Skar Audio RP-2000.1D Monoblock Class D MOSFET Amplifier with Remote Subwoofer Level Control, 2000W

Skar Audio RP-2000.1D Power Specifications

Pro Street Tip: The 2,000W RMS rating is the important figure when matching this amplifier to a subwoofer. The 2,800W peak rating does not represent continuous output.

Built for High-Power Subwoofer Systems

The RP-2000.1D is an excellent option for enthusiasts building substantial aftermarket bass systems.

Its 2,000W RMS output at 1 ohm provides flexibility when selecting compatible subwoofers.

Single 2,000W RMS Subwoofer

A properly matched high-output subwoofer rated around 2,000 watts RMS may be a suitable choice when its impedance and enclosure requirements are compatible.

Dual 1,000W RMS Subwoofers

The amplifier may also power two compatible subwoofers rated around 1,000 watts RMS each.

When wired correctly, this configuration can distribute amplifier output across both drivers.

Actual power distribution depends on the speakers’ impedance, wiring arrangement, and operating conditions.

Custom High-Output Bass Systems

The RP-2000.1D can also serve as the foundation for a custom trunk installation or competition-oriented audio build.

However, amplifier power alone does not determine acoustic output.

Subwoofer efficiency, enclosure design, vehicle acoustics, electrical supply, and system tuning all influence performance.

Efficient Class D MOSFET Amplification

The RP-2000.1D uses Class D amplifier technology to deliver substantial low-frequency output while reducing wasted electrical energy.

Class D amplifiers are generally more efficient than comparable Class A/B designs, making them especially useful for high-power subwoofer applications.

The amplifier also features a high-speed MOSFET power supply designed to support its internal electrical requirements.

Combined with an advanced PCB layout, this architecture helps deliver substantial power in a dedicated monoblock configuration.

Even with efficient Class D operation, a 2,000W RMS amplifier places significant demands on the vehicle’s electrical system.

Proper battery condition, alternator capacity, wiring, and grounding are essential.

1-Ohm Stable for High-Output Bass Configurations

The Skar Audio RP-2000.1D supports speaker loads as low as 1 ohm.

This allows compatible subwoofers to be wired into low-impedance configurations that take advantage of the amplifier’s rated output.

Why Final Impedance Matters

Subwoofer impedance directly affects the electrical load presented to the amplifier.

Incorrect voice-coil wiring can produce a final impedance that is too low for safe operation.

A load below the amplifier’s rated minimum may cause excessive current demand, protection events, overheating, or equipment damage.

Important: Never wire the RP-2000.1D below its 1-ohm minimum rated impedance.

Before installation, calculate the final impedance of every connected voice coil and subwoofer.

Oversized 1/0 AWG Power and Ground Terminals

One of the RP-2000.1D’s important design features is its oversized 1/0 AWG power and ground terminals.

High-output amplifiers require substantial electrical current, particularly when operating near their rated output.

The larger terminals accommodate appropriately sized power and ground connections.

Benefits of Proper High-Current Wiring

• Helps reduce voltage drop.
• Supports reliable amplifier operation.
• Reduces unnecessary resistance in electrical connections.
• Supports high-current power delivery.
• Helps minimize electrical heating caused by undersized wiring.

Pro Street Installation Tip: Terminal size does not determine the required fuse rating. Follow Skar Audio’s installation instructions when selecting cable size and circuit protection.

At this power level, evaluate the vehicle’s charging system before installation.

Depending on the existing electrical system and listening demands, upgraded electrical components may be necessary.

Selectable Bass EQ at 45 Hz

The RP-2000.1D features an onboard bass EQ switch with three settings.

This allows you to customize low-frequency emphasis based on your listening preferences and subwoofer system.

However, bass boost increases the output demand placed on the amplifier and connected subwoofers.

At high power levels, excessive bass boost can quickly contribute to clipping, excessive cone movement, and thermal damage.

Pro Street Tip: Start with bass EQ at 0 dB. Correct enclosure design, gain calibration, and crossover settings are more important than maximum bass boost.

