About this product

4-Channel Class A/B Full-Range Amplifier, 75 W x 4 @ 1.5-4 Ω If you prefer a traditional Class A/B design taken to its highest possible level, the 300/4v3 is your amplifier, thanks to its outstanding fidelity, reliability and well-designed feature set. This classic amplifier features JL Audio's unique, and patented, Absolute Symmetry Class A/B circuit and our R.I.P.S. power supply design for full power delivery (75 W x 4) over a wide range of load impedances and vehicle voltages. This amplifier features an all-black look that is pure, sexy evil, including the powder-coated cast alloy heat sink and end caps.

Installation tips

• Size power and ground wire to the amp's current draw and fuse it within 18 inches of the battery.
• Keep the ground short (under 18 inches) to bare metal on the chassis.
• Set gains with test tones or an oscilloscope — the gain knob is not a volume knob.
• Mount it where it can breathe; amplifiers need airflow to stay cool.
