Safety Requirements
To ensure proper use, please read through this manual before using the amplifier. Pay attention to the WARNINGS and CAUTIONS.
- Installation must be done by a qualified professional.
- Wear safety glasses, insulated gloves, and correct tools.
- Use only with 12V batteries.
- Install in a firm place with at least 1" (25mm) space around the heatsink for heat dissipation.
- Avoid dusty, humid, or wet locations. Install away from fuel tanks, fuel lines, heat sources, and other vehicle parts.
- Install a protection fuse or circuit breaker near the battery, with the indicated amperage. Improper fuse use can lead to overheating, smoke, damage, injury, or burns.
- Protect wires from sharp edges using rubber or plastic grommets.
- Disconnect the battery negative terminal before making any connections.
- The amplifier's external surface can become hot during use. Avoid touching the heatsink area and keep children away.
- Avoid continuous exposure to sound pressure levels over 85dB to prevent hearing loss.
- Ensure the amplifier is turned OFF before connecting or disconnecting speaker terminals.
- Dispose of the amplifier responsibly through an electronic product disposal service.
CAUTION: This symbol alerts the user to important instructions. Failure to follow them may result in injury or product damage.
Functions, Inputs & Outputs
The amplifier features several connection points:
- INPUT (R and L): RCA inputs for audio signals from a Head Unit. Use good quality shielded cables to prevent noise.
- LEVEL: Adjusts the amplifier's input sensitivity for optimal matching with various Head Units.
- CROSSOVER:
- HIGH PASS (HPF): Variable adjustment from 10Hz to 90Hz, setting the lower limit of the amplifier's operating frequency.
- LOW PASS (LPF): Variable adjustment from 90Hz to 18KHz, setting the upper limit of the amplifier's operating frequency.
- BASS BOOST:
- FREQ.: Sets the Bass Boost center frequency between 35Hz and 55Hz.
- BOOST: Provides adjustable bass boost from 0 to +10dB at 50Hz.
- MONITOR: Connection for an accessory to monitor amplifier status, including indicator LEDs for distortion (CLIP/TEMP) and protection (PROT).
- SPEAKER: Positive and negative output terminals for connecting speakers. Ensure correct polarity and minimum recommended impedance. For speaker combinations, calculate the resulting impedance.
CAUTION: Output terminals may have voltage when the amplifier is on. Avoid contact to prevent electric shock.
Power Supply Connector
The amplifier has the following power supply connections:
- FAN: Internal ventilation fan for cooling. Ensure at least 1" (25mm) of space around the heatsink for proper airflow. Normal operating temperature is 65°C.
- POSITIVE POWER SUPPLY TERMINAL: Connect a 4 AWG (21mm²) cable directly from the positive battery terminal with a 150A fuse or circuit breaker, placed as close to the battery as possible.
- REMOTE TERMINAL: Connect to the Head Unit's remote output using a 0.75mm² (18 AWG) cable.
- NEGATIVE POWER SUPPLY TERMINAL: Use a short 4 AWG (21mm²) cable connected to the negative battery pole.
It is recommended that all cable ends are tinned for better electrical contact.
CAUTION: Ensure the vehicle battery's negative terminal is disconnected before making any power connections.
LEDs Indicators & Protection Systems
- Blue LED (steady on): Indicates the amplifier is turned on.
- Yellow LED (flashing): Indicates excessive temperature. This can be caused by obstructed fans, improper installation, or poor ventilation. Thermal protection activates around 80°C, interrupting audio and flashing the yellow LED. The fans will operate to cool the unit. Audio is restored when a safe temperature is reached. It is recommended not to turn off the amplifier to speed up cooling.
- Yellow LED (blinking with music): Indicates the amplifier is operating near the distortion threshold. If the red LED also blinks, it indicates excessive distortion.
- Red LED (steady on): Indicates a short circuit or impedance lower than the supported level at the output.
- Red LED (flashes 2x): Indicates supply voltage is below 9V.
- Red LED (flashes 3x): Indicates supply voltage is above 16V.
Installation
CAUTION: All power supply, input, and output connections must be made only with the amplifier turned off.
Recommended Wire Gauge & Fuse
| Component | Gauge | Amperage |
|---|---|---|
| Positive/Negative Power Supply Cable | 4 AWG (21mm²) | 150A |
| Output Cables | 9 AWG (6mm²) | - |
| Remote Cable | 18 AWG (0.75mm²) | - |
| Protection Fuse or Circuit Breaker | - | 150A |
These recommendations are for a maximum cable length of 4m. For longer distances, use thicker gauge cables.
CAUTION: Using wire gauges below the recommendation can result in power loss and overheating of the wiring. Always check polarity and never reverse power supply cables to avoid amplifier damage. It is mandatory to install protection fuses or circuit breakers close to the batteries.
Note: For compression drivers and tweeters, a passive filter must be installed on the positive terminals. Consult the transducer manufacturer's manual.
Examples of power supply connections:
Note: Required battery bank capacity: At least 150Ah.
CAUTION: This equipment is not suitable for use in places where children may be present.