Variable Low-Pass Filter

The Skar Audio RP-2000.1D includes a variable low-pass filter designed to control the upper-frequency content delivered to connected subwoofers.

This helps prevent unwanted midrange frequencies from reaching speakers intended primarily for bass reproduction.

For many aftermarket car audio systems, approximately 80 Hz is a useful initial crossover setting, provided the amplifier’s adjustment range supports it.

Final settings depend on the subwoofer system, enclosure, and vehicle acoustics.

Variable Subsonic Filter

The RP-2000.1D includes a variable subsonic filter that reduces extremely low-frequency content.

This is particularly useful in ported subwoofer enclosures.

At frequencies below a ported enclosure’s tuning point, cone movement can increase significantly while useful acoustic output decreases.

Proper subsonic filtering helps reduce unnecessary mechanical stress on the connected subwoofers.

Set the filter according to the subwoofer and enclosure manufacturer’s recommendations.

Adjustable Gain Control

The amplifier features variable gain adjustment for matching input sensitivity to the connected head unit or signal processor.

Gain is not a volume control.

Turning the gain to maximum does not increase the amplifier’s clean rated power.

Incorrect gain settings can introduce clipping and potentially damage connected subwoofers.

For best results, calibrate gain using an appropriate measurement method and the manufacturer’s installation instructions.

Remote Subwoofer Level Controller Included

The Skar Audio RP-2000.1D includes a remote bass level controller that allows convenient adjustment from the driver’s seat.

This is particularly useful when switching between music genres or adjusting bass output for passengers.

The remote controller provides convenient level adjustment within the amplifier’s calibrated operating range.

It does not increase the amplifier’s maximum clean power output.

Four-Way Protection Circuitry

The RP-2000.1D includes four-way protection circuitry designed to respond to abnormal electrical and thermal conditions.

Manufacturer-described protection features include safeguards associated with:

• Electrical short circuits
• Excessive amplifier temperatures
• Low supply voltage
• Additional abnormal electrical operating conditions

These features help protect the amplifier, but they do not replace proper installation, correct speaker impedance, or adequate ventilation.

Efficient Heatsink Design

The RP-2000.1D incorporates an efficient heatsink design to help manage operating temperatures.

Thermal management is particularly important in high-output amplifiers because substantial electrical power produces heat even in efficient Class D designs.

For best results, mount the amplifier in a secure location with adequate airflow.

Avoid covering the amplifier or placing it near excessive heat sources.

Vehicle Electrical System Requirements

A 2,000W RMS subwoofer amplifier requires careful electrical planning.

At high output, the RP-2000.1D can place significant demands on the vehicle’s alternator, battery, and wiring.

Electrical Considerations

Alternator Capacity: Verify that the charging system can support the amplifier and the vehicle’s existing electrical loads.

Battery Condition: Use a healthy battery capable of supporting the system’s electrical requirements.

Power Wiring: Use properly sized cable according to the amplifier manufacturer’s specifications.

Grounding: Ensure the ground connection is secure and has low electrical resistance.

Circuit Protection: Install appropriate protection close to the battery.

Voltage Monitoring: Monitor supply voltage during initial testing and high-output operation.

Pro Street Tip: A high-output amplifier cannot compensate for an inadequate electrical system. Voltage drop can reduce performance and increase the likelihood of protection events.

Factory Stereo and Aftermarket Head Unit Integration

The RP-2000.1D can be integrated into many aftermarket and factory audio systems using appropriate signal connections and installation hardware.

Aftermarket Stereo Installation

For compatible aftermarket head units, connect the stereo’s subwoofer preamp output to the amplifier using suitable RCA cables.

Then connect the amplifier to the properly configured subwoofer system.

Factory Stereo Installation

If you’re retaining your factory radio, additional integration equipment may be required.

Depending on the vehicle, this may include a line output converter, digital signal processor, or factory amplifier integration interface.

The supplied specifications do not confirm integrated high-level speaker inputs, so do not assume factory speaker wires can connect directly to the amplifier.
