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.

Technology
R.I.P.S. - Regulated, Intelligent Power Supply

The remarkable R.I.P.S. System ensures consistent power delivery over a wide range of battery voltages and load impedances.

Advanced Rollback Protection

JL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down events.

Absolute Symmetry Class A/B Circuitry (U.S. Patent #6,294,959)

Patented Absolute Symmetry Class A/B output stage delivers amazing fidelity with extremely low distortion over a wide range of load impedances.

RealSink™

Vertical, cast alloy fins effectively dissipate heat, without resorting to noisy fan-cooling.

Differential-Balanced Inputs

JL Audio's Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. This technology allows for the use of conventional RCA cables, while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
