Important Safety & Mounting Precautions:

• Secure Mounting: Ensure brackets are firmly anchored to a solid structural surface using suitable hardware. In the event of a collision, sudden braking, or off-road driving, unsecured speakers can become dangerous projectiles.
• Care When Drilling & Screwing: Always inspect behind dashboards, kick panels, or bulkheads before drilling holes or driving fasteners. Ensure you do not puncture electrical wiring harnesses, fuel lines, brake lines, or structural components.
• Avoid Obstructions: Position enclosures so they do not obstruct driver sightlines, pedal travel, steering operation, gear levers, handbrakes, or glove box openings.
• Occupant Clearance: Mount speakers clear of head-impact zones and airbag deployment pathways.
• Note: For internal / inside use only, the speakers are not weather or water resistant.
