  2. 2

    Research the various types of soundproofing materials available. Visit an auto parts store and do research online as well. Soundproofing materials for cars and trucks can be divided into three categories -- bonnet and boot insulation materials, which may be some type of matting or combination of foam rubber and cloth; noise barriers, made from multiple layers of compressed cotton or a similar material; anti vibrating material, which is glued to panels to stop panel vibrations and to reduce low resonance road noises.

  3. 3

    Open the bonnet of your vehicle. Clean the underside of the bonnet with an all purpose cleaner to remove dirt and grime. Measure the width and length of the bonnet and cut your bonnet lining material into two strips. Apply an adhesive to the bonnet and to the bonnet liner. Attach the bonnet liner to the bonnet and allow the adhesive to dry for the recommended period of time. The same procedure may be used for the boot as well.

The noise barrier material attaches to the firewall underneath the carpet of the car with a contact adhesive. sells several different versions of flexible foam floor barriers that sit underneath the carpet on the floor of the car and in the boot as well that blocks low frequency road noises.
