Just reread your post. It wasn't so much a box I molded the fiberglass around as literally a frame for a picture. I think I used something like 2x2 wood cut the length of the transmission well. I used only as thick of wood as I'd need to sink the screws from the top into.

It's been so long since I did it that I'm having trouble remembering the details. I'll get it out of the car over the weekend and I"m sure it will all come back to me.

[QUOTE=JustJeff;131578I was doing it in the summer so I'd do a few layers and set it in the sun to bake a little. Then come back and do more.[/quote]

Really? Do you remember what brand you were using? Most of the poly resin that I use, even the West System stuff will kick off in about an hour.

yeah, that would be the biggest concern for me too.

One thing to keep in mind though. This is my second box I've made for that same location. I originally made a box for a JL 10" sub and it was a poor choice. JL subs..um..W3 and up are great subs but that was a poor location for them. You are limited with how much airspace you can give them. Also the pressure from the speaker was rattling all that flimsy molding where the top folds down.

Later I scored a Boston Pro 8"...after much looking. I specifically was looking for that one for it's reputation. I've always loved Boston Pro speakers and the 8" is well known for needing minimal volume for great sound. IIRC it only needs .5 cubic feet of volume in a sealed box. The tighter sound of an 8" sub works much better under the rear deck. That's all IMHO. I personally hate subs that rattle the car. I'd much rather hear a tight, accurate bass than try to peal the pavement with SPL and shitty unbalanced music that is so bass heavy the other sounds from the music are muted in comparison.

Getting back to the box. I've had zero issues with it since it was completed. I'll post up some pics of it tomorrow or over the weekend.

I love me some Boston Pro's, I've been thinking about swapping out my 10" shallow mount Alpine for a Boston.....

No need to take anything apart, although I do appreciate it, a few pics of the finished product will do just fine. Thanks again, I appreciate it.

I've still got most of the resin I bought in storage. I'll be there tomorrow or sunday to do some engine rebuild stuff. I'll write down the brand and get back to you on that. It does start to setup quickly. IIRC between coats I was setting the enclosore in the sun no more than half hour or so at at time, then adding more.

The Boston Pro subs were/are amazing. Boston Acoustics has since changed the product line around. They are no longer making the Pro's..or at the least not putting the "Pro" label on them. Now they have a few product lines from entry level clear up to competition class rebuildable subs. I'm not sure where the "Pro" would fall in their new product line. I kinda got my system to where I wanted and stopped learning what was what.

The 8 is simply amazing. No one believes it an 8 till I show them. It hits like a 10 or 12. It doesn't get the low SPL levels of a 12, but it's much more clear and accurate. There is no muddy bass with it. If you can find one jump on it cause they are no longer made and have to be at least 4-5 years out of production.

And no worries, I didn't need to take anything apart..I found pics saved on my hard drive. But this thread is a great reminder. The sub has been sitting in my car which hasn't been driven in over a year. I need to get it out anyway and simply make sure it's still in good shape. My vert has the typical water leaks so I maintain where that water pools.
