Hinnant Design is the one-stop shop for anything audio. The specialty of this shop is producing high-quality customization of audio and integrating the system flawlessly with OEM counterparts. The customization blend in perfectly and never looks incompatible/out of place with the rest of the interior. The owner Howard is the kind of business owner that genuinely cares about his customers. His technical capabilities combining with his enthusiasm and patience make him the kind of fabricator/business owner I like dealing business with. I recommend this shop to people in DMV area for high-end audio customization.
