The SoundSkins Pro Mega Kit gives you 44 sq ft of 3-layer sound deadening for projects bigger than a pair of doors. Each sheet bonds rubber butyl, foil and closed-cell acoustic foam into one material, so you can quiet all four doors, the trunk and more without buying and layering separate products. It is also a lower cost per square foot than the smaller Pro kits, which makes it the practical choice when you are treating most of the car.

Pick the Right SoundSkins Pro Kit
Every Pro kit uses the same 3-layer material. The only difference is how much you get and what you pay per square foot:
Buying four Two Door Kits to get the same coverage would cost $496. The Mega Kit gets you there for $412.
What 44 Square Feet Covers
Exact coverage depends on your vehicle and how much of each panel you treat, but in a typical sedan the Mega Kit handles all four doors (outer skins and access holes) and still leaves plenty for a second area, such as:
-
The trunk: Trunk floor, wheel wells and the trunk lid, where a lot of road and exhaust noise gets in and subwoofers cause rattles.
-
The front floor: Driver and passenger footwells, where tire noise and heat come through the floor pan.
-
Rear doors and quarter panels on trucks and SUVs: Larger doors and open cargo areas use more material, and the Mega Kit gives you room to cover them properly.
Planning the whole car, roof included? The Pro Plus Kit is sized for that.
One Material Instead of Two
Traditional sound deadening takes two steps: a butyl mat to stop panel vibration, then a separate foam layer to block airborne noise and stop rattles. SoundSkins Pro combines both. The butyl adds mass and kills resonance in thin sheet metal, the foil holds it tight to the panel, and the closed-cell foam on top absorbs noise and cushions trim panels. That means fewer steps, fewer products to buy and an install you can finish in a weekend. Learn more about how SoundSkins Pro works.
Tips for Large-Area Installs
-
Work at 50°F to 70°F. This is the recommended application range for the best bond.
-
Make paper templates for floors and trunk panels. Big, curved areas are easier to cut accurately from a template.
-
Clean every surface with isopropyl alcohol to remove dust and oil before applying.
-
Roll it down firmly so the butyl makes full contact with the metal, especially on ribbed floor pans.
-
Leave drain holes, seat bolt holes and wiring paths clear so nothing is blocked when you reassemble.
Frequently Asked Questions
How many doors does the Pro Mega Kit cover?
All four doors on a typical sedan, with material left over for the trunk or front floor. Larger truck and SUV doors use more material per door.
Can I use it on the floor and under carpet?
Yes. At 0.18" thick, it sits flat under factory carpet and helps block tire noise and heat coming through the floor.
Will it hold up in hot weather?
Yes. SoundSkins Pro is rated from -40°F to 356°F, so it stays in place in hot trunks, on floor pans and in summer heat.
Is it better value than buying smaller kits?
Yes. At $9.36 per sq ft, the Mega Kit costs less per square foot than the Two Door or Four Door kits and saves $84 compared to buying four Two Door Kits.
Is there a warranty?
Yes. SoundSkins sound deadening products come with a lifetime warranty against manufacturer defects.
