If you can do it to the specs that the sub needs, then more power to you. Most, if not all of the JL Stealthbox's are made from fiberglass custom molded to fit wherever they choose to install the stealthbox. They know the best way to design the enclosure so you get the maximum benefit of the sub.

Not knocking on you, I just rather have a well known and respected audio company to make the Stealthbox for me since they have all the technical know-how. I would do a custom fiberglass box as a 2nd resort, and the Z enclosures as a last resort.

Months ago, April I believe, a member here made a fiberglass enclosure that sits down inside the spare. There is a shop in Atlanta that used to post here, that did the internal volume and ran the numbers for such an enclosure, was around .6 cu ft. There are a few thinline/slimline subs that will work in that size enclosure............ and you don't loose use of the spare.

JL also makes a sub that goes into the spare tire for the Mazda 3. If they could do that it would be perfect. You do lose a little bit of dept but to me that's stealth. It would look completely stock.

I have a stealth box in my car, made by my friends dad, with two 6.5" kickers. I painted it black to match the foam. Those are subwoofers by the way.

Nice, now that's what I'm talking about.... it sits down in the spare correct?
This can also be done with one 10" thinline sub. How do the 2 6"s sound?

John

Yes, it sits in the spare tire. You can put one shallow 8" or one 10" sub. The two 6.5" complement the speakers I put up front, it's not loud like two 10s you know, but sounds perfect inside the 370z.

Cool. Is the cabinet fiberglass? I assume the part we can't see that sits in the spare is round. Approximately how low do your two 6" go? I'm a rock, jazz, and blues guy, so 30hz or so would be sufficient for me.

John

lol

No, it's wood and yes, it's round and the subs sit flush with the top. The subs are about 2-3/4" deep. The guy who made it is a carpenter and he is really good with wood.

You might have a market for these, think he wants to make and sell any more lol How low do you think it goes BTW?

John

Jowe, how does putting the carpet down effect sound quality. I know that at sub frequency ranges it shouldn't make a huge difference but I am just curious if there is anything weird that goes on. I was looking at a memphis shallow mount 10 for this area and since you have paved the way any insight into issues would be great.

It doesn't make any difference with or without the carpet, at least with those subs.

Yes for the Stealth Enclosure!
 

I would spend the cash if one is done corrrectly.
