Installing the Q-Mat Sound-Shield to your doors can make the biggest difference to reducing noise inside your car.
It improves the sound from car speakers, reduces noise from outside and prevents the door panels themselves from causing
vibration and resonance.
When you close the door, you feel and hear a satisfying thump - the same as luxury cars.
It is advisable to install Q-Mat to both inner and outer skins of the door for maximum effect.
Generally, you will need 2 sheets per door depending on the size of your doors.
