• SPEED-FET MOSFET Components: Exclusive Crunch SPEED-FET MOSFET components maximize power efficiency, improve sound quality, and minimize distortion.
• Variable Electronic Crossovers: Provides complete control over the sound output.
• Bass Remote Included: A wired bass remote allows convenient adjustments to bass frequencies from anywhere in the vehicle.
• 1 Ohm Stable: Capable of operating with a 1-ohm load for maximum power output.

4. Setup and Installation

Proper installation is crucial for the performance and safety of your amplifier. Follow these general guidelines:

4.1 Mounting Location

• Choose a dry, well-ventilated area, away from direct sunlight or heat sources.
• Ensure the mounting surface is sturdy and can support the amplifier's weight.
• Allow sufficient space around the amplifier for air circulation.

4.2 Wiring Connections

Refer to Figure 2 for the power, ground, remote, and speaker connections. Use appropriate gauge wiring for all connections to prevent power loss and ensure safety.

Figure 2: Power, Ground, Remote, and Speaker Terminals.

1. Power (POWER +12V): Connect a fused power cable directly from the positive terminal of your vehicle's battery to the +12V terminal on the amplifier. The fuse should be located within 18 inches of the battery.
2. Ground (GND): Connect a ground cable of the same gauge as the power cable to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
3. Remote (REM): Connect a remote turn-on wire from your head unit's remote output to the REM terminal on the amplifier. This wire signals the amplifier to turn on and off with your head unit.
4. Speaker (SPEAKER): Connect your subwoofer(s) to the speaker terminals. Ensure correct polarity (+ to + and - to -) and verify the total impedance matches the amplifier's capabilities (1 Ohm stable).
5. RCA Input (LINE-INPUT): Connect RCA cables from your head unit's subwoofer output to the LINE-INPUT on the amplifier.
6. Hi-Input: If your head unit does not have RCA outputs, use the Hi-Input connection. Consult a professional for proper wiring.

5. Operation and Adjustments

The amplifier features several controls to fine-tune your audio output. Refer to Figure 3 for the location of these controls.

Figure 3: Amplifier Control Panel (Low Pass, Subsonic, Bass Boost, Level, Line-Input, Hi-Input).

• LOW PASS (40Hz - 300Hz): This control sets the upper frequency limit for the subwoofer. Frequencies above this setting will be filtered out. Start at a lower setting (e.g., 80Hz) and adjust to blend with your main speakers.
• SUBSONIC (10Hz - 40Hz): This filter removes extremely low frequencies that are inaudible and can cause damage to subwoofers. Set it slightly below your subwoofer's lowest resonant frequency.
• BASS BOOST (0dB - 12dB): Adjusts the bass level at a specific frequency (typically around 45Hz). Use sparingly to avoid distortion.
• LEVEL (0.2V - 6V): This is the gain control, matching the amplifier's input sensitivity to the output voltage of your head unit. Set it to the lowest possible setting that achieves maximum clean output from your head unit.
• LINE-INPUT (RCA): Connect your head unit's RCA outputs here.
• HI-INPUT: For head units without RCA outputs.

5.1 Bass Remote

The included wired bass remote allows for convenient adjustment of the bass output level from the driver's seat. Connect the remote to the dedicated port on the amplifier (CR-U-01, see Figure 3).

6. Maintenance

To ensure the longevity and optimal performance of your Crunch amplifier, follow these simple maintenance tips:

• Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Connections: Regularly check all power, ground, remote, and speaker connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
• Ventilation: Ensure that the amplifier's heatsink fins are free from dust and debris to maintain proper cooling. Do not block any ventilation openings.
• Environment: Avoid exposing the amplifier to extreme temperatures, humidity, or direct sunlight.
