The Audiopipe APCLE-18001D is a high-power monoblock Class D amplifier designed to drive subwoofers in a car audio system. To determine the power requirements needed for your Audiopipe APCLE-18001D amplifier, it's essential to consider its power output specifications, efficiency, and how these factors influence the amplifier's current draw from the vehicle's electrical system.
Key Power Specifications of the Audiopipe APCLE-18001D Amplifier:-
Power Output Ratings:
- 1800 watts RMS at 1 ohm
- 1100 watts RMS at 2 ohms
- 600 watts RMS at 4 ohms
-
Class D Amplifier Efficiency:
- Class D amplifiers are known for their high efficiency, typically ranging from 80% to 90%. For this calculation, we'll assume an efficiency of 85% (0.85).
The power requirements for the amplifier are primarily determined by its maximum current draw at full power output. To estimate the current draw (in amps) and the overall power requirements, use the following formula:
Current (Amps)=Power (Watts)Voltage (Volts)×Efficiency\text{Current (Amps)} = \frac{\text{Power (Watts)}}{\text{Voltage (Volts)} \times \text{Efficiency}}Current (Amps)=Voltage (Volts)×EfficiencyPower (Watts)Assuming the amplifier operates at 14.4 volts (which is a typical operating voltage for a car's electrical system when the engine is running and the alternator is charging):
- At 1 Ohm (1800 watts RMS):
- At 2 Ohms (1100 watts RMS):
- At 4 Ohms (600 watts RMS):
To properly power your Audiopipe APCLE-18001D amplifier and ensure reliable operation without straining your vehicle's electrical system, consider the following:
-
High Output Alternator:
- If you plan to run the amplifier at or near its maximum output (especially at 1 ohm), you may need a high-output alternator rated at 200 amps or higher to provide sufficient electrical power to the amplifier and other vehicle systems (lights, air conditioning, etc.).
-
Upgraded Battery:
- A high-performance, deep-cycle battery or a secondary battery dedicated to the audio system can help maintain stable voltage levels during peak current demands, especially when running high-power audio systems.
-
Big 3 Upgrade:
- Perform a Big 3 upgrade, which involves upgrading the vehicle’s main charging system wires:
- Alternator to Battery Wire
- Battery Ground to Chassis Wire
- Engine Ground to Chassis Wire
- This upgrade improves the electrical system’s efficiency and reduces voltage drops under heavy loads.
-
Proper Wiring:
- Use high-quality, adequately sized power and ground wires to connect the amplifier to the vehicle's electrical system. For the Audiopipe APCLE-18001D, a 0-gauge or 2-gauge power wire is recommended to handle the high current draw safely and ensure efficient power delivery.
To power your Audiopipe APCLE-18001D amplifier properly, you need a robust electrical system capable of handling its high current draw, particularly at maximum output levels (up to 147 amps at 1 ohm). Upgrading your alternator, battery, and wiring is essential to provide sufficient power to the amplifier without compromising the vehicle's other electrical systems. By ensuring your electrical system meets these requirements, you can achieve optimal performance and reliable operation from your amplifier.
