WTB 8" Under the dash custom Subwoofer Box (Page 11/22)

As you requested, a picture of the driver side:



It's a tricky question. In theory, yes someone can still use the footrest, but the feet isn't flat on it unless you have very small feets. Here are some pictures with my feet. Note: I wear 8.5 shoes, for all the 3 pictures, I did not moved my foot, it's just different picture angles.





So this is why I'm strongly recommending this for the JL Audio:

That makes sense, I didn't expect you to. Just one SKU for the most common denominator.
I just didn't know that the space available changed depending on A/C. Didn't know '84 was different as well.

Do you think that subwoofer would fit Amida's 355 dash? That may open up the market to kit car owners as well and increase the potential customer base.

What are the physical dimensions of this box?
i.e.: what is the maximum depth of speaker this box would allow for?

Sorry for the wait, I have been planning on how to explain everything properly and, it took some time.

We did realized the 84's not the same a couple of weeks ago.

Now to answer questions:
I have never seen amida's dash in real life. Though, if the dash is bigger and has more space behind it, it should work in theory. Though there is absolutely no guarantee it will fit. The amidas dash might not fit as the same place, therefore its rounded shapes might be in the way.

OK, dimensions:
If you look at this link: http://mobile.jlaudio.com/p...ubs.php?series_id=27
Scroll down and you will see te JL Audio subwoofers dimensions. I will use it as a visual support.

-The subwoofer Overall Diameter (A) is maximum 9 inches (If not, the subwoofer will exceed the enclosure's diameter)
-The subwoofer Mounting Hole Diameter (B) is approximately 7 inches minimum. (It can be cut bigger to make the Pioneer subwoofer fit)
-The subwoofer Bolt Hole Circle (C) needs to be inside the dimensions of (A) and (B)
-The subwoofer Mounting Depth (E) is about 8 inches maximum.
Think of your subwoofer as a cylinder, 7 inches in diameter and 8 inches deep. To clear every odds shapes, count 3.5 inches down the top of that cylinder. At this point, the cylinder needs to reduce its diameter to 5 inches. Now it will alow it to go down 4.5 inches until it hits the "bottom of the box". So now imagine a cylinder of 7inch in diameter by 3.5 inches long, then an other cylinder attached by the center that is 5 inches in diameter by 4.5 inches long. this is the space aloud in the box. That's why you need to consider not only the magnet size, but the shape of the subwoofer so it will be able to fit in those two cylinders. Which makes it difficult to say if some subwoofer fits or not before trying them in.

Again, this box has been planned for the Pioneer and the JL Audio only. I did not took in consideration other subwoofers.

Note: all the dimensions were taken on a production enclosure. Though because it is fiberglass, the thickness of material may change from one enclosure to the other.

Now updates!

I have installed my first enclosure under the dash in an A/C car. I will have to re-design some of the brackets again. Make a walk-through of the mounting procedure since it is very tricky to install. The pile of work is still growing for this project since every little details seams like if it makes a difference.

How goes the project... don't want it to get lost in the achives before it comes to pass... Got to sawp my indys cracked dash for a new one at some point, so this might be the perfect thing when the time comes.

Just to make things clear, I have no intention on letting go the project!

Hi everyone!

I've just finished my semester in college, and the second one will start un the begining of January. So I haven't had the chance of going through this.

As for production and having some ready for christmas gifts, well, it's christmass in 2 days. The other problem I'm running into is that it's winter. Therefore making fiberglass in a garage closed, without any ventilation because we are heating the garage, hasn't the best smell and the best effect on a human body. The chemicals are so strong it can affect negatively the human body if there is not enough ventilation. I might still work on the design though (Ex: for brackets).

Though don't worry, the project is still alive!

I wish you guys/girls a happy holidays, happiness, wealth, great health to you, familly and friends.

Thank you, you too.

Living in California, I sometimes forget there is a thing such as "seasons".

Black Pegasus DEC 27, 01:37 PM
It's ok, :P

We have the great advantage of having a white christmas, but the inconveniant of not being able to drive the Fiero all year long. :P

Personnally, I would preffer the warmth and the car, over the snowy winter... lol
