Car audio enthusiasts and DIY speaker builders, these 4x6 speaker grill covers are exactly what you need to protect your investment while looking good doing it. Each grill features a sturdy ABS plastic frame with durable metal mesh that stands up to accidental bumps and keeps curious fingers away from your delicate speaker cones. Measuring 7.4 inches long by 4.8 inches wide with a 0.55-inch thickness, they're perfectly sized for standard 4x6 speaker openings. The diagonal mounting hole distance is 143mm (5.6 inches) with 4mm screw holes, making installation straightforward with the included tapping screws. Here's a pro tip though - after you install the screws, add a small amount of glue where the mesh meets the frame to prevent vibration from loosening things over time. The black finish looks clean and professional in any vehicle or home audio setup. This 2-pack means you can protect both front speakers or have a spare on hand. Whether you're upgrading your car audio system, building custom speakers, or just want to replace worn-out factory grills, these covers deliver protection without sacrificing sound quality. They're easy to clean too - just wipe with a damp cloth when needed. Seriously, for the price, you're getting professional-level protection that keeps your speakers looking and sounding great for years to come.
