Description
MTX THUNDER75.4
400-WATT RMS 4-CHANNEL CLASS A/B AMPLIFIER
Small in Size, Big in Power
The THUNDER75.4 is a 400-watt RMS amplifier designed to be installed in almost any vehicle due to its small chassis size. Its power capability and wiring versatility makes it a perfect choice for running multi-channel speaker systems without compromising musical output or quality.
Technologically Advanced
This amp features a Class A/B circuit design that delivers high fidelity sound output meaning you can enjoy your music as the artist intended it to be heard.
FEATURES
• Compact Design - The small footprint chassis allows for installation in space challenged vehicles
• Surface Mount PCB Design - Decreases chassis size, improves layout efficiency and increases vibration resistance without sacrificing performance or sound.
• Variable Butterworth Crossover - a 12dB/Oct crossover that allows you to set the frequency your speakers will play down or up to
• Triple Protection Circuitry - Thermal, DC Offset, and Short Circuit Protection circuitry ensures the amplifier will protect itself in the event of a problem
• Extruded Aluminum Heat Sink - The custom heat sink design maximizes heat transfer away from the circuitry protecting the amplifier
• Noise Free Design
• MOSFET Power Supply
