Frequently Asked Questions
Quick answers to your questions
Professional soundproofing installation preserves your vehicle's original wiring and structure, ensuring no impact on the 4S warranty. However, for vehicles still under warranty, we recommend confirming specific terms with the 4S dealer before starting work.
All LCFX products use eco-friendly butyl rubber and EVA materials. SGS-certified, odorless, and safe even under high-temperature exposure with no harmful fumes released.
Four-door soundproofing takes approximately 2-3 hours, while full-vehicle soundproofing (including floor, trunk, and hood) takes about 6-8 hours. Actual time varies by vehicle model and installation complexity.
Whole-vehicle soundproofing reduces cabin noise by 3-8 dB, with actual results varying by vehicle model and original insulation. Improvements in wind and road noise are most noticeable at high speeds.
Some simple areas (e.g., trunk, hood) can be DIYed. However, door panels and undercarriage work require removing interior trim; we recommend professional installation to ensure quality and warranty coverage.
The total weight of the vehicle's sound-deadening material is approximately 15-25 kg, with a negligible impact on fuel economy (about 0.1-0.2L/100 km). The resulting improvement in cabin quietness is well worth it.
Out-of-warranty paid repair services are available, including material replacement and installation adjustments. For specific costs, please contact an authorized dealer or official customer support.
Genuine LCFX products feature an anti-counterfeiting QR code on the packaging. Scan it to verify authenticity. We recommend purchasing and having installation done through authorized dealers to avoid counterfeit products.
