Issue with Subthump stealth box in T/A??
I just received a driver's side stealth box from subthump. I tried installing it, and understand its suppose to be a tight fit, but I can't get it back far enough to mount the plastic trim piece over the top of it. Also, the way it sits now, I wouldnt be able to put the t-top in without the sub rubbing it.
Anyone else have issues using their stealth box?
My previous set-up was with their amp rack (which I am reusing) and the rear deck box...and didn't have any issues with fitment.

Here are some pics.




The front part of the box is pretty close to where it needs to be, but the part against the back wall sticks out towards the passenger side too much (where I can't get the trim piece on). The car has never been in an accident and there is nothing behind the box...its rubbing hard against the backwall of the trunk space though.

1. the back corner hits the corner screw of the taillight
2. the angle on the lower right corner of the box (when facing it) is not quite the same as the angle of the opening.
While I could leave it like in the pics above and have my t-top rub with the sub installed...I am not very satisfied with the fitment. Maybe I got a bad one, but I am going to call them back and see if I can get a refund.
That being said, just found through searching that Kee audio also has a box available...anyone have any fitment issues with their box?

If you had a cd changer, there is a stud & a bracket that have
to be removed in order for the box to set flat.

I made a template and measurements and have been emailing subthump. They said they were willing to make modifications for my fitment. So hopefully everything will be settled.
I will post updates and hopefully pics of the modified box when I receive it.

From pics I have seen from other ppl and from what I have been told by others, their fitment is the same as mine listed at the top unless they modified stuff. But most of the pics I have seen, upon close inspection, the plastic trim doesn't fit properly ontop of the box.
Supthump told me the box design was molded from a camaro.
I talked with Kee audio as well has having heard from other people. The Firebirds/TAs have a shallower cubby hole than Camaros. If a box fits a Firebird (Kee audio's design), then it will fit a Camaro with no issues, but the same is NOT true the other way around.
Subthump has already told me their box was designed from a Camaro, so that is why it is not fitting properly.
Subthump agreed to make some modifications (but I do not think he believes me that pontiacs have a different sized space), I will receive the box tomorrow, hopefully it fits up this time.
The Vantage stealth enclosures were made by JL Audio and are no longer produced. They fit perfectly and sound great...I was suprised that a plastic enclosure sounded that good with less density then mdf. I still have 2 of them I kept around just because they are not made anymore. They also have a ton of depth for large motor structured subs.
The enclosures I have fit with no issues at all but do have slightly less depth then Subthump box. I do have one other type of mdf enclosure I use that is coated like the other one I have but has enough depth to fit a Kappa Perfect 10 which is a fairly deep sub. Both of my mdf enclosures are coated with a truck bed type coating that seals, protects and offers a deadening type effect as well.
Anyways, just wanted to say Steve was a stand-up guy and willing to work things out. Here are some pics of the final install. I already had the all silver amp and cap mounted from the previous set-up and did not feel like trying to rearrange everything when I added the 2nd amp this week as well.
