### ⭐⭐⭐⭐⭐ Review
*by M***A on 30 August 2023*

Jamais j aurais pensé que ça ferait une si grosse différence. Il y a beaucoup de bruit (extérieurs, suspension, pneus...)se produisent au niveau de la valise et beaucoup de perte de son venant du système audio. Se produit de qualité règle tout ses problèmes, la voiture est beaucoup plus silencieux et au niveau audio on dirait que j ai installé un subwoofer dans la valise. Je le recommande fortement à ceux qui aiment la musique et qui déteste les "ratles" et vibrations de voiture . Bien suivre les indications et le résultat est impressionnant. Facile à installer.
