The Ground Zero Sound Upgrade 4x6-Inch Coaxial Speakers are designed to bring a clear, punchy upgrade to factory audio systems without the complexity of a full custom install. Part of the Sound Upgrade series, this 2-way coaxial speaker pair is built for drivers wanting more detail, stronger midrange response, and improved overall clarity from a compact speaker size that suits a wide range of vehicles.

Each speaker features a coated paper cone with a rubber surround and a resonance free steel basket for stable performance and reduced unwanted distortion. The integrated crossover helps the 13mm Mylar tweeter blend smoothly with the woofer, while the fixed tweeter design keeps installation simple and reliable. With a sensitivity rating of 89dB, these speakers can deliver solid output even when powered by a standard head unit, making them a practical choice for an easy sound enhancement.

Rated at 70W RMS and 110W max, the GZCS 46CX speakers offer dependable power handling for everyday listening with enough headroom for fuller, more dynamic playback. The 4 ohm impedance, 80Hz to 20kHz frequency response, and 48mm mounting depth make them a versatile fit for many applications. Supplied as a pair with grilles included, they are ideal for replacing tired factory speakers with a tidy, high quality audio solution.
