Rockford Fosgate Prime R675 Coaxial Speaker

Product Overview

The Rockford Fosgate R165X3 from the Prime series is a high-value 6.5-inch 3-way coaxial speaker set engineered to replace dull factory speakers with legendary Rockford Fosgate clarity, punch, and detail. Designed as a direct drop-in upgrade for standard 6.5-inch factory locations, this 3-way full-range speaker delivers dynamic full-frequency reproduction across your entire cabin.

Vacuum-Formed Polypropylene Cone & Rubber Surround

For punchy mid-bass impact and articulate vocal reproduction, the R165X3 features a durable vacuum-formed polypropylene woofer cone. Supported by a flexible rubber surround, the driver maintains smooth, linear excursion during high-volume playback, resisting environmental moisture and cabin heat over years of daily driving.

Multi-Driver 3-Way High Frequency Array

High and ultra-high frequencies are driven by a dual-element high-frequency bridge mounted directly over the woofer pole. A 1/2-inch silk dome tweeter delivers smooth, fatigue-free mid-high response, while a dedicated piezo supertweeter restores top-end shimmer and acoustic brilliance.

Integrated Crossover & Easy Factory Fit

To streamline installation, the R165X3 features an integrated High-Pass crossover network built directly into the driver frame, eliminating the need to mount bulky external crossover boxes behind door panels. Housed in a stamped steel basket with a shallow mounting depth, these 4-Ohm speakers drop easily into standard factory door cutouts or rear decks.

Frequently Asked Questions (FAQ)

Q: Will the Rockford Fosgate R165X3 speakers run fine on a factory stock stereo?

A: Yes! Thanks to their high 91 dB sensitivity rating, the R165X3 speakers are very efficient and play loudly and clearly directly off a stock factory radio or aftermarket head unit without requiring an external amplifier.

Q: Do I need to buy separate crossover boxes to install these 3-way speakers?

A: No. The high-pass crossover network is built into the speaker assembly itself, making installation as simple as connecting your vehicle’s two positive and negative speaker wires directly to the frame terminals.

Q: Are protective speaker grilles included in the box?

A: Yes, the Rockford Fosgate R165X3 set comes complete with a pair of stamped steel protective grilles with black mesh and Rockford Fosgate badging for custom surface-mount installations.
