How do you secure a fiberglass enclosure in the trunk?

I'm doing my own fiberglass enclosure on the side of my trunk to hold my 10" RSd10.My question is how will the mold stay in there once it's complete?

its kind hard to explain....

on technique that can work if there is no where to put a screw into is to use a scrap piece of wood and resin it into the inside of your box. (making sure to seal of the sides of the peice of wood) drill a whole through it (which will also go through your fiberglass) big enough to thread a bolt through ( you will want it to go all the way through and go through the trunk carpet behind it also

next, fit a bolt with a low profile or rounded head and with a washer though the back of the carpet, so the washer will stop the bolt from going all the way through.

now thread the bolt through the whole you made in to the box. you can then use a nut to secure it in place.

you can even do this in 2 or 3 spots to spread out the load.

this doesn't work in ever car, but its an idea

if all else fails a little duct tape will hold it in place..

Mine is held on with weight and friction. All the surrounding panels hold it in place.

I read one guy using high strength velcro in three different on the back side of the enclosure.

Actually with mine we just molded two plastic clips into the box that mated with factory points for the clips. They were originally just there to hold the carpet liner along the side wall of the trunk in place but we used them to mount the box. Worked really well but getting them lined up was a PITA.

Now that sounds like a winna Solice.

yes if u actually plan ahead some cars have metal faces behind that carpet that the carpet clips go into..

so what i done in the past is actually thread a bolt through the hole and then secure it with a nut on front. you will fine usually two or more holes so maximize it.

then depending on how u are gonna make the back of box..ie if all resin then simply take a piece of wood mabye 3 inches by 3 inches and drill hole in middle and counter sink the back of hole so the nut u used to secure the bolt will sit in the wood so use 3/4 inch thick piece.

now secure the front of wood with washer and nut..
tape up front of that piece so to protect nut and washer.

then lay your glass mold and resin in those pieces...when all said and done remove..

keep in mind to plan that u will need to secure this enclosure after the ring and front of box is done so make sure to u can reach inside and tightned the nut when u stick it back on the studs..

it works verywell because u arnt making new holes and the enclosure is secured to car.

hope this helps..

wood at the base and screw through with m8 bolt through the floor with big washers to spead the load at least m8 size

i dont want mine moving if i have a crash (survive the crash only to be crushed by a sub box)

I epoxyed and resined a metal brace for mine at the top, and then put a bolt through the bottom.

I'll see what i can attach the mold to.One more question.I've see two different types of sub fiberglass enclosure faces.One with just a mdf ring with fleece stretched over it then resined and the other with and entire mdf face with the rest of the eenclosure fiberglass.Is their an advantage to one over the other?
