Any fiberglass box tips?

I will be attempting my second attempt at a fiberglass box. The first went horribly wrong; needless to say I didn’t do any research before hand. The second attempt will be in place of the spare tire of a 1986 Ford Mustang. If you have any tips in order for me to do this they would be greatly appreciated. Also any pictures could be of help.

read every post on this forum, then... read them again. there is soooo much info here from some VERY tallented people. good luck.

I second that. But to help you get started, I'll pop some tips for you here; save you some time ^-^

throughout the area that you are going to mold the bottom of the enclosure, lay some masking tape down and go out at least 3" extra from where you plan to stop the box. I recommend using 3m's 355 (not 100% sure on the number) 2" wide green masking tape. It is becomming easy to find now and days (Most Wal-marts have them now) This stuff is made specifically for this work. If you cannot find that, us can use aluminum foil; just make sure it is the Heavy Duty stuff. the standard stuf is too thin for it. shiny side towards the box. tape it with blue painter's tape (best to find the stuff that is rated for 14 days or more).

build a basic frame out of 1x2" lumber (or balsa if you are concerned about weight) that surrounds the spare tire area. Lay down your fiberglass mat and include the frame into the mat as you apply resin. Let this cure. Now you have the bottom half of your sub box. the wooden frame will act as your base for the top half of your enclosure and make it easier to mount and dismount it.

I hope this helps. Ganbatte ne (Good luck -or- Do your best)

I've got a tip, don't mix too much (MEKP) hardener in your resin. Ive read so many people wondering why the resin became blobby, or their work came out so brittle.

Im a fiberglass whore!!

and an important one...wear gloves! if you have install hands(cuts all over hands) and fiberglass gets on em, well it hurts to say the least. pick up a bag of rubber gloves. and wear junkie clothes..haha.

jl audio..nuff said

To build on what Bellsracer said,  you can lay down your fleece, resin that, and mabye a layer of f/g, then remove the project from your car to finish work w/o worrying about dropping resin on your car [a very bad thing]  also make sure you have some kind of mask, as working in a very enclosed area like that will either give you cancer or the munchies. btw- when do you plan on attending M.D.? I'm hoping to go in the late quarter of this year to the toronto campus.

I went to the Mobile Dynamics courses here in Toronto and I really did not think it was worth the money. For most people that had prior car audio experience it was at best a refresher course on some basics.

I learned a few things but I had 0 knowledge of car audio...any audio for that matter

I remember way back there was a thread about a FG box in a mustang. I think that thread had all the "don'ts" for FG box building that you will ever need to know. Anyone else remember that?

ROFL!!! I have those pictures still somewhere. For those who don't know, There was a guy who dumped like 60+ lbs of Bondo in his trunk and tried to shape it. LOL I'll see if I can repost them in here.
