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 by Luxury Liner Pro

FAQ

What is the difference between Overkill and Overkill Pro?
Overkill and Overkill Pro are both made from the same exact closed cell foam. The difference is in the total thickness and weight.

Overkill is 1/8 inch thick
Overkill Pro is 3/8 inch thick

The extra thickness and weight that comes with the Overkill Pro makes it superior to regular Overkill.

What is the difference between Luxury Liner and Overkill Pro?
Luxury Liner is a noise barrier
Overkill Pro is a noise absorbing filter.
Both products get applied on top of vibration dampers like Damplifier Pro or Spectrum in order to reduce airborne sound waves, but they do it in two totally different ways.

Overkill filters out specific frequencies that are able to penetrate the first vibration damping layer, but because it is so light, it allows many other sound wave frequencies to pass right through.

Luxury Liner is a barrier that blocks and reflects the most difficult airborne sound waves that Overkill Pro is not capable of handling.
