Setup and Installation

Proper installation is crucial for the performance and longevity of your amplifier. Follow these steps carefully.

1. Pre-Installation Checklist

Read the entire manual before starting.
Gather all necessary tools and wiring materials (power wire, ground wire, remote turn-on wire, RCA cables, speaker wire, fuse holder, fuse).
Disconnect the vehicle's negative battery terminal.
Plan your wiring routes to avoid interference and ensure safety.

2. Mounting Location

Choose a mounting location that is:

Dry and well-ventilated.
Away from direct sunlight or heat sources.
Secure and stable, preventing vibration.
Accessible for wiring and adjustments.

Common locations include under a seat, in the trunk, or behind a panel.

3. Wiring Connections

Refer to Figure 4 for the power and speaker output terminals, and Figure 3 for the input terminals.

Power Wiring (GND, REM, +12V)

GND (Ground): Connect a short (less than 3 feet) heavy-gauge wire from the amplifier's GND terminal to a clean, unpainted metal surface of the vehicle's chassis. Ensure a good electrical connection.
REM (Remote Turn-On): Connect a thin wire from the amplifier's REM terminal to the remote turn-on output of your head unit. This wire turns the amplifier on and off with your stereo.
+12V (Power): Connect a heavy-gauge wire from the amplifier's +12V terminal directly to the positive terminal of the vehicle's battery. Install an appropriate fuse holder with a fuse (not supplied) within 18 inches of the battery.

Recommended Wire Gauge: For optimal performance and safety, use 8-gauge power and ground wire for this amplifier.

Input Signal Connection (RCA or High-Level)

RCA Input: If your head unit has RCA pre-outs, connect RCA cables from the head unit's subwoofer or full-range output to the amplifier's "INPUT" RCA jacks.
High-Level Input: If your head unit does not have RCA outputs, use the high-level input feature. Connect the speaker wires from your head unit's speaker outputs directly to the amplifier's high-level input connector (if provided, typically a multi-pin connector).

Speaker Output Connection

Connect your subwoofer(s) to the "SPEAKER OUTPUT" terminals. Ensure correct polarity (+ to + and - to -).
The XED3001D is a monoblock amplifier, designed for a single subwoofer or multiple subwoofers wired to a compatible impedance. Refer to your subwoofer's specifications for proper wiring configurations and impedance matching. The amplifier supports a minimum impedance of 2 Ohms.

Remote Bass Level Control (Optional)

If your amplifier came with a remote bass level control, connect its cable to the "REMOTE" port on the amplifier's input side (Figure 3). Route the cable to a convenient location for the driver.

Operating the Amplifier

Once installed, you can adjust the amplifier's settings to optimize sound performance.

Initial Power-Up

After all connections are made and checked, reconnect the vehicle's negative battery terminal.
Turn on your head unit. The amplifier should power on automatically (indicated by a power LED, if present).
Start with all amplifier settings at their minimum or flat positions.

Audio Adjustments (Refer to Figure 3)

GAIN Control: This matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain at minimum. Play a familiar song at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear slight distortion, then back off slightly. This is the maximum clean output.
LPF (Low Pass Filter): This filter allows only frequencies below the set point to pass through to the subwoofer. For subwoofers, a common range is 80Hz-120Hz. Adjust this to blend smoothly with your main speakers.
SUBSONIC Filter: This high-pass filter removes extremely low frequencies that are below the audible range or below the tuning frequency of a ported enclosure. This protects the subwoofer from over-excursion and improves sound quality. A common setting is 25Hz-30Hz.
BASS BOOST: This control provides an increase in output at a specific low frequency. Use sparingly, as excessive bass boost can lead to distortion and potential damage to your subwoofer.

Maintenance

Your Cerwin-Vega amplifier requires minimal maintenance. Follow these guidelines to ensure its longevity:

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 heat sink fins are free from dust and debris to allow for proper heat dissipation. Do not block any ventilation openings.
Connections: Occasionally check all wiring connections to ensure they are secure and free from corrosion.

Troubleshooting

If you experience problems with your amplifier, consult the following troubleshooting guide before contacting support.

Problem	Possible Cause	Solution
No Power / Amplifier Not Turning On	Blown fuse (in-line or amplifier). Poor ground connection. No remote turn-on signal. Loose power wire.	Check and replace fuses. Ensure ground wire is securely connected to clean metal. Verify remote wire connection to head unit and amplifier. Check +12V power connection at battery and amplifier.
No Sound Output	Gain set too low. RCA cables disconnected or faulty. Speaker wires disconnected or shorted. Head unit volume too low or muted.	Increase gain slowly. Check RCA connections and try new cables. Inspect speaker wiring for shorts or breaks. Increase head unit volume.
Distorted Sound	Gain set too high. Speaker impedance too low. Poor ground connection. Damaged speaker.	Reduce gain setting. Verify speaker impedance is compatible (minimum 2 Ohms). Improve ground connection. Test speaker with another amplifier or source.
Amplifier Overheating / Goes into Protect Mode	Insufficient ventilation. Speaker impedance too low. Short circuit in speaker wiring. Gain set too high, causing clipping.	Ensure adequate airflow around the amplifier. Check speaker impedance. Inspect speaker wires for shorts. Reduce gain setting.
