Bring clear, efficient sound to your vehicle with the Ground Zero 4 Inch Radioactive Coaxial Speakers GZRF 4.0SQX, part of the Radioactive series. This compact 2 way coaxial speaker pair is designed for drivers who want a strong upgrade from factory speakers without sacrificing installation flexibility. With a 100 mm 4 inch woofer, 3 ohm impedance, and integrated crossover, these speakers are built to deliver punchy, detailed audio performance in a space saving format.

The GZRF 4.0SQX combines a black circular brushed aluminum cone with a rubber surround and Conex spider for responsive midbass and long lasting durability. A 25 mm 1 inch silk dome tweeter adds smooth high frequency detail, while the ferrite motor and resonance free steel basket help maintain stable performance and reduce unwanted vibrations.
