Rockford Fosgate R1675-S 6.75" Component Speakers

The Rockford Fosgate Prime R1675-S is a 6.75-inch, 2-way component speaker system designed as a factory-speaker replacement for compatible vehicle locations. It separates the woofer and tweeter so the tweeters can be positioned independently from the midrange drivers. This makes it a practical choice for vehicle owners replacing aging or basic factory speakers while retaining a conventional car-audio layout.

Each system includes dedicated 6.75-inch woofers and separate 1-inch nominal tweeters. The woofers handle the main midrange and lower-frequency duties, while the tweeters reproduce upper frequencies through their integrated high-pass crossover design. With a 55 Hz to 20 kHz frequency response, the system is intended for full-range music playback in a properly matched vehicle installation.

The R1675-S is rated for 40 watts RMS and 80 watts maximum power handling. Its 4-ohm nominal impedance suits many aftermarket car-audio amplifiers and compatible factory or aftermarket radio systems. Use an amplifier or source unit that is appropriate for the speaker's continuous RMS rating and impedance.

Rockford Fosgate uses mica-injected polypropylene woofer cones with foam surrounds in this Prime component system. The woofers use stamped steel baskets, while the tweeters use Mylar balanced-dome diaphragms. These materials support a straightforward replacement-speaker design without adding unnecessary complexity to the installation.

The separate tweeters can be flush, surface, or angle mounted, giving installers options for aiming high frequencies toward the listening area. An in-line tweeter crossover simplifies the component connection layout. The R1675-S can be used as part of a front-stage upgrade and paired with compatible rear speakers, an amplifier, or a subwoofer system as desired.

• Mica Polypropylene Cone: Woofer cone material supports full-range playback.
• Mylar Dome Tweeters: Balanced-dome tweeters handle upper-frequency reproduction.
• In-Line Crossover: Tweeter high-pass crossover helps simplify system wiring.
• Multiple Tweeter Mounts: Supports flush, surface, and angle mounting.

Design & Installation

The R1675-S combines mica-injected polypropylene woofer cones, foam surrounds, stamped steel baskets, and Mylar balanced-dome tweeters. Grilles or trim rings are included for the woofers. Its CEA-2031-compliant power handling is rated at 40 watts RMS and 80 watts maximum.

Confirm vehicle fitment before installation using the 5.81-inch woofer mounting diameter and 2.00-inch woofer mounting depth. The tweeters require separate mounting consideration and have a listed mounting depth of 1.06 inches. Mounting hardware is included, and the tweeter can be installed flush, on a surface, or at an angle according to the available vehicle location.
