Hyundai i30 N - soundproofing of wheel arches and doors + replacement of speakers

Soundproofing of the front and rear doors, front and rear wheel arches and replacement of factory speakers in a Hyundai i30 N. Most vehicles, Hyundai included, are prone to noise from the front and rear tires and road noise penetrating through the doors. Factory insulation is insufficient for strong low-frequency tire noise, and the same of course applies to the thin door sheet metal. Fortunately, it is relatively easy to reduce this noise with basic soundproofing without complicated disassembly of the vehicle interior. We soundproof the front wheel arches from the outside and can treat the rear ones the same way. It is always better to soundproof the wheel arches from the inside via the trunk area primarily because of the larger insulated body surface, but outside application also has a significant effect and the installation is naturally easier and faster. Door soundproofing is the foundation of any successful vehicle soundproofing.
