Skar Audio RP-800.1D 800W RMS Class D Monoblock Subwoofer Amplifier with Remote Bass Control

Skar Audio RP-800.1D Power Specifications

Pro Street Tip: The 800W RMS rating is the important figure when matching this amplifier to a subwoofer. The 1,200W peak rating does not represent continuous power output.

High-Efficiency Class D MOSFET Amplification

The RP-800.1D uses Class D amplifier technology to deliver strong low-frequency output while reducing wasted electrical energy compared with less efficient amplifier designs.

Its high-speed MOSFET power supply supports the internal power conversion needed for demanding subwoofer operation.

The amplifier also features an advanced PCB layout designed to support reliable electrical performance.

This combination makes the RP-800.1D well suited for daily-driven vehicles where efficient power delivery and manageable installation requirements matter.

Although Class D amplifiers are generally more efficient than traditional Class A/B designs, a high-output bass system still requires adequate electrical capacity.

Proper battery condition, alternator output, wiring, and grounding remain essential.

1-Ohm Stable for Flexible Subwoofer Configurations

The Skar Audio RP-800.1D supports speaker loads as low as 1 ohm.

This gives enthusiasts flexibility when selecting compatible single- or multiple-subwoofer configurations.

Single-Subwoofer Installations

A compatible dual-voice-coil subwoofer may be wired to present a suitable final impedance.

Dual-Subwoofer Installations

Two compatible subwoofers may be wired together to create a supported final load.

The correct configuration depends on the impedance of each voice coil and the manufacturer’s recommended wiring arrangements.

Important: Never connect a final speaker load below 1 ohm. Doing so can cause excessive current demand, amplifier protection events, or permanent equipment damage.

Adjustable Bass EQ for Customized Output

The RP-800.1D includes a three-position bass EQ switch that provides additional emphasis at 45 Hz.

0 dB — Flat Bass Response

Disables additional bass boost.

This is the recommended starting point when setting amplifier gain and crossover controls.

+6 dB — Moderate Bass Boost

Adds noticeable emphasis around 45 Hz for compatible systems that can accommodate the increased output demand.

+12 dB — Maximum Bass Boost

Provides aggressive emphasis around 45 Hz.

This setting can significantly increase the risk of clipping, excessive subwoofer excursion, and thermal stress.

Pro Street Tip: Start with bass EQ at 0 dB. Proper enclosure design and gain calibration are more important than maximizing bass boost.

Variable Low-Pass Filter

The Skar Audio RP-800.1D features an adjustable low-pass filter that controls the upper-frequency range delivered to the connected subwoofer.

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

For many aftermarket car audio systems, approximately 80 Hz is a useful initial crossover setting.

Final adjustment depends on the connected speakers, subwoofer enclosure, and vehicle acoustics.

Adjustable Subsonic Filter

The RP-800.1D includes a variable subsonic filter designed to reduce extremely low-frequency content.

This is especially useful in ported subwoofer enclosures, where frequencies below the enclosure’s tuning point can cause excessive cone movement.

Correct subsonic filtering can help reduce unnecessary mechanical stress on the connected subwoofer.

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

Avoid selecting a filter frequency without considering the enclosure’s tuning characteristics.

Adjustable Gain Control

The amplifier includes a variable gain control for matching its input sensitivity to the connected head unit or signal processor.

Gain is not a volume control.

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

Improper gain adjustment can introduce clipping and potentially damage the connected subwoofer.

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

Included Remote Subwoofer Level Controller

The Skar Audio RP-800.1D includes a remote bass level controller that allows convenient adjustment from the driver’s seat.

This is particularly useful when switching between music genres with different bass content.

The controller lets you reduce or adjust subwoofer output within the amplifier’s properly calibrated operating range.

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

Once the amplifier is correctly tuned, the remote controller provides convenient everyday bass management without requiring access to the amplifier itself.

Oversized 4-Gauge Power and Ground Terminals

The RP-800.1D features 4-gauge power and ground input terminals designed for high-current electrical connections.

These terminals accommodate appropriately sized amplifier wiring and help support reliable power delivery when installed correctly.

For a high-output subwoofer amplifier, electrical installation quality is especially important.

Use manufacturer-recommended cable sizes, suitable circuit protection, and a secure ground connection.

Pro Street Installation Tip: The 4-gauge terminal size identifies the amplifier’s connection capacity. Always select cable and fuse sizes according to the manufacturer’s instructions, cable length, and electrical load.

Four-Way Amplifier Protection Circuitry

The Skar Audio RP-800.1D includes four-way protection circuitry designed to respond to abnormal operating 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 eliminate the risk of damage from improper wiring, incorrect speaker impedance, or excessive gain settings.

Efficient Heatsink Design

The RP-800.1D uses an efficient heatsink design to help dissipate heat during operation.

Thermal management is important when powering high-output subwoofers, particularly during extended bass-heavy listening sessions.

Install the amplifier in a secure, ventilated location.

Avoid mounting it where airflow is restricted or where the housing may be exposed to moisture, excessive heat, or physical damage.

Ideal for 10-Inch and 12-Inch Subwoofer Systems

The Skar Audio RP-800.1D is a practical choice for many aftermarket subwoofer configurations.

Potential applications include:

• Single high-output 10-inch subwoofer systems
• Single 12-inch performance subwoofer installations
• Compatible dual 10-inch subwoofer configurations
• Moderate-power dual 12-inch systems
• Custom sealed subwoofer enclosures
• Properly designed ported subwoofer boxes
• Daily-driver bass upgrades

Subwoofer diameter alone does not determine compatibility.

Always match the amplifier to the connected subwoofer system’s final impedance, combined RMS power handling, and enclosure requirements.

Factory Stereo and Aftermarket Head Unit Integration

The RP-800.1D can be integrated into many factory and aftermarket audio systems using appropriate signal connections and installation hardware.

Aftermarket Head Unit Installation

For compatible aftermarket stereos, connect the head unit’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 original factory radio, additional integration hardware may be required.

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

Do not assume the amplifier accepts direct high-level speaker inputs unless the manufacturer’s specifications explicitly confirm that capability.
