Rockford Fosgate T152 5.25" 2-Way Coaxial Speakers

The Rockford Fosgate T152 is a pair of 5.25-inch 2-way coaxial full-range car speakers for replacing compatible factory speakers. It is designed for vehicle locations where a compact speaker is needed without adding separate external crossover boxes. Each speaker uses a 4-ohm design and is rated for 60 watts RMS. The pair includes grilles, adapter plates, and mounting hardware for an upgrade-oriented installation.

This speaker set is suited to listeners replacing worn or limited factory 5.25-inch speakers and seeking greater power handling. Its 65 Hz to 22 kHz frequency response covers bass, midrange, and treble duties within a conventional full-range speaker position. The 1-inch aluminum dome tweeter handles high-frequency output. A built-in crossover directs high frequencies to the tweeter.

The T152 uses a carbon-fiber and polypropylene injection-molded cone with a butyl rubber surround. These materials are paired with Rockford Fosgate's VAST surround design and FlexFit basket construction. The result is a coaxial speaker assembly that combines the woofer and tweeter in one mounting location. This format can simplify an OEM-style speaker replacement compared with a separate component system.

An Integrated Concealed Crossover, or ICC, is built into the speaker assembly rather than supplied as a separate external box. The high-pass tweeter section uses a 12 dB-per-octave Butterworth crossover. This helps keep installation more compact while providing dedicated filtering for the tweeter. The offset cantilever-mounted tweeter places the high-frequency driver above the midrange cone.

For system matching, use an amplifier or receiver compatible with 4-ohm speakers and avoid exceeding the 60-watt RMS rating per speaker. The T152 can be used as a direct speaker upgrade in compatible 5.25-inch locations, subject to confirming depth and mounting-hole fit. Its 2.03-inch mounting depth should be checked against door, dash, or rear-deck clearance. Included multi-OEM adapter plates support select 5-by-7-inch and 6-by-9-inch mounting openings.

Key Features

• 5.25-Inch Coaxial Design: Combines midrange and tweeter drivers in each speaker.
• 60-Watt RMS Rating: Supports amplifier or receiver matching by continuous power rating.
• Integrated Concealed Crossover: Keeps the tweeter crossover within the speaker assembly.
• Aluminum Dome Tweeter: Provides dedicated high-frequency reproduction from a 1-inch tweeter.
• Carbon-Fiber Polypropylene Cone: Uses an injection-molded cone for the midrange driver.
• Included Adapter Plates: Adds mounting options for select larger factory openings.

Design & Installation

The T152 combines a carbon-fiber and polypropylene injection-molded cone, butyl rubber surround, aluminum dome tweeter, and polyurethane tweeter suspension. Its FlexFit basket design uses slotted mounting points to aid alignment during installation. Grilles or trim rings are included for a finished appearance where applicable.

Confirm that the vehicle has adequate room for the 5.25-inch speaker and its 2.03-inch mounting depth before installation. Observe polarity at the speaker terminals, use quality connectors, and route wiring away from sharp edges or moving vehicle parts. The package includes a pair of 5-by-7-inch and 6-by-9-inch adapter plates, but vehicle-specific fitment should still be verified.
