The Pioneer GM-DX874 four-channel amplifier will deliver up to 150 watts RMS to each of your front and rear speakers for powerful music. Highly efficient Class D technology keeps this powerful amp running as cool as it looks, and allows for a compact chassis that fits in a lot of out of the way spaces. The frequency response of this amplifier stretches up to 50,000 Hz, for Hi-Res Audio Certified playback. Pioneer uses high-grade electronic parts and gold-plated RCA connections to ensure maximum performance. Speaker-level inputs allow you to install this amp in a factory system with no RCA connections. The amplifier switches its input mode automatically when it detects the high-level signal, eliminating the need to run a turn-on lead to your receiver or fuse box. Built-in high- and low-pass filters let you adjust the sound for your vehicle's interior, whether you're driving speakers or subs.

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.
