The Audison SR 4.300 is a compact 4-channel Easy D Class car amplifier designed for reliable, efficient power delivery to front and rear speakers or a mixed system with bridged channels. Its small footprint and robust build make it suitable for discreet installations and everyday use.

Integration is straightforward thanks to RCA and speaker-level inputs with auto turn-on for OEM systems. Selectable high-pass, low-pass, and band-pass crossovers support flexible system tuning, while 2 ohm stability and bridgeable channel pairs provide versatile configuration options.
