Setup and Installation
1. Mounting Location
Choose a mounting location that is dry, well-ventilated, and away from direct heat sources. Ensure sufficient airflow around the amplifier for proper cooling. Common locations include under seats, in the trunk, or behind rear seats. The amplifier dimensions are approximately 21 x 11.4 x 4 inches.
2. Wiring Connections
Refer to Figure 7 for the power and speaker terminal panel, and Figure 6 for the input/output panel.
- Power (BATT +12V): Connect a direct wire from the positive terminal of your vehicle's battery to the +12V terminal on the amplifier. Use a fuse holder with an appropriate fuse (not included) as close to the battery as possible.
- Ground (GND): Connect a short wire (less than 3 feet) from the GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Remote (REM): Connect this terminal to the remote turn-on output of your head unit. This will turn the amplifier on and off with your car's audio system.
- RCA Inputs (CH1/CH2, CH3/CH4): Connect RCA cables from your head unit's pre-amp outputs to the corresponding RCA input jacks on the amplifier.
- Speaker Outputs: Connect your speakers to the speaker output terminals. Ensure correct polarity (+ to + and - to -). For bridged operation, refer to the bridging diagram usually found on the amplifier itself or in a more detailed wiring diagram.
3. Initial Settings
- Level (Gain) Control: Start with the gain control set to minimum. Gradually increase it until the desired volume is achieved without distortion.
- Crossover (X-OVER):
- HPF (High Pass Filter): Allows frequencies above the set point to pass. Useful for full-range speakers.
- LPF (Low Pass Filter): Allows frequencies below the set point to pass. Useful for subwoofers.
- FULL: Allows all frequencies to pass.
- Bass Boost: Use this control sparingly to enhance bass frequencies. Excessive bass boost can lead to distortion and speaker damage.
Operating the Amplifier
Power Indicators
- Green LED: Indicates the amplifier is powered on and operating normally.
- Red LED (Protect): Indicates the amplifier has entered protection mode due to an issue such as overheating, short circuit, or low voltage. Turn off your audio system and vehicle, then check all connections and allow the amplifier to cool down before restarting.
RGB LED Lighting System
The Tarantula amplifier features a customizable RGB LED lighting system. A simple press of the end panel mounted switch (refer to Figure 7, "LED MODE" button) changes the color to one of several presets, slow-motion color change, or rapid flashing random color. For more custom installs, a single color can be selected during slow-motion color change.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the amplifier's exterior. Do not use harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the amplifier's cooling fins are free from dust and debris to maintain proper heat dissipation. Periodically check for obstructions.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power (Green LED Off) | Blown fuse, loose power/ground/remote wire, no remote signal from head unit. | Check and replace fuses. Verify all power, ground, and remote connections are secure. Test remote wire for 12V signal when head unit is on. |
| Protection Mode (Red LED On) | Overheating, short circuit in speaker wiring, impedance too low, low voltage. | Allow amplifier to cool. Check speaker wires for shorts (bare wire touching chassis or other wires). Ensure speaker impedance matches amplifier's capabilities. Check vehicle's battery voltage. |
| No Sound Output | RCA cables disconnected/damaged, gain set too low, speaker wires disconnected, head unit issue. | Check RCA connections. Increase gain setting. Verify speaker wire connections. Test head unit with another amplifier or speakers. |
| Distorted Sound | Gain set too high, improper crossover settings, poor ground connection, damaged speakers. | Reduce gain. Adjust crossover settings. Ensure ground connection is solid. Inspect speakers for damage. |
| Engine Noise/Whine | Poor grounding, RCA cables too close to power wires, faulty ground loop. | Improve ground connection. Reroute RCA cables away from power wires. Install a ground loop isolator if necessary. |
