Safety Information

• Always disconnect the vehicle's battery negative terminal before starting any installation.
• Ensure all wiring is properly routed and secured to prevent damage or short circuits.
• Use appropriate wire gauges for power and ground connections as specified in the installation section.
• Install the amplifier in a location that allows for adequate ventilation to prevent overheating.
• If you are unsure about any part of the installation process, consult a professional car audio installer.

Product Overview and Controls

The EVO4000.1 is a Class D monoblock amplifier designed for high-power subwoofer applications. It features a range of controls to fine-tune your audio experience.

Control Panel Features:

• Input (RCA): Low-level RCA inputs for connecting to your head unit's pre-amp outputs.
• Gain Control: Adjusts the input sensitivity of the amplifier to match the output of your head unit.
• Bass Boost: Provides adjustable bass enhancement for deeper low-frequency response.
• Phase Shift (0-180°): Allows adjustment of the subwoofer's phase to optimize integration with other speakers.
• LPF (Low Pass Filter): A variable filter that allows only frequencies below the set point to pass through to the subwoofer.
• Remote: Port for connecting an optional remote subwoofer level control.
• Protect Indicator: Illuminates if the amplifier enters protection mode due to overheating, short circuit, or low voltage.
• Power Indicator: Illuminates when the amplifier is powered on and operating normally.

Some models in the Sound Storm Laboratories BX series, such as the BXA15001, BXA5002, and BXA6404, also feature high-level inputs for direct connection to speaker outputs from a factory head unit. The BXA5002 and BXA6404 models include switches for Low Pass Filter (LPF), High Pass Filter (HPF), and Full-Range operation, offering versatile crossover options.

Setup and Installation

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

1. Disconnect Battery:

Before starting any wiring, always disconnect the negative (-) terminal of your vehicle's battery to prevent electrical shorts.

2. Power Wire Installation:

Run a heavy-gauge power cable (e.g., 4-gauge or larger, depending on total system wattage) from the positive (+) terminal of your car battery to the amplifier location. Ensure the cable is protected by an in-line fuse holder within 18 inches of the battery. The fuse rating should match the amplifier's requirements. Route the power cable away from other vehicle wiring to prevent noise interference.

3. Ground Wire Installation:

Connect a heavy-gauge ground cable (same gauge as the power wire) from the amplifier's ground terminal to a clean, solid metal point on the vehicle's chassis. Ensure the connection point is free of paint, rust, or dirt for optimal conductivity. The ground wire should be as short as possible, ideally less than 3 feet.

4. Remote Turn-On Wire:

Run a remote turn-on wire (typically 18-gauge) from your head unit's remote output to the amplifier's REM terminal. This wire tells the amplifier to turn on when your head unit is active.

5. RCA Signal Cables:

Connect RCA cables from your head unit's pre-amp outputs to the amplifier's RCA inputs. Route these cables away from power wires to minimize noise.

6. Speaker/Subwoofer Wiring:

Connect your subwoofer(s) to the amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -) and that the total impedance of your subwoofer(s) matches the amplifier's stable impedance rating (e.g., 1 Ohm for the EVO4000.1).

Operating Instructions

Once installed, follow these steps to configure and operate your amplifier:

1. Initial Setup:

• Turn your head unit volume to about 75% of its maximum.
• Set the amplifier's Gain control to minimum.
• Play a music track with strong bass content.

2. Adjust Gain:

Slowly increase the amplifier's Gain control until you hear slight distortion, then back it off slightly until the sound is clear. This matches the amplifier's input to your head unit's output.

3. Set Low Pass Filter (LPF):

Adjust the LPF control to filter out higher frequencies from your subwoofer. A common starting point is between 80Hz and 120Hz, but this can be adjusted based on your subwoofer and personal preference.

4. Adjust Bass Boost:

If desired, slowly increase the Bass Boost control to enhance low frequencies. Use sparingly to avoid distortion and potential damage to your subwoofer.

5. Phase Shift:

Experiment with the Phase Shift control (0° or 180°) to find the setting that provides the most impactful and cohesive bass response with your other speakers.

6. Remote Subwoofer Control:

If using an optional remote level control, connect it to the 'Remote' port. This allows convenient adjustment of the subwoofer's output from the driver's seat.

Maintenance

• Keep the amplifier clean and free of dust and debris. Use a soft, dry cloth for cleaning.
• Ensure adequate airflow around the amplifier to prevent overheating. Do not block ventilation fins.
• Periodically check all wiring connections for tightness and corrosion.

Troubleshooting

If you experience issues with your amplifier, refer to the following common troubleshooting steps:

• No Power: Check the in-line fuse near the battery and the fuses on the amplifier. Verify power, ground, and remote turn-on connections.
• No Sound: Check RCA signal cables for proper connection and damage. Verify speaker wiring and ensure the head unit is sending an audio signal.
• Distorted Sound: Reduce the amplifier's gain control. Check speaker wiring for shorts. Ensure the subwoofer's impedance is compatible with the amplifier.
• Amplifier Overheating (Protect Light On): Ensure adequate ventilation. Check speaker impedance. Reduce gain or bass boost settings.
