Thanks for sharing

Thank you!
The box is covered with high grade vinyl. It’s so good I have a hard time telling the difference from it and the leather. The smell give it away.

I didn’t do the upholstery but did cover some of the wood parts myself. The tough pieces I had my upholstery guy do.
Check out my build thread it has more pictures of the stereo and interior.
