I decided to make a little project in my new car. Its a 00 bmw 5. Because sometimes i need the full space in trunk (for shopping )i decided to go for a removable sub/amp enclosure. When removed, only the amp stays in the trunk. The pics tell you what i'am meaning. Let start with the pics. The trunk   wooferring mounted  Adding a support for the amp  Sculpted with foam the sides for a perfect match with the contours of the trunk  Stretched fleece  This is how it is supposed to be with the amp in place  Glassing the whole thing  Applied bondo with a brush. Thinning bondo with some acetone and hardener is much more easier to apply. Hope you like and give yr comments (also negative) Next step is sanding. I will post more pics later.

Good job. What are the holes in the back for?

They were made for easy access inside the box to apply a few layers of FG mats. When its finished i will close the back with mdf and resin.

I cuted out a ribbon in a sheet of plastic and stappled it to the mdf ring.

I thinned bondo with resin and acetone and added some hardener. This was almost liquid and can easily be applied with a brush.

That looks awesome. You have skills. But how are you going to get that mdf disc out that you used to hold down the fleece on the mounting ring? Won't the resin bond to it? Can't wait to see it finished. ------------- blah blah blah blah

thank you for the compliments. About the mdf disc, look at the last picture, you 'll see !  I didn't resin on the mdf disc. It was relatively easy to take out the disc.

ChrisZ3, what ratio of bondo,acetone and hardener do you use? I've never tried it before and need an idea of quantities you used. Thanks ------------- In a world full of copycats, it's great to be an original!

Ok those last two pictures were red Xs when i looked at this earlier. But i still dont see how it didn't bond a little, but i'll take your word for it. How much resin did you use for all that? also how is that huge amp gonna mount to that tiny square?

@1hot944
I mixed an amount of bondo with some resin and a little acetone until i have an almost liquid mix. then added some hardener and mixed well again. I didn't use any ratio. It's the first time i was trying that and it came out very well. The mix is alot easier to apply with a brush and is time saving. Let cure and start sanding.

what method did you use to strengthen the enclosure???
and also are you using liquid bondo to build up and shape the enclosure???

@audiomechanic
I layed on the inside 4 layers of mat. I am also going to put some rope dipped in resin on the inside.

the rope thing is for if you are gonna add more layers......it is to give the mat and resin curves because that is where the strength comes from(curves)..... so if you are just gonna resin some rope to the outer layer, it prolly wont do much good unless more layers are added on top of the rope.

I usually use just resin to thin the bondo. If you use acetone it will make it too brittle. At least for paint purposes.

ChrisZ3, what hardner did you use for the mixture? resin or bondo? I have heard of this being done, more so with resin and acetone, not so much bondo, but have wondered if this was possible, since I am sure that is all spray bondo is. Just wasn't sure as to which chemical to mix in with it. But does look good so far. I hope to see it fully finished. I will be starting mine tomorrow, which is a complete trunk install with a false floor in a 99 Maxima. I will post pics, but please let me know about your mixture. Thanks!

kps67: It holds up great. You can add as much fiberglass resin as you want to it and get it pretty runny. That is what I do when I need to fill in small gaps, pin holes or small caveties that need a little more strength (tweeter pods) and then I use bondo hardener. If the space is to big then I use ground up FG or cotton flux to thickin up the stuff. ------------- Having Fun in Texas!

I like the idea of thinning the bondo iwth resin....The cotton flux ground up sounds like alos a good idea although ive never tried it....Very nice box by the way...post the finished product when you get the chance...Cant wait to see it
