1. Ifihan
The Audison SR 4.300 is a high-performance D-Class 4-channel amplifier designed for car audio systems. This amplifier delivers 85 W x 4 at 4 Ohms and features Audison D-Class Technology (ADT) for compact size without compromising audio quality. Its design incorporates extruded aluminum with rounded corners for easy installation in confined spaces, and generous heat sinks eliminate the need for internal cooling fans. This manual provides essential information for proper installation, operation, and maintenance of your SR 4.300 amplifier.
