Started for car audio competitors in Hamilton

Its timeline lists global distribution from 2000, an expansion of the Ohio headquarters in 2015 and the ProX line in 2023, and it now claims more than 3,000 dealers in over 30 countries. The same timeline marks 2026 with "Now Family-Owned."

What the Made in USA claim covers
Dynamat's homepage lists Made in the USA among its core claims and says its products are "engineered in the U.S.A. to stop noise, vibration, and heat at the source." The Xtreme Door Kit page carries the same branding.
The products we list are all Dynamat Xtreme: the bulk pack, tech pack, installer pack, hex pack single sheet and the pre-cut door kit. Dynamat does not give a separate factory address, so we can confirm a US origin for these mats but not the exact plant. We found no imported line on its site.
