The SAEv4 is engineered with high-fidelity Class A/B multi-channel architecture, providing an ideal balance between performance and affordability. Leveraging the latest half-bridge technology, these amplifiers deliver clean, powerful audio signals in a compact form factor.
Featuring an all-new chassis and heatsink design with 33% more aluminum, this SAEv4 keeps your system cool even during intense listening sessions. The amp is packed with a variable subsonic, high pass and low pass filters, plus a 4-way protection circuit (thermal, voltage, speaker short, and DC offset).
With an input sensitivity of 6V max and RMS power output of 125W x 4 at 2 ohms and 100W x 4 at 4 ohms, the SAEv4-100.4 is designed to drive your car audio system with precision and clarity. The variable crossover slope (LPF/HPF) and a high signal-to-noise ratio of 92dB further enhance audio quality, with an exceptionally low noise floor.
