Cerwin Vega SRPM700.4DW

The Cerwin-Vega SRPM700.4DW SRPM Stroker 4-Channel Full Range Class-D Amplifier (White). Designed for high-performance car audio and marine-style installations, this amplifier combines advanced Class-D technology, compact design, and powerful output to deliver exceptional sound quality and system flexibility.

Part of the Cerwin-Vega RPM Stroker Series, the SRPM700.4DW is engineered with high-efficiency full-range digital topology, allowing it to deliver strong, clean power while minimizing heat and energy loss. This design ensures that the amplifier produces dynamic, distortion-free sound with impressive headroom, making it ideal for powering speakers in high-performance audio systems.

The amplifier is built with advanced surface mount components and a 4-layer PCB design, providing enhanced reliability, precision, and long-term durability. Despite its powerful performance, the amplifier features a compact chassis with single-sided connections, making it easy to install in tight spaces such as vehicles, motorcycles, boats, and powersports applications.

For maximum system compatibility, the SRPM700.4DW supports both high-level and low-level inputs up to 12V, allowing seamless integration with factory or aftermarket head units. The amplifier also includes multiple speaker-level turn-on options, including VOX signal sensing, DC offset detection, or remote turn-on, giving installers flexibility for different system setups.

Sound customization is simple with fully variable crossovers ranging from 35Hz to 350Hz with 12dB per octave slopes, allowing you to fine-tune frequency response for optimal performance. Convenient top-mounted controls make adjustments quick and easy during installation.

Finished in a sleek white chassis, this amplifier not only performs exceptionally but also adds a clean, modern look to your installation.
