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

Sound deadening of front and rear doors, front and rear wheel arches and replacement of factory speakers in Hyundai i30 N. Most vehicles, including Hyundai, are prone to noise from front and rear tires and road noise coming through the doors. The factory insulation is short on high low-frequency noise from the tires, and of course the same applies to the thin door sheet metal. Fortunately, it is relatively easy to reduce this noise with basic soundproofing without complex disassembly of the car's interior. We soundproof the front wheel arches from the outside, and we are able to soundproof the rear ones in the same way. It is always better to soundproof the undercarriage from the inside of the trunk, mainly because of the larger area of the soundproof body, but the application from the outside also has a significant effect and installation is of course easier and faster. De-sounding the door is the basis for every successful car soundproofing.
