- Power Input (12V): Connect to the positive terminal of the vehicle's battery via a fuse holder (not included) located within 18 inches of the battery. Use 0 Ga wire.
- Ground (GND): Connect to a clean, bare metal point on the vehicle chassis. Use 0 Ga wire, ensuring a secure connection.
- Remote (REM): Connect to the remote turn-on output of your head unit.
- RCA Inputs (CH1, CH2): Connect to the RCA pre-outs of your head unit or signal processor.
- Speaker Outputs (CH1, CH2): Connect your speakers or subwoofers to these terminals. Ensure correct polarity. Use 8 Ga wire.
5. Operating Instructions
5.1. Initial Power-Up and Basic Settings
After completing all wiring, reconnect the vehicle battery. Turn on your head unit. The amplifier's power indicator should illuminate. Begin with all gain controls at minimum and crossover filters set to a neutral position (e.g., full range if available, or a moderate frequency).
5.2. Adjusting Gain and Crossover Filters
The amplifier features independent gain controls for each channel, along with Low Pass Filter (LPF) and High Pass Filter (HPF) adjustments. The LPF and HPF can operate simultaneously for precise sound shaping.

- Gain Control: Adjust the gain to match the output voltage of your head unit. Start low and slowly increase until you hear distortion, then back off slightly. The remote control allows for convenient adjustment of the overall output level.
- Low Pass Filter (LPF): Used for subwoofers or mid-bass speakers. It allows frequencies below the set point to pass through. Adjustable from 50-1200 Hz or 500-12000 Hz.
- High Pass Filter (HPF): Used for full-range or high-frequency speakers. It allows frequencies above the set point to pass through. Adjustable from 10-1200 Hz or 100-12000 Hz.
- Bridge Mode: For increased power output to a single speaker or subwoofer, the amplifier can be bridged. Refer to the specifications for bridge mode power ratings and minimum impedance.
6. Maintenance
The Deaf Bonce Apocalypse AP-ASA-1500.2 amplifier requires minimal maintenance. Periodically inspect all wiring connections to ensure they are secure and free from corrosion. Keep the amplifier's heatsink fins clean and free of dust or debris to maintain proper cooling. Use a soft, dry cloth to clean the exterior of the amplifier. Do not use harsh chemicals or abrasive cleaners.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Amplifier does not power on | No power, ground, or remote signal; Blown fuse | Check all power, ground, and remote connections. Verify fuse integrity and replace if necessary. |
| No sound output | No input signal; Speaker wires disconnected; Amplifier in protection mode | Check RCA input connections. Verify speaker wire connections and polarity. Check for short circuits in speaker wiring. |
| Distorted sound | Gain set too high; Improper crossover settings; Speaker impedance mismatch | Reduce gain level. Adjust LPF/HPF settings. Ensure speaker impedance is within amplifier's supported range. |
| Amplifier overheats | Insufficient ventilation; Low impedance load; Prolonged high output | Ensure proper airflow around the amplifier. Verify speaker impedance. Reduce volume or allow amplifier to cool. |
