Crunch - 4 Channel 1000W A/B Class Stereo Amplifier & 2 Channel Amp & Wiring Kit - Black

This Crunch PX 1000.4 4 Channel Amplifier is a perfect entry level amplifier for your car audio needs. It has high quality circuit and hardware designs along with exclusive technologies to improve sound quality and minimize distortion.Crunch POWERX incorporates full Class A/B technology in stereo and 4 channel amplifiers along with Class D in the mono. Class A/B sounds better, but the PC boards require a bit more space that in other circuit topologies. With Crunch POWERX we have trimmed away some of the more esoteric features to deliver a great amplifier that sound like you would expect Crunch to sound. The POWERX line also includes Crunch technology like QTD (Quick Thermal Dispersion) Technology which puts more aluminum on the heatsink than a normal amplifier. QTD assures the amplifiers make huge power while running very cool with nearly undetectable musical distortions.

The Pioneer GM-DX874 four-channel amplifier delivers 100 watts RMS at 4 ohms to each of your front and rear speakers for powerful music. CTA-2006 compliant, this highly efficient Class D technology provides impressive, high-quality power in a compact chassis. The frequency response extends up to 50,000 Hz, supporting crystal-clear Hi-Res Audio Certified playback. The GM-DX874 uses high-grade electronic components and gold-plated RCA connections to ensure maximum performance. You can configure your amplifier into 3-channel mode (4 ohm loads) to create a strong front soundstage (2x 75 watts RMS) with tight bass from the bridged subwoofer (1x 300 watts RMS). The speaker-level inputs allow you to install this amp in a factory system without RCA connections. Built-in high-pass and low-pass filters let you optimize the sound for your vehicle's interior. A wired bass control remote also lets you easily control the amount of bass from the subwoofer output (SW).

Power your sound system with the Boss Audio Systems Monoblock Car Amplifier, engineered to deliver up to 1100 watts of dynamic audio performance. Designed for both casual listeners and audio enthusiasts, this amplifier combines power, precision, and reliability to elevate your in-car listening experience.At the core of this car amplifier is a high-efficiency MOSFET power supply. Using advanced Metal Oxide Semiconductor Field-Effect Transistors, the amplifier rapidly switches between full and non-conduction states, ensuring consistent power output with minimal energy loss. This results in cleaner sound and improved overall efficiency, even during demanding playback.Built with Class A/B topology, this amplifier offers the perfect balance between sound quality and efficiency. Its linear circuitry reduces distortion while enhancing clarity, making your music sound richer and more detailed across all frequencies. Whether you’re pushing deep bass or crisp highs, this mono amp maintains precision and control.The amplifier is 2-Ohm stable, allowing it to safely power subwoofers or speakers at lower impedance for increased output and volume. With both high and low-level inputs, it integrates seamlessly into factory or aftermarket audio systems, making upgrades simple and flexible.Fine-tune your sound with a variable low-pass filter and switchable bass boost of up to +18dB, giving you full control over low-frequency performance. The variable input control ensures optimal signal matching for peak performance.Designed with protection in mind, the amplifier features automatic short and thermal protection, shutting off if overheating or faults occur to safeguard your system.
