It's comming along great! As for the resin smell if you have a high powered fan leave your trunk and doors open and let the fan air it out. That smell is gross and can last for a few days sort of like when your car sits in the body shop for while.
I built the first one in a crappy way though. I went to Lowes and got Elmer's Fiberglass resin and used about 10 sq yards of Bondo Mat. Before I start the other one I am definately ordering from uscomposites.com. I would have spent far less than I did on the first box. In materials for the first box I spent roughly $200 - Two gallons of resin at $37 each, 3 extra hardeners at $5 each, 10 sq yards of fabric at $7/sq yd. 1 yard of fleece at $6/yd, 1 70"X40" sheet of 3/4 MDF at $28. + about 50 hours of labor.
I also had to buy some tools (but I don't really factor them in as they are an investment) Ryobi Jig Saw $70, Dremel Rotary Tool $70. I have a router that I got from my grandfather years ago, but I think the router was built shortly after Ford released the mustang and the motor just didn't have the torque to cut through the MDF even with a new bit in it.
All being said, so far this had been a rewarding experience for me because I tackled something that I knew very little of and I am 95% satisfied with my first box. Soon as I finish the second box I want to try and get a little creative with fiberglassing and make a mount for my ipod and a mount for my Garmin GPS where the nav cubby is. I was contemplating making kick panels, but I dont want to mess with the fuse box and floor space is at a premium on the drivers side as I have a 6MT. I'm still trying to determin the best place to mount the tweeters for the Infinity Perfect 6.1 in the rear of my car (I know that rear speakers do not improve sound quality, but I have the Kenwood Dolby Digital & DTS processor and want to continue having surround sound for when I play DVDs).

uscomposites.com is much cheaper for better quality items. I got a gallon of B-440 Resin, extra 2 oz hardener, 10 yards of 1.5oz mat, and a roller for $69.45 plus $12 in shipping.

That's a good idea for the MDF on the bottom. The only MDF portion of my box are the rings. The total volume inside the box is about 1.75 Cubic feet which works fine with my sub. I originally planned to build it smaller, but I miss measured the basket depth of my sub and the ring is about 1.5" taller than orignally planned. I turned the volume up and it hits hard and clean so I'm happy with it.
Well, my supplies came from us composites today and man, working with the quality items from uscomposites over the bondo crap was so much easier and consistant. I put the mold back in the trunk to check the fit and I guess the heat may have warped it a little, so I crammed it into the trunk and got it to fit flush again, so I just layed down a layer of glass on it and will do 2 more tomorrow before I pop it out hoping that it will retain the correct shape.





B-440 Great stuff to work with.

I positioned the ring last night and tonight I will be trimming the excess fiberglass off for a clean edge and stretching the fleece over the rings with a layer of resin.
