Just in case you thought about it.....

OK, I couldn't stand not knowing....so I tried my first fiberglass project. Unfortunately, the tolerances in the area are WAY too tight to make this work....Oh well, good excuse for a few cold ones on a Saturday afternoon.

Here are some pics of my failed experiment:

layer of glass. I have to say, with one layer of glass, this thing was very strong. I traced out the shape of the OEM enclosure on to some 3/4" MDF. Then I was going to add one or two more layers of glass on the inside of the mold and then attach it to the MDF face plate.

BUt, after letting this set up for a few hours, I spent the next hour try to get the OEM enclosure out of the shell. I finally got it out, did a test fit, and the fiberglass enclosure was way too large. I guess the only way to possibly make this work is to use this form as a negative mold and then make successively smaller forms.....way too much work for me.....who needs cargo space anyway. Time for some MDF and a W7:D

thanks for sharing...i thought about doing a similar enclosure out of fiberglass like yours, but haven't attempted it yet..keep posting as to your progress...thanks
 
Have you given any thought at the type of box I have? I will be creating another box for my wife's Runner in the next few months. I think I will shrink her box a tad, so that she has room for the outlit. If you would like I will re-take the measurements of my box and post it, if you are intrested in re-creating it.

That would be great if you could pass along the measurements. This is plan B for me....maybe with a twist. I was thinking about removing the cover for the cargo area behind the box to get some extra depth...then mount my amp in there as well....Picture your box but extended into the existing JBL box space. My only problem is that on the JBL model, the cover is secured permanently....but could be removed with some delicate mods. So bottom line, I need to kinda destroy a panel to do it....I'm gonna call the dealer today to see how much the panel costs before moving forward. Based upon the depth, I think I could fit a JL 8 and a 300/4 in an enclosure....if I got real crafty, I might be able to fit a 10 and also not have to worry about depth issues.

Did you remove/modify the cover to the panel area? What sub are you using and do you know the mounting depth.

How did it get so much bigger than the spot? How did you make that original mold that you started glassing?

I've been wanting to try this as well, just haven't learned how to work with glass yet.

The first layer is thick tinfoil around the enclosure for protection...glass won't stick to it. The next layer is an old t-shirt for the first layer. I applied a layer of resin to the shirt....this acts as a basic form to apply glass to....but does not really add any strength to the mold. Then I added a layer of glass matting and resin to the entire mold. So by time you have the tinfoil, t-shirt, resin, glass, more resin.....it gets thick quick. I think if I tried to just do the t-shirt mold and then remove the OEM enclosure, it probably would not have held its form. Make sense?

BTW, then entire project was only about $25.
 
did anyone find out how much the rear panel would cost?...because i'm thinking of modifying one like the non jbl system rear panel...4runners with the non-jbl system actually have a little pocket which can open and close in the place of the jbl amp and sub. it may be a good place to place an amp or modify it for a sub enclosure.

I'm supposed to get a call back today on the parts.
 
If you had glassed "in" from the foil instead of out, it would've fit...correct? How much room is actually in there for a sub? How deep of a sup could you fit?

Inside the foil is the OEM enclosure. I don't think the tinfoil will hold form to glass against.

I think I could of managed a JL 8w3v2...about 4-1/2" mounting depth.
 
Sorry about the late response, I am away on company business. I will get those measurements and post them when I return, which may not be untill next week.

Local dealer prices

Entire trim panel: $365
Pocket door: $85 if you wanted it
Tray inside the pocket: didn't price

Ouch!
