Hinnant Designs does solid work! He’s worked on 3 different cars of mine now. He has done 3 different stereo upgrades that work flawlessly and no corners are cut whatsoever on his other builds. He does quality work and makes a happy customer every time!

I own a very custom dodge challenger, and I am very picky when it comes to selecting items for my car. I am very into the details, from how it looks to how it sounds. Throughout the entire process, starting with the design of the boxes and throughout the install, Hinnant Designs knocked it all out of the park!

I was pleased with the constant communication on sharing ideas for the custom fabrication of the box design, ensuring that its function would not only look good but fit my needs of being easily removable. While my vehicle was going thru the installation process, I was given constant updates, and at no time did I worry the project was not going to be completed exactly as outlined beforehand.

His knowledge of the equipment is top notch, and my audio quality has drastically increased! I look forward to doing phase two of my audio needs for my vehicle, and cannot recommend Hinnant Designs enough! If you are looking for great communication, staying on the outlined budget and timeline, and superior service, don’t hesitate! Hinnant Designs will have you extremely satisfied!

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.

I called Howard and asked for some help regarding a DSP purchase, he not only helped me with that but we had a nice talk regarding tweeter less 3-way car audio installs and he made some knowledgeable recommendations.

I can tell he knows the products/industry he represents very well and isn’t just selling or installing stuff to make a quick buck.

I would recommend him and his company to any of my friends (family not into car audio so n/a, haha) for their SQ needs.
