After taping off and wrapping in aluminium foil does the cover that you create come off easily?

Just a rookie out to learn some more

I was wondering how the top peice stays on the box, and also how did you place the secone ring on the foil before you fiberglassed again. The description is very good and want to try it on my 2000 gmc jimmy with 2 subs.

I know you have probably been asked this question alot but how do you determine the volume for a fib'ed box and i have know idea with all the fancy lingo to be honest is there just a way where you can build the chamber to about the same dimensions as a regular box....

-width of chamber, then the height of the circular ring, or something..

Use this link for volume calculations.

Hi, I am new to this site as you can see and I am loving the amount of detail that the membere here post....

But anyways, just a quick couple of questions about the encloseure that you built,

1. What is the reason for the cover that you built, can you paint on the original enclosure or do you heed to make the cover to put over the box in order to paint, from what I am thinking , it seems like the reason for it is for less sanding and preo time... But dont know for sure.

I did this because I wanted a flush look for the amplifier and the subwoofer. I couldn't flush the amplifier because the mounting holes were wider than the face of the amp. By making a cover peice I was able to cover the screws and flush the amplifier face.

2. Did you put fiberglass on the sides of the enclosre and on the bottom????

Just on the side. The bottom was made of MDF and did not require fiberglassing.

3. Is there any need for some wood screws for the braces or is wood glue and super glue addaquate????

Super glue was adequate as the frame would add the support required.

4. What is the general cost on just the fiberglass materials... Minus paint, mdf, etc. just like resins and mat and other needs for fiberglassing only, plus roughly how much resin and matt did you end up using for this project, im assuming alot by the looks of it....

THe cost was about $ 75-100 depending on where you get the materials or what kind of deals you get from a supplier.

5. Is there any internet websites on where I can purchase all of this, I've read that home depot has some stuff, never looked, but from what I read it was elmers brand, is that any good???? I know of autobodydepot.com, which is a great site for paint and abrasive needs,but never came accros fibergalss stuff, maybe i wasnt looking hard enough... But thanks alot!!!!

There are alot of places online that you can get this stuff, but try your local marine shop or even Wal-Mart.

yes it comes off with ease. It's a little snug because it's friction fitted, but should come off without prying.

The cover peice is friction fitted. The part that I didn't put on there was that I used 1/4" sticky foam tape to reduce vibration and also added to the fittment of the cover. As far as the second ring, the enclosure was flat and I just rested the ring on the enclosure and it did not move. If your going to be designing a vertical enclosure I suggest spray glue to hold the ring into place.
