Over Kill Pro™ is a very flexible OEM style foam made of closed cell vinyl infused with rubber, specifically engineered to absorb airborne noise in your doors between the frequency range of 15k Hz and 20k Hz. It is 3 times thicker than our regular Overkill mat and will do 3 times the work.

Sheet size = 24" x 54" (9 sq. feet)
Thickness = 3/8" (.375")

Noise Reduction Uses...
Many people use closed cell foam materials like Overkill Pro on top of vibration mats, but this does very little for noise reduction.
Unfortunately there are several companies out there marketing cheap closed cell foam as noise barriers, and we are left to combat poor marketing by educating our customers on how things really work.
Mass is key when reducing airborne noise, and closed cell foams simply do not have the mass that is required to effectively do the job.
For reducing airborne noise, Overkill Pro will help some, but not nearly as much as our barrier product Luxury Liner and Luxury Liner Pro.

Mobile Audio
Applying a layer of Overkill inside the doors on top of your Damplifier or Spectrum vibration dampers is the easiest way to improve the acoustics from your door speakers.
First, Overkill Pro will reduce the airborne sound waves that are able to penetrate the vibration damper. This reduction in unwanted noise will equate to in increase in the desired noise which is your music.
Overkill will also reduce the intensity of distortion causing reflections inside your vehicle. The less noise that is bouncing around the car walls, the louder and clearer your audio system will sound.
Thermal Insulation
Anything you place in front of the heat source will help reduce or slow down the heat. Overkill will help reduce heat to a small degree but is not specifically designed to do so. Any heat reduction noticed from Overkill is purely a side benefit, not an intended result.
For The ultimate in heat damping protection, use a combination of Damplifier Pro followed byLuxury Liner Pro
