So I got everything in the car, all set up and being tested. The sound level difference between this enclosure and my old one is quite drastic, I had to turn it down. It's absolutely airtight, and light as a feather compared to the old one. I'm extremely happy as it all goes together with about a 1mm gap all around! I'll be pulling it all back out next week for final sanding, prep and paint. I've been trying to get this done right for 3 years now with so many setbacks and delays and it's finally coming together
I also have the mock-up done for the underhood wiring. fuse holder needs less crooked...
