Cerwin Vega SRPM750.1D SRPM Stroker Class-D Monoblock Amplifier

Cerwin Vega SRPM750.1D 1-Channel SRPM Stroker Class-D Monoblock Amplifier

Cerwin Vega SRPM750.1D is built to give your car audio system powerful subwoofer output, efficient performance, and precise tuning control in a compact monoblock amplifier. As part of the Cerwin-Vega RPM Stroker Series, this Class-D amplifier is designed to drive subwoofers with authority while maintaining clean, distortion-free sound.

Efficient Class-D Power for Powerful Bass

The Cerwin Vega SRPM750.1D uses a high-efficiency Class-D digital amplifier topology that delivers impressive power while minimizing energy loss and heat generation. That efficiency helps the amplifier maintain consistent performance and reliable power delivery, whether you're enjoying everyday music or pushing a high-output car audio system.

Why compromise between strong bass and efficient operation? The SRPM750.1D brings both together in a dedicated monoblock design made for subwoofer applications.

Precision Construction Inside

Performance starts with what's inside the amplifier. The Cerwin Vega SRPM750.1D uses advanced surface-mount components and a durable 4-layer PCB architecture to support excellent signal accuracy and stable operation.

This precision-engineered construction helps the amplifier perform consistently during demanding listening sessions. Think of the 4-layer PCB as the foundation of the amplifier—it provides the structure behind its dependable operation and signal performance.

Compact Chassis and Flexible Inputs

The Cerwin Vega SRPM750.1D features a compact chassis with single-sided connections, giving you a practical design for vehicle audio systems where space matters. The streamlined connection layout helps keep the amplifier's footprint organized without sacrificing useful system compatibility.

Both high-level and low-level inputs up to 12 volts are supported. That makes the amplifier suitable for systems using either factory radios or aftermarket head units.

Fine-Tune Your Subwoofer Performance

The Cerwin Vega SRPM750.1D gives you control over the frequencies reaching your subwoofer with fully variable crossovers ranging from 35Hz to 350Hz. The 12dB per octave filtering provides another layer of control when shaping your system's bass response.

A bass remote control is also included, with optional in-dash mounting. You can adjust bass levels conveniently while driving, giving you an easy way to fine-tune the sound for different music.

Need more bass for one track and a more controlled level for another? The remote puts that adjustment within easy reach.

Flexible Turn-On Options and Phase Control

The Cerwin Vega SRPM750.1D provides several speaker-level turn-on options, including VOX signal sensing, DC offset, and remote turn-on. These options give you flexibility when integrating the amplifier into different vehicle audio systems.

Variable phase adjustment is also included to help align the subwoofer with the rest of your audio system. This gives you another useful tool for getting the subwoofer and other speakers working together as a cohesive system.
