About this item

• Premium Material: Crafted from premium soft material, these car audio speaker washers boast excellent flexibility and waterproof performance, creating a tight seal with outstanding sound insulation. They hold up flawlessly in rainy, snowy, and windy conditions, ensuring long-lasting, failure-free use.
• Enhanced Stereo: These bass washers fill the gap between your speaker and door panel, absorbing unwanted door vibrations and noise to upgrade your audio system’s sound quality. They amplify bass expression significantly, delivering tighter, more powerful low-frequency tones for an immersive listening experience.
• Effective Noise Reduction: The washers block lateral sound wave propagation from the speaker, preventing standing waves from forming in door trim panels. This eliminates sound distortion and clarity interference, resulting in purer, crisper, and more precise audio output from your car stereo.
• Perfect Fit: Each package includes 4 car audio bass washers with an inner diameter of 5.53 inches and an outer diameter of 7.67 inches, specifically designed for 6.5-inch speaker upgrades. Tailored for door-mounted mid-bass speakers, they fit most car models on the market.
• Easy Installation: Featuring a strong self-adhesive backing, the washers can be installed in minutes—simply align them with the original speaker mounting points to avoid gaps (critical for optimal sound transmission), then press firmly to secure. Test the speaker after installation to confirm normal operation and enhanced sound clarity.
