Hey cool post. Extremely helpful..How to Make a Fiberglass Enclosure - Page 3 -- posted image.. I have a question for ya as a shop what does something like this cost? I have donen some glass work but in my current building my landlord prohibits this as he is a sissy. I'm always curious on what a larger higher volume place would charge. Last time I did glass the materials were expensive.  Again great post it has some awesome information, ever think about writing how to books?

Thanx again Jeff

Hey Jer, the job cost the customer about $ 1200 with paint, supplies & labor. The customer brought me the equipment and the car ans I just did installed and fabricated the enclosure. This job took about 1 week to accomplish. The sanding took about 3 days of the week !!

cool thats pretty close to what I was thinking.  I was just curious, I've had couple of requests for glass work last night in fact client wanted 2 subs mounted in subarau firing into the back corners of  the trunk.  the enclosures were to hold 2 audiobahn competition subs and then flowing into an amp rack on each side.  cool idea lots of work. I quoted him $1700 total, had to get out my defibrilator and bring him back. I don't think he realized how much work it is. Thanx for the info.

hey, since you made the cover for the  box do you really need to sand down the actual box? or does it make shaping the cover easier?

It makes the mold for the cover alot easier to make with less imperfections to work out later. Sanding it smooth reduces sanding time for the cover by more than 1/2 & also allows you to shape the enclosure more to what you want it to look like.

I'm still trying to figure out how to attach the cover without it rattling. As far as the rattling goes how could ya allow for some room for sound dampening if desired? I've been interested in building FG box with a cover, just haven't really pondered on how. By the way great thread, very informative.
Slowly but surely working towards something. Not sure what though.

I see that the way you did it you used 1 sheet of fleece. but the enclosure doesnt fill up the whole trunk etc.. How could you make a cover for a trunk of a i.e Bmw m3 to the weather shield so you dont see anything oem. just fiberglass and the equipment?

We always use MDF for our enclosures but you can use anything that will be dense enough and also must withstand the sub's pressure.

IF there are any rattles on the cover you can use a stick on foam ( kind of like sound deadening ) on the backside of the cover to add weight.
