Pioneer GM-X544
Multi-channel amplifier
Pioneer's amplifiers are designed to keep your music loud and clean, given the less-than-perfect conditions of car audio. They feature Pulse Width Modulated power supplies with MOSFET switching, high-voltage input control, heavy duty MOSFET output, and noise-cancelling input circuitry to ensure you get full power even when your car's electrical system is loaded down. They're stable all the way down to 1 ohm in stereo (or 2 ohms with the amp bridged to mono) so they'll hit hard in a wide variety of situations.  Built-in high- and low-pass crossovers permit precise tailoring of your system to your sonic taste. Gold-plated preamp outputs make it a breeze to add other amps. Pioneer builds versatility and performance into these amplifiers so that they'll be working hard in your car for years to come.
