370Z Sub Box Feeler
 

I am creating a mold for a fiberglass sub box that would be replace the foam piece located in front of the space tire in the rear hatch area of a 370Z.

The sub box would include space for a small amp and 2-3 6.5" subs or 1-2 8" subs. The existing foam piece (see attached pic) would be removed and replaced (drop-in) with this sub box. The height would vary depending upon the sub size. The height could flush with the rear hatch floor for 6.5" subs; otherwise, will have to extend up above the floor a couple of inches to clear a 8" sub.

This is an initial feeler to gauge interest. I will give interior specs to properly size your sub's XMAS and other sub spec requirements later. PM back if interested.

i've thought about doing 3 or 4 8" in that spot, sounds like a good idea, maybe look at a vented box maybe?

Fiberglass is always nice!

hmmm.... im interested. Im looking to do an upgrade around the first of the year.

i was thinking about making a mdf box to fit int he spare tire with either an 8 or shallow 10. i wonder if you could fit 2 8" jlw3s?

I would get with someone that does custom fabrications like that, and have them do measurements.:tup:

8" sub will not fit flush with the hatch floor. This area is only 7" wide and 7" deep. If you raise the sub box above the hatch floor a couple of inches or less, then you can install a 8" sub.

JL Audio 6W3v3 will fit with no problem flush with the hatch floor.

There are some 8 inch woofers that you could fit depending on their air volume required and their mounting depth.

8" subs
 

I curious on what 8" subs you are refering to that will fit into a 7" wide space.

I'd be interested if the price is right. Personally I would like to see the box rise above the rear floor board (maybe to the height of the bar back there). It would be nice to get the box painted to match exterior etc. and to show off the craftsmanship.

Interested in seeing the final product, I like the idea so far though!

:iagree::tup:

Me too, get 'r dun.:tup:

Sub Box Feeler Update
 

So, based upon the responds, I will send back a few design concepts of the initial sub box. The idea is to remove the foam piece located in the rear hatch area and replace it with a sub box. The sub box would be designed to accomodate 8" diameter subs; the largest sub being a JS Audio 8w7-3 8" sub. I will email the initial interior volume (cu.ft.) to gauge the necessary enclosure space specifications.

Sweet man, Im looking forward to seeing the finished product:tup:

Sub Box Initial Concept
 

Me do! The final design will likely be after the christmas holiday. I will post preliminary design ASAP.

Cant wait bro!

Sounds very interesting

Theres a few of us waiting to see this.

Composite Fiberglass Sub Box
 

Post up your top sub box trim ideas.

I am thinking of black speaker cloth over the sub area and black matt material over the dead corner spaces. An access panel in similar black trim over a amp area. I may consider smoke color lexan with a Z emblem cover plate housing the amp area.

this sounds like a nice setup..

Sub Box Options
 

Too early on the price it all depends upon the price of the materials and my time. I am not that interested in making money on it, just making a sub box that fellow 370Z owners could use without removing the space tire,etc.

Materials alone are expensive.

affordable is nice

I know the horrors of fiberglass, the labor and time is intensive and the cost is high.. but once the project is done, its usually very very nice!

In my experience constructing RFP boats, a sub box is easy... no stress points to be really concern about. Of course, the key to a good sub box is the hertz level it is design to. Yes, the cost is more that a MDF sub box just for the material.

I have not been impressed with the manufacturing of the typical fiberglass constructed sub boxes. This is something I enjoy doing.

Dude, I love fiberglass work, it just kept adding up... before I knew it, I was hundreds of dollars in materials, and paint/ air brushing/ clear... just pricey!

Speaker Grill Cloth Source
 

I am looking for a source of speaker grill cloth to cover my sub woofer and amp/signal processor rack.

Also, looking for a source of binding posts. The local Radio Shack does not stock the screw down type.

The sub box is in its early stage of construction. Once it is finish I will post pics. My set-up is with one 8" sub woofer located on the driver's side and the amp and signal processor located on the passenger side.

Additional sub woofers could be accomodated at the expense of location the amp elsewhere.

:tiphat:

Seems like you guys are going thru allot of trouble for a 8in sub,when you can fiberglass the inside the spare tire and put 6,8,10,12,13.5 sub plenty of room back there and you can keep it flush so you don't lose any space.:tiphat:

Thats for the tip...I'll check it out!:tup:

Sub box
 

Yep, I am designing an alternative the the space tire sub box which is no trouble for me. The idea is to have the amp and small sub located out of the way that would not have to be removed in case of a flat tire on the side of a highway under the worst scenario!

Alternatively, I would remove the space tire,jack,foam pieces and construct a false floor that could allow for large sub(s) and amps, but in do not see the need for it in the 370Z (seems to be overkill to me).

37Z, thanks for taking the time to do this. I'll be very interested to see what you come up with. Roughly how much room do you have left on the passenger side for your amp? I'm wondering if I'll be able to fit an amp and, possibly, MS-8 in there or not.

Thanks again!!

Interested...I'm thinking about a couple of 6's in that space...

Two 6" subs should fit without any problem. What brand? Let me know if you want to include a amp and/or signal processor in this space.

I have only one 8" sub (Alpine SWR 843D) sub located on the driver's side with a signal processor (Audison bitTen) and HERTZ HDP-5 amp located in the passenger side. I have been sick and have halted constructing the sub box at this time. I will post pics once the sub/amp rack is completed.

Probably JL W3's. Haven't decided on an amp yet but I think from a ventilation perspective it would be better under the passenger seat. I don't want the subs to be visible once installed so the carpet would also cover the amp if installed in the same space...

I believe JL Audio's 6W3v3 are 6.5" diameter. I almost went with 2 of these instead of ALpine's newly redesigned 8" sub. Two of these JL sub's with a small amp would fit in these space. What amp are you contemplating?

I'm definitely interested in seeing the results of your subwoofer box. I also think running two JL Audio 6W3v3 would be interesting.
