Thought of sub enclosure - opinions

[CasopoliS]

Attached is a picture I drew up of a custom sub enclosure. It consists of PVC pipe, with stainless steel plates on either end. Teh sub would mount to one of these plates. There is an o-ring (or other method of seal) between the plates and PVC. The plates are held to the PVC (and o-ring) by "pinching" them together with steel rods (bolted evenly on each end). The picture should show this well. I am going to do a 3-D drawing as well in IDEAS. The PVC would be painted the color of my car. The stainless steel plate behind the sub could actually be plexiglass so you can see the magnet. These plates would be laser-cut. This could bolt to the floor, or upside-down where the current system is. I could also fiberglass this PVC to "mold" it to the truck ceiling, and have it kinda hang. This was an old idea of mine, that would make a sealed box very well. Terminals would be mounted on the plate or PVC somwhere. The internal volume would be easy to find (pi*r^2*h). Where h is the length of the PVC and r is the PVC's ID/2. Let me know what you think. Cutting the PVC perfectly straight would be key, and making an o-ring groove in the PVC would be time-consuming.....but nonetheless...it can be done. Custom amp rack would be made as well.

I figured I could position the sub enclosure in different directions, to see what sounds best....then determine how I wish to mount it. Does the system sound better if the sub is facing the inside of the car, or the back of the trunk in the MSP? My old systems sounded better facing back, as the sound reverberated off the trunk lid and back into the car.

Thanks for reading....your opinions would be greatly appreciated.

Oh yea....it will be an Alpine 10". Either type S or Type R. Probably R with mono amp.

Looks pretty cool, shouldmake for a different kinda industrial sorta look. I think I've actually seen something similar done before, but I just can't recall where. As far as the seal, I'd use Silicone caulking it would likely do a better job of filling everything in, not to mention be WAY easier to deal with. Functionally as long as you've got some thickass PVC I don't really see much of a problem. Just a matter of getting the seal to be strong. You might also want to atleast put some refrence screws into the pvc itself through the plates if possible, just to keep them from "walking around" as you tighten your tension bolts.

yeah, very interesting. the design seems pretty good to me. cuts would definately have to be very precise and straight, but i think it should work very well. sealing it would be kinda interesting. i wouldnt go with an o ring, but maybe some weatherstripping, or as poseur mentioned, silicone. or maybe even both. but this is definately an interesting idea. id like to see how it turns out.

Thanks, yea we will see. I still do not know what I am going to do. I might not even built it like that. Question -- How well is the factory plastic enclosure bolted to the ceiling of the trunk? I could chop that up a bit, keeping the bolt locations, and just re-fiberglass it to hold a 10" either facing the trunk or the driver. It will just hang much lower, but still be bolt-on when I'm done. Anyway.....is the plastic solid enough to hold the weight of a 10? Will this rattle a lot? Thanks. I think I am going to search around for sub placement to see where people are putting them.

I saw this for sale early this a.m. It is for a 12" though.
