Upgrade your car audio system with the Reference Series 4-Channel Class H Car Amplifier , a versatile and efficient amplifier designed to deliver clean, controlled power to your vehicle's speakers. With a total power output of 400 watts , the amplifier delivers 75W × 4 channels at 4Ω , 100W × 4 channels at 2Ω , or up to 200W × 2 channels when bridged at 4Ω . Its 2-ohm stable design provides flexibility for a wide range of car audio configurations, while the variable high-pass and low-pass crossover controls allow precise system tuning. Speaker-level high-level inputs make integration with factory stereos convenient, while low-level RCA inputs support aftermarket head units. Built-in protection against short circuits, high temperature, and over/under-voltage helps provide reliable operation during everyday use.
