PM sent for detailed information.

Those are still not available, still figuring out the brackets. I've done a couple design and arrived at some improvement, but I'm still not at the point where I want to be. The car is parked away from home for winter so I can't have access to a Fiero interior to improve/try new bracket design.

Thank you all for your interest, and I can't wait to finally start a production. The bracket designing is getting very redundant.

Thanks for keeping your interest!

Rob,

Agreed that sometime constructive feed back is a great way to improve a product. But lets take for example my first bracket design I've done, there was so much metal vibration because of the brackets that it was not only noticable, but it was literrally ruining the listening experiance.

Again, I am sure that some people won't notice the sound (Like if you have hearing problems, are older, don't listen to music very loud, if you listen to music that doesn't have alot of bass). If you are in that group of people, the brackets will only make a very little "buzzing" sound barely noticable. (Even though I notice it)

I have been trying that enclosure in the most extreme condition (Because trust me, I've abused it to ensure the quality of the product) I've noticed some issues:

#1 - If the enclosure isn't made properly (The fiberglass process), there will be rattling from the fiberglass;
#2 - If only one screw to mount the subwoofer in the enclosure is stripped, there will be rattling noises;
#3 - If only one screw to mount bracket to the enclosure is stripped, there will be rattling;
#4 - If there is not a good sceal because of the opening, the bracket holes or anything else, there will be distortion/rattling noise;
#5 - If the metal bracket is attached to the metal frame directly, there will be rattling (Intensity will variate depending on the volume, bass etc....);
#6 - If music is listened loud enough, the metal screw used to attach it to the frame will loosen and create MAJOR rattling;
#7 - The enclosure isn't supposed to be in contact with the dash, if not, you probably guessed it: rattling noise!

Those are all the factor needed to be considered in the design.

This summer, I will try to improve my bracket design by making a 3 contact point design (So that the enclosure can't move in the X, Y or Z axis), I will try to use lock nuts (If they fit) to keep the bracket from loosening. And if there is still some noise, I will try to come up to a design with metal and rubber brackets to lower the amout of vibrations.

The biggest reason why I'm not starting a production and everyone is supposed to making their own brackets, it's because I don't want people to judge my enclosure design by saying it is faulty and not worth the price, when the only reason it makes rattling noises, it's because of the bracket designs.

The reson I KNOW that it's not the enclosure design, it's because I already tried a couple of enclosure in a fiero, just sitting on the floor without any mounts. The sound was amasing! There weren't any unwanted noise coming out what so ever. But it wasn't practical, it was using alot of the passanger legs area and when I was making a corner, the enclosure was tumbling one side to an other. It's not something you want your subwoofer to do.

I hope you get a better understanding of the process. Right now I do have a certain plan, I just don't have the time (School has priority, sorry.) And the car to be able to work on it. If things doesn't work, I will consider (as the last option) still selling the enclosure and people will be responsible for their own bracket design. :/ But this summer, i'll be making it a priority because I am tired that this project doesn't see the sunlight.

Bump so it doesn't get lost! Summer is approching, had the chance to go in my car this weekend to listen to a couple of songs while the car was parked. Damn that sound is exquisite! Better than I remembered!

Only waiting for college to finish up and then I'm jumping into Fiero projects! (Heres a small list of things I need to do.)
-Repairing my sunroof that leaks;
-Make something to lift the back of my car;
-Finish off the engine I'm rebuilding
-Change the engine for the one I've rebuilted;
-Rebuild the tranny;
-Switch everything bushing on the car to polyeurethane;
-Install a motorsport bumpsteer kit;
-Repair my rack & pinion;
-Make an alignment;
-Changing headlights;
-And it goes on and on........ (And this is only for my Fiero)

But don't worry, I will be really pushing myself to start a production of enclosure even with all that stuff to do!

quote Originally posted by TG oreiF 8891: Glad to hear you are still working on it. It is probably too late now, but it sounds like making the enclosure a smidge smaller might give you more room to attach brackets and/or padding at contact areas to eliminate rattling noises. Still anxiously awaiting a final product.

It's true, It's kind of late. There would be ways to fix that up but it would be costy and long. It would be my last resort. We will se how thing goes, I have a lot of ideas on the sketch board and we will see where it goes.
