Rockford Fosgate T1SG-12 12" Slim Subwoofer Grille

The Rockford Fosgate T1SG-12 is a protective 12-inch mesh grille made for select Power Series T1 slim subwoofers. It helps shield the subwoofer cone and surround from accidental contact in exposed vehicle installations. This is a passive accessory rather than a speaker, amplifier, or powered subwoofer.

It is intended for owners of compatible Rockford Fosgate T1 slimline 12-inch subwoofers who want added physical protection without changing their existing enclosure or electronics. The grille is designed to integrate with the subwoofer's removable trim ring. That makes it a practical addition for trunk, cargo-area, under-seat, and other exposed installations.

Because the T1SG-12 is a grille insert, it has no RMS power rating, impedance, or sound output of its own. Its role is physical protection for the moving cone and surround rather than altering the subwoofer's electrical performance. Use it with a properly installed compatible T1 slim subwoofer and its original trim ring.

The grille uses a stamped steel mesh construction with a black finish. Its formed profile is made to sit within the trim-ring arrangement used by compatible T1 slim models. Rockford Fosgate notes that the grille adds approximately one inch to the subwoofer's mounting height.

For a Power T1 slim subwoofer system, the T1SG-12 is an accessory upgrade that can be added after the subwoofer is installed. It is specifically listed for the T1S1-12 and T1S2-12 12-inch slim subwoofers. The package includes one grille, an owner's manual, and a mounting diagram printed on the back of the packaging.

Design & Installation

The T1SG-12 uses black stamped metal mesh formed as a grille insert. Its design is intended to work with the factory-style removable trim ring on compatible Power T1 slim subwoofers. The steel mesh construction is intended to protect the exposed cone and surround from incidental impacts.

Installation involves removing the compatible subwoofer's existing trim ring, positioning the grille insert, and re-securing the trim ring. Confirm that the subwoofer is a T1S1-12 or T1S2-12 and allow for the approximately one-inch added mounting height before finalizing enclosure clearance. No wiring, power connection, or amplifier adjustment is required for this passive grille accessory.
