Late-1990s Phoenix Gold QX2350 Chrome 2-Channel MOSFET Amplifier | New Old Stock (NOS) Vintage Car Audio

The Phoenix Gold QX2350 is a two-channel MOSFET power amplifier from the original late-1990s QX series, introduced before the range transitioned to its black-finish generation. Featuring distinctive chrome-style aluminium heatsink construction, gold-plated connections and adjustable crossover controls, the QX2350 reflects the bold styling and engineering of 1990s enthusiast car audio. With manufacturer-specified output of 125W × 2 at 4Ω, 175W × 2 at 2Ω or 350W × 1 bridged at 4Ω, it combines substantial power with flexible stereo and subwoofer applications. A nostalgic piece of Phoenix Gold history for collectors and enthusiasts of classic aftermarket audio.

New Old Stock (NOS) condition: Never installed or used beyond professional testing. The amplifier is preserved in pristine condition, accompanied by its original Phoenix Gold packaging & contents.

OSCA Fun Fact

The QX series didn't just disappear when car audio styling changed. By 2003, Phoenix Gold had replaced it with the Octane-R range, featuring design cues inspired by the street-racing scene. From the QX2350's chrome-era looks to the tuner-inspired styling of the early 2000s, even amplifier fashion was changing with car culture.

Built for the Sound-Quality Scene

During the 1990s, car audio enthusiasts were pushing beyond simple speaker upgrades, building elaborate multi-amplifier systems for sound-quality competitions and custom installations. Phoenix Gold became a familiar name in this culture, offering equipment recognised for distinctive styling and system flexibility. The QX2350 reflected this approach, with adjustable crossover controls, bridgeable operation and the versatility to power anything from component speakers to subwoofers. It represents an era when car audio was as much about the build as the music.
