And finaly done, We set up the Donor car with JL AUDIO XD600/1 Amplifier. This amplifier is smaller then the HD sries amps, We were comfortably able to install it under the pass seat. We also wanted to try out the 13tw5 Slim sub, Biy are we glad we did..... AMAZING BASS responce, even though we only added the sub and amo to the factory stereo we were pretty amazed with the amount of bass and how low this sub was able to play, yet it was very fast and hard hitting...

Here is spme pictures, we chose to show the subwoofer, and will be sending out a carpet sample to get peferated and have it be available for those looking to finish the trunk with a detailed and finished look.

For those who want to conseal the whiole sub you can by using the black styrofoam piece that comes in the trunk and lay on top of the box and lay your carpet over it. I personaly like seeing the sub, but you certainly can cover it.

One other option is to place the carpet on top of the e\mpty enclosure, Mark the whole, cut center and screw the sub in with the carpet in between the suband box, which will give it a nice finished look as well. if you were to take the box out carpet will be attached top the box and sub.

We carpeted the bottom of the enclosure for a snug fit in to the spare. What you will need to do is unblot the spare tire nut, Position the magic box in place, carefully lift the sub box back out and tighten up the nut without moving the spare. Then simply just drop the box back in.

Pictures shown with a 13tw5, we still have the 10" slim sub option available...

Are theese avail for sale ? when and how much ?

JL Audio has a complete system coming
 

Saw on the JL Audio page that they have a sub enclosure coming for the 2009+ 370Z coming soon.
Ain't gonna be cheap. The older models is available already and it was 1000.00+ but comes with two subs.

If you choose to fallow up on this box here is the new thread
http://www.the370z.com/audio-video/1...tml#post439816

^^ What’s the plan for the 370Z Roadster? Any ideas for woofer location/enclosures?

This might fit, Anyone have a roadster they can stop by the shop?

Mecha, how does your sub sound in the ~.3 cubic ft enclosure? I had a fiberglass box that was roughly ~.7 cubic ft in another car and the roll off was terrible with a 12" MB Quart sub (i.e. it would try to hit low bass notes and was just silent). There was literally a night and day difference between the sub in a 1.1' box and the .7.

The sub sounded excellent. More than enough bass for the car. I no longer own my Z, i sold it and i bought an IS-F (needed a 4-seater).

The box and cover are now for sale $75 for both. The speaker is for sale on ebay for $70. PM is interested. Pickup only on the cover.

Sorry for the late reply.

Still for sale. $25 pickup only.

Another DIY 10" subwoofer in spare tire
 

Hi Everyone,

Sorry to tag onto an almost 1-year old thread, but thought it would be better to keep this information together rather than starting another.

I was inspired by the several examples that members have shared and wanted to contribute another example for those who might want to take a stab at making their own stealth sub box that fits inside of the spare tire. I have a '10 base+sport so I believe the spare is a little larger inside to clear the brakes vs the non-sports.

I used the Pioneer TS-SW251 10", 4ohm shallow mount sub and a Rockford Fosgate Punch 500-1bd. The sub is speced at needing 0.35ft^3 to 0.70ft^3 for a sealed box enclosure. Based on the inner diameter of the MDF pieces I used I was expecting 0.46ft^3. Going by how many packing peanuts I could get in the enclosure at the end I probably only ended up getting 0.42ft^3. I am not sure that I could do much better than this as I feel like I really sculpted the rings to take up every bit of free space. The rings are only about 1/2" to 5/8" wide - outside diameter minus inside diameter - (I think people like to use 3/4" thick MDF for square boxes) but being circular and braced against the metal of the spare rim I decided to take a chance. I used 6x 3/4" thick rings and 1/2" thick pieces for the top and bottom. All these pieces were glued and screwed together. I also threw in some polyfil on the inside to help the enclosure act a little bigger.

The top of the speaker is just a little taller than the styrofoam spacer that goes around the spare. Once you put the plastic shelf/sheet thing and the trunk carpet over the sub you can't tell it is there from the outside looking in. I may come back and try to protect the speaker some more, but I feel like it will be fine with light stuff in the back like groceries, which is all that ever goes in the truck these days.

The speaker still needs to break in, but the sub seems to put out a decent amount of bass. It won't win any SPL awards or wake the neighbours from a block away, but it fills out the car and the stereo well enough. I got the bass boost control knob and mounted it where the heated seat switches are on the touring models. This lets me increase the gain on the bass easily when I want more for a particular song.

Thanks for taking a look. Enjoy the pictures.

Good Job,, !!!!! Looks great !!!

^ Great job, perfect utilization of the space! :tup:

John

im bringing back this old thread since im really interested in taking a stab at building a spare tire box. I dont think i want to spend the $400 for a fiberglass enclosure and this seems like the perfect alternative.

A DIY on making one of these would be great! but i have yet to find one.

Instead of a 10" shallow sub, i was considering a 8" sub, maybe ID or Polk MM series. Does anyone have reccommendations as to a sub to use?

I listen to both rock and rap, and i do like the deep bottom end a larger sub creates but its not a necessity and i dont want to beat down the block and rattle my car apart.

do a 10". it wont be too much. The box is easy to make, cut a bunch of rings glue and nail them together, done.

i wonder if the mm 10" would fit?

Polk Audio - Car & Marine Audio Speakers

Looks awesome, did this fit on top of the spare tire? How much did you say the material (w/o sub) cost you? How long did it take? If you put, let's say a case of water on top would it damage the speaker? Thanks

Not enough air space.

What about, this is my next idea, taking out one of the foam pecies beside the tire and building a box there in the same basic shape, you can get .7 ft on the drivers side for sure, it would fit under the floor and no loss of hatch space, put the jack in a bag inside the spare tire.

I'm going to be doing a 10 on either side when i get time again.

i like that idea too. Whatever is the easiest and concealable is what im after. Ill have to take a look at that as soon as my car is out of the shop.

hmmm, pioneer shallow 10" or Kenwood shallow 10"?

MTX shallow 10? puts out cleaner and more then both of those, TT6510's are what i'm running in both of my Nissans.

Wow, that's great!

ill have to look into the MTX. This might be a dumb question, but wull i get more low end from a ID8 than from a 10" pioneer shallow sub?

no, but it would be cleaner.

Hi hdskull,

It fit in/on the spare tire. It essentially takes up the space inside the rim and sticks up above the tire the height of the styrofoam shelf.

3/4" MDF is $32 (used most of the 4'x8' sheet after a couple mess ups)
1/2" MDF was left over, but $25 for a full sheet (only need half a sheet)
Black paint was left over, ~$3 for a can of spray paint
Liquid nails is $2.50
Screws ~$2
Polyfill ~$5

I have a router table that made it pretty easy once I made a circle cutting jig (just a piece of wood with a dowel in it that I would spin a square piece of the MDF on to make a circle). I cut out a circle to the correct outer diameter, offset the jig by the thickness I wanted the ring, and then cut out the centre of the ring. Cutting the pieces probably took 4-5 hours, with all the setup and redoing a couple of rings I messed up. Letting the glue dry and paint dry took several days. Took me over a week because I just worked at it a little each day.

The Pioneer speaker is pretty tough. It's not like it has a deep cloth cone or anything - it actually has a hard plastic plate on the top, plus there is a raised ring around the speaker. I put groceries on it all the time and don't feel like it is getting damages.

Good luck if you make your own.
