Put them in my tacoma that is sound treated but had a hollow sound that drove me nuts now the sound is so much better enjoyable clear
I was skeptical about these for what they cost and if they actually make a difference but very happy with the outcome. My truck is heavily sound treated bit even after adding these black hole tiles I noticed even more of a difference. My system has always been very clean clear and precise but it now sounds even better most noticeablely at higher listening volume levels after installing the tiles
This is a great alternative to doing a whole door with dynamat. Saves weight and improve sound and back waves. I was impressed by this product. Lack Hole Service was quick and easy. Delivery is very fast. Something that I wasn’t sure when I order this product.
