"longDescription": "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.",
