OMG that is some crazy fiberglass work you got going there. Great job documenting your work with the pictures but how did you manage to take pics with all that fiberglass glued to your fingers? hahaha

I'm still not sure what you are trying to do since if you are just using the volume within those roll hopes, it can't be enough volume there for a subwoofer can it? Are you planning on using this more for midbass?

That's a lot of work if you ask me to do something that the S-pods already do without all the hassle.

If you are trying to create sub-bass, there is NO WAY you have enough volume there especially judging from that pic of your speaker magnet taking up almost all the internal volume.

I've done various fiberglass projects but never as involved as what you are doing. You really do have balls to do it inside the car and you didn't even remove the SEATS!

Kudos to doing something new but I still don't see the point.....enlighten me

I'm doing a custom fiberglass box in the driver's side corner of my trunk to house a single 10w6v2 and that thing hits SUPER HARD. Just not seeing the goals of your project...

btw that girl looks dangerous with that saw....haha

That sub only requires 0.15 ft^3 and I am pretty sure it would work with almost next to nothing. I would be more concerned with the rattling that will be present when that plastic cover starts loosening up from the vibration of the sub.

I would probably have gone a different route: Make a mold of the inside and back side of the roll hoop, pull it out and glass it closed on the front side. Then glass in an MDF trim ring, shape it, clean it up and paint it. Then us a cover of sorts on the front side to keep it tightly in place (couple of bolts or screws) and mount the sub.

Then you would at a minimum know it was sealed.

Quick pic I pb'd

 

I totally agree with you William

 

S4play: Well I

 

If you really want this to work you're going to need to cut the roll hoops in the middle.

 

Pretty sure the roll hoops are symetrical on both driver and passenger sides - so you only have to make one plug and make a mold from it.

Option A:

There are a number of ways to make the plug and mold.

If I were doing this I would probably get a cube of medium to high density foam (go to a JoAnne or similar arts and craft store) and start carving/shaping until it was cut down so that it fit snugly inside the roll hoop and maximized the volume. Essentially you would want to shape the foam so that it looked similar to the gray part of the image I posted. Then I would use a body filler to smooth it all out to a nice finish. This is your plug.

Then I would apply mold release and glass over the plug to make my mold.

You then cover it with mold release and lay up your two pieces (one at a time). If you do not have mold release or a good smooth finish on the plug or mold - you could just wrap it with aluminum foil. It will stick to the part, but allow you to seperate the part from the mold.

Assuming your parts look something like the gray part of the image once you trim/clean them up - sit the parts on the MDF and trace the outline. First cut the mounting hole for the subs, then cut out the pieces that you traced. At this point you will need to probably grind away on the MDF pieces to get them to fit into the fiberglass part. you will also want to shape them with a nice round edge on the exposed side of the face. Now you have to glass the MDF to the fiberglass shell.

All that is left is grinding and filling until you get a nice presentable and paintable surface where the enclosure will be visible.

My guess is you will need to make 3 or 4 before you get a couple just right. But in the end you will have something unique, gained some good knowledge/experience and have the satisfaction knowing you did it.

Option B:

Or just PM Darknight1999 and he will tell you where to mail the check

 

Your so funny William.... lol...

As it turns out... I will and can make them for you if you get sick of sticky figures

 

:iagree, either that or remove part of the roll hoop (rear part) and make your own molding . You could design it so that you have plenty of room or volume for those subs to pound, plan Z ...

 

looking good...

 

Thank you for explaining that process Will. I'm going to check out a local store - Michaels to see if they have some foam. Your plan is the only one I can actually 'see' getting to work. I think out of all the solutions it's the most rational too. I won
