Rockford Fosgate R14X2 4" 2-Way Full-Range Speakers

The Rockford Fosgate R14X2 is a pair of 4-inch, 2-way coaxial full-range car speakers designed for replacing compatible factory speaker locations. Their compact format suits vehicles that use a 4-inch round speaker opening and need a straightforward audio refresh. Each pair includes grilles or trim rings and installation accessories for a more complete replacement package.

These speakers use a 4-ohm nominal impedance and are rated for 30 watts RMS and 60 watts maximum power handling. Their 100 Hz to 20 kHz frequency response supports midrange and high-frequency playback in a full-range speaker position. With 85 dB sensitivity at 1 watt/1 meter, they are intended for appropriately matched factory or aftermarket audio systems.

The R14X2 combines a vacuum polypropylene cone with a rubber surround to form its main driver assembly. A flush-mounted silk dome tweeter handles upper-frequency reproduction. An integrated tweeter high-pass crossover helps direct the appropriate signal range to the tweeter.

Rockford Fosgate specifies a 1.0-inch voice coil, 1 mm Xmax, 133.5 Hz free-air resonance, 1.22 Qts, and 1.0-liter Vas for this model. These published parameters describe a compact full-range coaxial speaker rather than a dedicated bass driver. For systems needing deeper bass, the R14X2 can serve as a compatible full-range speaker position alongside a properly selected subwoofer system.

Fitment should be confirmed before purchase using the 3.62-inch mounting diameter and 1.72-inch mounting-depth requirements. The speakers are sold as a pair and include grilles or trim rings, speaker wire, speed clips, and mounting screws. Read the included installation instructions and verify door, dash, or rear-deck clearance before mounting.

Design & Installation

The R14X2 uses a stamped steel basket, vacuum polypropylene cone, rubber surround, and flush-mounted silk dome tweeter. Its 1.0-inch voice coil and integrated tweeter crossover are incorporated into a compact 4-inch coaxial layout. Rockford Fosgate rates its speaker power handling in accordance with CEA-2031 standards and identifies this model as Verified with Klippel.

Confirm that the vehicle has a 3.62-inch mounting opening and at least 1.72 inches of mounting depth before installation. Check for window, lock, wiring, fuel-line, brake-line, and other obstructions before drilling; if new mounting holes are required, the installation guide specifies a 1/8-inch drill bit. Route wire before final mounting, observe positive and negative terminal polarity, and use the supplied trim ring and mounting hardware as appropriate.
