Professional Fitment Required: Electronic, electrical, and electromechanical components require correct identification before installation. Compare the new unit to the removed unit and verify mounting orientation, terminal or connector type, pin count or terminal arrangement, voltage rating, polarity, and any pulley or bracket configuration where applicable. Incorrect installation, polarity reversal, water or moisture ingress, improper connector seating, or mismatched specifications can damage the component, related ECU systems, or cause persistent fault codes. Installation by a qualified, VAT-registered workshop with appropriate diagnostic equipment is recommended.

Returns Notice: Once an electronic, electrical, or electromechanical component has been fitted, plugged in, energised, or shows signs of installation, returns are limited to manufacturing defect only. Confirm part compatibility before opening sealed packaging.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.
