New to the forum! Just wanted to share my recent project for anyone else that needs any ideas! Audi TT rear seat delete custom fiberglass box with 2 Kenwood 12" powered by the Kenwood KVT-512 flip out with a Kenwood 800w 2 channel amp. I have about 80 hours and about 500$ into the box alone. Here are the pictures of the whole project along the way! It was painted with rhino liner and the texture and color match the interior panels perfectly! The last step I have is to put the crossbar in but check it out and let me know what you think!

Since it would be in the trunk I decided to use spray on bedliner in a can so I could easily fix it and it would be durable. Some recommended against it but I came out perfect with not a single run or imperfection.
