Cerwin Vega SRPM1000.1DW SRPM Stroker Monoblock Class-D Amplifier - White

Cerwin Vega SRPM1000.1DW 1-Channel SRPM Stroker Monoblock Class-D Amplifier - White

Cerwin Vega SRPM1000.1DW is a monoblock Class-D amplifier in a white finish, built to deliver powerful subwoofer performance with efficient operation and precise control. As part of the RPM Stroker Series, it combines up to 1000W RMS at 1Ω with flexible inputs, adjustable filtering, bass boost, and remote bass control. If your system needs serious low-frequency output, why settle for an amplifier that gives you less control?

1000W RMS Class-D Power

The Cerwin Vega SRPM1000.1DW delivers 1000W RMS at 1Ω, 800W at 2Ω, and 400W at 4Ω. Its 1-channel monoblock configuration is designed specifically for subwoofer applications, directing its output toward the low end of your car audio system.

The high-efficiency Class-D digital topology allows the amplifier to produce substantial power while minimizing heat and energy consumption. It is designed to provide strong output without making efficiency an afterthought.

RPM Stroker Construction

Inside the RPM Stroker platform, advanced surface-mount components and a durable 4-layer PCB help support signal accuracy and stable performance. This internal design gives the amplifier a solid foundation for operation when your system is working hard.

Compact White Chassis

The Cerwin Vega SRPM1000.1DW measures 10.25 inches long, 5.28 inches wide, and 1.75 inches high. Its compact chassis features single-sided connections, making it easier to work with in spaces where room is limited. The white finish also gives this version a distinctive appearance compared with a traditional black amplifier.

High-Level and Low-Level Inputs

Connecting the amplifier to your audio system is flexible thanks to its high-level and low-level inputs. Low-level input sensitivity ranges from 0.2mV to 10.0V, while the high-level input supports up to 25W RMS. Both input types feature a 22KΩ input impedance, allowing the amplifier to work with factory and aftermarket head units.

Adjustable Low-Pass and Subsonic Filtering

The Cerwin Vega SRPM1000.1DW gives you control over the frequencies sent to your subwoofer. The variable low-pass crossover ranges from 30Hz to 300Hz, while the variable subsonic control ranges from 10Hz to 55Hz. The crossover system provides 1-12dB/Oct filtering.

Why leave your bass response locked to one setting? These adjustable controls let you shape the low end to suit your system, giving you more flexibility when tuning the amplifier.

Variable Phase and Bass Boost

The variable phase adjustment helps align the subwoofer output with the speaker output. The amplifier also provides adjustable bass boost from 0dB to 12dB, giving you another tool for shaping the low-frequency response.

Think of these controls as the fine adjustments on a sound system's dashboard. The amplifier supplies the power, while the tuning features help you decide how that power translates into your bass response.

Remote Bass Control Included

The Cerwin Vega SRPM1000.1DW includes a bass control knob for convenient adjustment of bass levels. The remote control can also be mounted in-dash as an option, allowing you to keep bass adjustment within easy reach from the driver's seat.

Gain and Protection Indicators

An output clipping indicator helps with gain setting, while the LED power/protect light indicator provides a quick visual reference for the amplifier's operating status. The selectable turn-on mode can be configured for REM, VOX, or DC operation.

Performance Specifications

The Cerwin Vega SRPM1000.1DW uses a full WPM power supply with a DC threshold of 10.0V to 17.0V and an idle current of 0.7A. It has an output impedance of 0.047Ω and a damping factor greater than 250 at 50Hz and 4Ω.

The amplifier's bandwidth is 10Hz to 350Hz at -3dB. THD is listed at 0.07% at 1kHz and 4Ω. The signal-to-noise ratio is 77.4 dBA at 1W and 97.4 dBA at full power.

A Purpose-Built Subwoofer Amplifier

The Cerwin Vega SRPM1000.1DW brings together high-output Class-D amplification, flexible input sensitivity, adjustable crossover controls, variable phase, bass boost, and remote bass adjustment. Its compact white chassis keeps the physical footprint modest while the 1000W RMS rating at 1Ω gives your subwoofer system plenty of power to work with.

With its RPM Stroker Series design, durable 4-layer PCB, single-sided connections, and practical tuning controls, the Cerwin Vega SRPM1000.1DW is built for enthusiasts who want more than raw output. It gives you the power to drive your subwoofer and the controls to shape how that power sounds.
