INSULATING FOR ACOUSTIC PERFORMANCE
When you shut your car door, does it ring like your old gym locker? You may have insulated your ride against heat, but how is it doing on sound problems? Sound or acoustic insulation is just as important as protecting against heat. And much like matching a gear ratio to the type of driving you do, using the right insulation is key.
