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

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

Cerwin Vega SRPM1000.1D is a monoblock Class-D amplifier built to deliver serious subwoofer power with precise control and efficient operation. With up to 1000W RMS at 1Ω, a compact chassis, flexible input options, and a wide range of tuning controls, it gives you a strong foundation for a high-output car audio system. Looking for deep, controlled bass without a bulky amplifier taking over your setup? This model keeps the focus where it belongs: on the subwoofer.

1000W RMS of Subwoofer Power

The Cerwin Vega SRPM1000.1D delivers 1000W RMS at 1Ω, 800W at 2Ω, and 400W at 4Ω. That gives you different power levels depending on the impedance of your system. As a monoblock amplifier, it is purpose-built for driving a subwoofer, putting its output toward the low frequencies where you want it most.

Efficient Class-D Amplification

The high-efficiency Class-D digital design helps produce substantial output while minimizing heat and energy consumption. It's a bit like getting more work done without making the system work harder than necessary. For a high-performance subwoofer setup, that efficiency can be an important part of the overall amplifier design.

Built With a Durable 4-Layer PCB

Inside the RPM Stroker platform, advanced surface-mount components and a durable 4-layer PCB support signal accuracy and stable performance. The internal construction is designed to keep the amplifier operating smoothly when your audio system demands more from it.

Compact Chassis for Flexible Placement

The Cerwin Vega SRPM1000.1D Amplifier measures 10.25 inches long, 5.28 inches wide, and 1.75 inches high. Its compact chassis uses single-sided connections, helping keep the layout practical when space is limited. With its relatively slim 1.75-inch height, the amplifier can fit into setups where a larger chassis would be difficult to accommodate.

Flexible Input Options

Need to connect it to a factory or aftermarket audio system? The amplifier supports both low-level and high-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 have a 22KΩ impedance.

Adjustable Crossover and Subsonic Control

The Cerwin Vega SRPM1000.1D gives you plenty of control over the frequencies reaching your subwoofer. Its variable low-pass crossover ranges from 30Hz to 300Hz, while the variable subsonic filter ranges from 10Hz to 55Hz. Both are part of the amplifier's 1-12dB/Oct crossover system.

Why settle for a fixed setting when you can fine-tune the low end? These controls let you shape the amplifier's frequency response around your system rather than treating every setup the same.

Bass Boost and Remote Bass Control

For additional low-frequency adjustment, the amplifier provides bass boost from 0dB to 12dB. A bass control knob is included as well, giving you a convenient way to adjust bass levels. The amplifier also supports an optional in-dash mounting arrangement for the bass remote control.

Variable Phase Adjustment

The variable phase adjustment helps align subwoofer and speaker output. This gives you another useful tuning tool when dialing in the overall bass response of your system. Think of it as adjusting the timing of two pieces of a puzzle so they work together instead of fighting each other.

Gain Setting and Protection Features

The Cerwin Vega SRPM1000.1D includes an output clipping indicator to help with gain adjustment. An LED power/protect light indicator provides additional information about the amplifier's operating status. The selectable turn-on mode can be set to REM, VOX, or DC, giving you several options for how the amplifier activates.

Power Supply and Performance Specifications

The amplifier uses a full WPM power supply and has a DC power supply threshold of 10.0V to 17.0V. Its idle current is listed at 0.7A. The output impedance is 0.047Ω, with a damping factor greater than 250 at 50Hz and 4Ω.

For signal performance, the amplifier has a bandwidth of 10Hz to 350Hz. THD is listed at 0.07% at 1kHz and 4Ω, while the signal-to-noise ratio is 77.4 dBA at 1W and 97.4 dBA at full power.

What Makes the RPM Stroker a Practical Choice?

The Cerwin Vega SRPM1000.1D brings together high-output Class-D amplification, flexible connectivity, adjustable crossover controls, bass boost, phase adjustment, and remote bass control in a compact chassis. It is designed specifically around subwoofer performance, giving you both the power and the tuning options needed to shape the low end of your car audio system.

With 1000W RMS available at 1Ω and additional output ratings at 2Ω and 4Ω, the Cerwin Vega SRPM1000.1D offers a flexible approach to powering a subwoofer. Add its compact dimensions, high-level and low-level inputs, adjustable filtering, clipping indicator, and included bass control knob, and you have an amplifier designed to put substantial power and hands-on control in the same package.
