Tablecloths and door soundproofing – Soundproofing car doors is often the first step when we seek to increase the intensity of the bass and midrange tones and, at the same time, eliminate reverberations, resonances or, after a prolonged period, achieve a high sound pressure. Sometimes, replacing some speakers no longer makes sense. Soundproofing is achieved through the use of special self-adhesive mats that absorb sound, installed inside the vehicle’s door chamber. These mats are made of different materials, but the most popular are the butyl rubber-based ones covered with aluminum foil (to make them more rigid), since they are not too expensive and, above all, they maintain their properties in a wide range of temperatures (they work perfectly in winter and summer).

Mounting distances – It is true that we have already mentioned this, but it is worth mentioning again: these elements, usually made of MDF, are used in the mounting of speakers on sheet metal, as a separator and vibration absorber element. Thanks to its use, the transmission of vibrations to the sheet metal is not only limited, but practically eliminated.

Cables, i.e., speaker wires – Most factory car audio systems use 1.5mm² oxidized copper cables. In this situation, industry experts recommend opting for oxygen-free copper (OFC) cables, which are characterized by better conductivity, while discerning audiophiles immediately buy cables with larger cross-sections (2.5 to 4.0 mm), with a mixture of silver or made entirely of silver – which, of course, costs significantly more.
