5. Setup and Installation
Proper installation is crucial for optimal performance and safety. If you are not comfortable performing the installation yourself, seek professional assistance.
5.1 Mounting the Amplifier
Choose a mounting location that is dry, well-ventilated, and secure. Avoid mounting the amplifier directly on carpet or in enclosed spaces without airflow. Ensure there is enough space around the amplifier for air circulation.
- Place the amplifier in the desired location and mark the mounting holes.
- Drill pilot holes if necessary, ensuring no wires or fuel lines are behind the drilling surface.
- Secure the amplifier using the provided mounting screws.
5.2 Wiring Connections
All wiring should be done with the vehicle's battery disconnected. Use high-quality wiring to minimize signal loss and ensure safety.

This image displays the top view of the Quantum QE2000.4 amplifier, showing the Quantum Audio logo, "Xtreme 4 Channel Stereo Amplifier" branding, "QE2000.4 2000W" model and power rating, RCA input jacks on the left, and power/speaker terminals on the right. The heat sink fins are visible across the top surface.
5.2.1 Power and Ground Connections
- Power (BATT+): Connect a heavy-gauge wire (e.g., 4 AWG or 8 AWG depending on power requirements) directly from the positive terminal of the vehicle's battery to the BATT+ terminal on the amplifier. Install an in-line fuse holder within 18 inches (45 cm) of the battery.
- Ground (GND): Connect a heavy-gauge wire of the same size as the power wire from the GND terminal on the amplifier to a clean, unpainted metal surface of the vehicle's chassis. Ensure a good electrical connection.
- Remote (REM): Connect a smaller gauge wire (e.g., 18 AWG) from the REM terminal on the amplifier to the remote turn-on output of your head unit. This wire turns the amplifier on and off with your stereo.
5.2.2 RCA Input Connections
Connect RCA cables from the pre-amp outputs of your head unit to the RCA input jacks on the amplifier. Ensure correct channel matching (Front Left, Front Right, Rear Left, Rear Right).
5.2.3 Speaker Output Connections
Connect your speakers to the speaker output terminals on the amplifier. Observe correct polarity (+ to + and - to -) for each speaker. The QE2000.4 supports various speaker configurations (stereo, bridged mono). Refer to the amplifier's terminal markings for specific connections.
- Stereo Mode: Connect one speaker to each channel's positive and negative terminals.
- Bridged Mode: For higher power output to a single speaker (e.g., a subwoofer), connect the speaker across the designated bridged terminals (typically the positive of one channel and the negative of the adjacent channel). Consult the amplifier's specific bridging instructions.
5.3 Initial Settings
- Gain Control: Start with the gain control set to minimum. Gradually increase it until the desired volume is achieved without distortion. Do not use the gain control as a volume knob.
- Crossover (LPF/HPF): Adjust the Low-Pass Filter (LPF) or High-Pass Filter (HPF) according to your speaker type and desired frequency response.
- HPF (High-Pass Filter): Allows frequencies above the set point to pass. Typically used for full-range speakers to remove bass frequencies they cannot reproduce.
- LPF (Low-Pass Filter): Allows frequencies below the set point to pass. Typically used for subwoofers to only reproduce bass frequencies.
6. Operating the Amplifier
Once properly installed and configured, the amplifier will turn on automatically when your head unit is powered on (via the remote wire). Adjust volume and tone settings primarily from your head unit.
- Power Indicator: A power LED (usually green) will illuminate when the amplifier is receiving power and is operational.
- Protection Indicator: A protection LED (usually red) will illuminate if the amplifier detects a fault (e.g., overheating, short circuit, low voltage). If this light comes on, turn off your system immediately and troubleshoot the issue.
- Volume Control: Use your head unit's volume control for daily operation. The amplifier's gain control should only be set once during initial setup.
7. Maintenance
The Quantum QE2000.4 amplifier requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth to remove dust. Do not use harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the amplifier's cooling fins are free from obstructions to allow for proper heat dissipation.
- Connections: Occasionally check all wiring connections for tightness and corrosion. Loose connections can lead to poor performance or damage.
