Experience exceptional power and clarity with the Hifonics 1,000-Watt Super Class A/B 4-Channel Car Audio Amplifier, designed to deliver deep, dynamic sound to your speakers and subwoofers. With flexible 4-channel operation, you can customize your setup in stereo or mono bridged modes, giving you full control over your car’s audio performance. The variable electronic crossover and electronic equalizer allow for precision tuning, so every note and beat sounds exactly as intended.

Built for performance and durability, this amplifier delivers 4 x 250W at 2 ohms, 4 x 125W at 4 ohms, or 2 x 500W bridged at 4 ohms, ensuring reliable output for any system. The Ultra-Fi MOSFET output device technology and classic Hifonics aluminum construction provide efficient cooling, powerful sound delivery, and minimal distortion—even during extended play.

Enjoy clean, efficient connections with secure molded terminals and high-temperature, impact-resistant, nickel-plated connectors that resist corrosion and ensure stable signal transfer. The Pulse Width Modulated (PWM) power supply maintains constant voltage for consistent audio output, while built-in overload and short-circuit protection with illuminated indicators keep your system safe and performing at its best.
