correct polarity.
- Ensure the amplifier's gain controls are set to their minimum (fully counter-clockwise) position.
- Reconnect the vehicle's negative battery terminal.
- Turn on your head unit. The Hifonics logo on the amplifier should illuminate, indicating it is powered on.
Gain Adjustment
The gain control matches the amplifier's input sensitivity to the output level of your head unit. It is not a volume control.
- Set your head unit's volume to about 75-80% of its maximum level.
- Slowly increase the amplifier's gain control until you hear distortion, then back it off slightly until the sound is clear.
- Repeat for all channels.
Crossover Settings
The ZXX-600.4 features an electronic crossover. Adjust these settings based on the type of speakers connected to each channel.
- Full Range: For speakers reproducing all frequencies.
- High Pass Filter (HPF): For speakers (e.g., component sets, coaxial speakers) that should not reproduce low bass frequencies. Adjust the frequency knob to cut off frequencies below a certain point (e.g., 80Hz-120Hz).
- Low Pass Filter (LPF): For subwoofers (if bridging channels for a subwoofer). Adjust the frequency knob to cut off frequencies above a certain point (e.g., 80Hz-120Hz).
Maintenance
The Hifonics ZXX-600.4 amplifier is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure its longevity.
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or solvents.
- Ventilation: Ensure that the heatsink fins are free from obstructions to allow for proper heat dissipation.
- Wiring Inspection: Annually inspect all power, ground, remote, and speaker connections for corrosion, fraying, or looseness. Tighten any loose connections.
- Fuse Check: If the amplifier fails to power on, check the inline fuse near the battery and the fuses on the amplifier itself. Replace blown fuses only with the correct rating.
