Input and Control Panel
Figure 2: Detailed view of the input and control panel, showing RCA inputs and various adjustment knobs.
- RCA Inputs (CH1/2, CH3/4): Nickel-plated jacks for audio signal input from your source unit.
- Level Control: Adjusts the input sensitivity to match the output of your source unit (0.2V - 6V).
- Bass EQ: Provides bass boost control (0dB to +9dB) for enhanced low-frequency response.
- Mode Switch (CH1/2, CH3/4): Selects between 2-channel or 4-channel operation.
- X-OVER Frequency (CH1/2, CH3/4): Variable electronic crossover control (40Hz - 400Hz) for high-pass or low-pass filtering.
- Subsonic Filter (CH3/4): Filters out ultra-low frequencies (ON/OFF) to protect subwoofers.
- Mode Switch (CH3/4): Selects between Stereo or Mono Bridged operation for channels 3 and 4.
Power and Speaker Output Panel

- GND (Ground) Terminal: Connects to the vehicle's chassis ground.
- REM (Remote) Terminal: Connects to the remote turn-on lead from your source unit.
- +12V (Power) Terminal: Connects directly to the vehicle's positive battery terminal via an inline fuse.
- Fuse Holder: Contains a 70A fuse for protection.
- Speaker Output Terminals (CH1+, CH1-, CH2+, CH2-, CH3+, CH3-, CH4+, CH4-): Connects to your speakers. Supports stereo or bridged mono configurations.
- PRT (Protection) Indicator: Illuminates if the amplifier enters protection mode.
- PWR (Power) Indicator: Illuminates when the amplifier is powered on.
Setup and Installation
Proper installation is crucial for optimal performance and safety. Follow these steps carefully.
1. Mounting the Amplifier
The BXX1600.4 is designed for surface mounting. Choose a location that is dry, well-ventilated, and secure, such as under a seat or in the trunk. Ensure there is sufficient airflow around the amplifier to prevent overheating.
- Mark the mounting holes using the amplifier as a template.
- Drill pilot holes if necessary.
- Secure the amplifier using the provided mounting screws.
2. Wiring Connections
Before making any connections, disconnect the vehicle's negative battery terminal.
- Power (+12V) Connection: Run a heavy-gauge power cable (e.g., 4-gauge) from the vehicle's positive battery terminal to the amplifier's +12V terminal. Install an inline fuse holder (70A fuse) within 18 inches of the battery.
- Ground (GND) Connection: Run a heavy-gauge ground cable (same gauge as power) from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid electrical connection.
- Remote (REM) Connection: Connect a remote turn-on wire from your head unit's remote output to the amplifier's REM terminal. This wire turns the amplifier on and off with your head unit.
- RCA Input Connections: Connect RCA cables from your head unit's pre-amp outputs to the amplifier's RCA inputs (CH1/2 and CH3/4). Ensure proper channel matching (left to left, right to right).
- Speaker Output Connections: Connect your speakers to the amplifier's speaker output terminals. Pay close attention to polarity (+ to + and - to -). For 4-channel stereo operation, connect one speaker per channel. For bridged mono operation (e.g., for subwoofers), connect speakers across the bridged terminals as indicated on the amplifier (e.g., CH1+ and CH2- for bridged channel 1/2). The amplifier supports 4-channel stereo or mono bridged operation.
After all connections are made, reconnect the vehicle's negative battery terminal.
Operating the Amplifier
Once installed, you can power on and adjust your amplifier for optimal sound.
- Power On: Turn on your vehicle's ignition and head unit. The PWR indicator on the amplifier should illuminate.
- Set Level Control: Start with the amplifier's Level control at minimum. Play a familiar piece of music through your head unit at about 75% of its maximum volume. Slowly increase the amplifier's Level control until you hear distortion, then back it off slightly.
- Adjust Crossover: Use the X-OVER Frequency controls to set the desired frequency range for your speakers. For full-range speakers, you might use the FULL HP setting. For subwoofers, use the LP (Low Pass) setting and adjust the frequency to blend with your main speakers.
- Adjust Bass EQ: If desired, use the Bass EQ control to boost low frequencies. Use this sparingly to avoid distortion or damage to speakers.
- Select Mode: Ensure the MODE switches are set correctly for your speaker configuration (e.g., 4CH for four speakers, STEREO for two speakers on channels 3/4, or MONO for bridged operation).
Maintenance
Regular maintenance ensures the longevity and performance of your amplifier.
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. 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.
- Connections: Occasionally check all wiring connections to ensure they are secure and free from corrosion.
Troubleshooting
If you experience issues with your amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power (PWR indicator off) | Blown fuse, loose power/ground/remote wire, no remote signal. | Check amplifier fuse (70A). Verify all power, ground, and remote connections are secure. Check head unit's remote output. |
| Amplifier goes into Protection Mode (PRT indicator on) | Overheating, short circuit in speaker wiring, impedance too low. | Ensure proper ventilation. Check speaker wires for shorts. Verify speaker impedance matches amplifier's capabilities (minimum 2 Ohms per channel, 4 Ohms bridged). |
| No Sound Output | Loose RCA cables, incorrect input level, speaker wires disconnected, head unit settings. | Check RCA connections at both amplifier and head unit. Adjust amplifier's Level control. Verify speaker wire connections. Check head unit's volume and source selection. |
| Distorted Sound | Input level too high, improper gain setting, speaker damage, poor ground. | Reduce amplifier's Level control. Check speaker condition. Ensure ground connection is solid. |
