Wiring Connections
Refer to the diagrams below for proper wiring of your STINGER Audio amplifiers. Always ensure correct polarity and secure connections.
- Power (0/1 Gauge for MT20001, 4 Gauge for MT-600.4): Connect to the vehicle's battery through an appropriate fuse holder.
- Ground: Connect to a clean, unpainted metal surface on the vehicle chassis.
- Remote Turn-On: Connect to the head unit's remote output.
- RCA Inputs: Connect to the head unit's RCA outputs.
- Speaker Outputs (8 Gauge for MT20001, 12 AWG for MT-600.4): Connect to your speakers or subwoofers. Ensure correct impedance matching.
Remote Bass Control (MT20001)

The included remote bass control allows you to adjust the subwoofer output level directly from your listening position. Connect the remote control cable to the "REMOTE" port on the MT20001 amplifier.
Operating Instructions
Once installed, configure your amplifiers for optimal sound.
Gain Adjustment
Set the gain control to match the output voltage of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly. This is not a volume control.
Crossover Settings (MT20001)
- LPF (Low Pass Filter): Adjust to filter out high frequencies from the subwoofer, typically between 40Hz and 180Hz.
- Subsonic Filter: Filters out extremely low, inaudible frequencies that can damage subwoofers, typically set between 30Hz and 80Hz.
- Bass Boost: Provides an adjustable bass enhancement, typically 0dB to 12dB. Use sparingly to avoid distortion.
Crossover Settings (MT-600.4)
- LPF (Low Pass Filter): For channels driving subwoofers or mid-bass speakers, typically 50Hz-500Hz (x1) or 500Hz-5KHz (x10).
- HPF (High Pass Filter): For channels driving full-range or component speakers, typically 50Hz-500Hz (x1) or 500Hz-5KHz (x10).
- Input Mode: Select between 2-channel or 4-channel input mode depending on your head unit's output.
Maintenance
To ensure the longevity and performance of your amplifiers:
- Keep the amplifiers clean and free of dust and debris. Use a soft, dry cloth for cleaning.
- Ensure adequate ventilation around the amplifiers to prevent overheating.
- Periodically check all wiring connections for tightness and corrosion.
- Avoid exposing the amplifiers to extreme temperatures or moisture.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / No Sound | Blown fuse, loose power/ground connection, remote wire disconnected. | Check fuses, verify all power and ground connections, ensure remote wire is connected and receiving 12V. |
| Distorted Sound | Gain set too high, improper crossover settings, speaker impedance mismatch. | Reduce gain, adjust LPF/HPF settings, verify speaker impedance matches amplifier's capabilities. |
| Amplifier Overheating | Insufficient ventilation, impedance too low, prolonged high output. | Ensure proper airflow, check speaker impedance, reduce volume or gain. |
| No Bass (MT20001) | LPF set too high, subsonic filter set too high, bass boost off. | Adjust LPF lower, adjust subsonic filter lower, increase bass boost slightly. |
