The T1SG-12, a Power series stamped steel mesh grille, seamlessly fits into T1 10" slimline subwoofer trim rings. Crafted from stamped metal, this black grille safeguards your 10" T1 slimline subwoofers from harsh conditions behind or under your truck seat. It shields your prized Rockford Fosgate subwoofers from softball bats, hockey sticks, and random clutter. To install, simply remove the existing trim ring, insert the mesh grille, and re-secure the trim ring. Compatible with select models.
