Most of the equipment is a little older but hopefully it will work for me. So far I have run all the wires for the amp and speakers in the car. Just in the finishing stages of building a custom sub box. I like the understrut sub boxes as it leaves some space in the trunk but always thought the subs were a bit too close together and I wanted something slightly different. I made the opening at the front slightly larger to better space out the subs, and I also angled the front a bit so the top will be recessed under the strut bar by 3" with the bottom flush.

I will update as things get done.

 

Looks good so far, gratz

 

sub box and amp rack installed.

 

looks good man keep up the good work.

 

Nice work!

 

Wow.. Old is correct. I Sold my Xtant 3300x on e-bay because I would not fit in the OEM Sub location. I ended up with a JL 5x500.
I sure hated to sale the Xtant.

Looking real good. Nice Job on the Sub Box.

Here is My Amp Mount:

 

Nice amp rack, looks clean!

I can't complain as the amp along with all the wiring, subs, head unit and eq were free. Just need to buy a set of components for the front. With the box, amp rack and instalation kit and harness I am only into this for about $75. Sounds pretty good for $75

 

WoW.. Sounds like a Win win for you. It looks good

 

wow..

thats an awesome box.

 

Lookin good...

 

I wasn't really happy with the sound of the subs so I rebuilt the box a bit closer to the recommended volume. I increased it from about 0.480 ft^3 per sub to about 0.67ft^3 per sub. This took out most of the angle of the front but should still look good, like any other under strut box but with the subs further apart. I will update the pics when it is carpeted.

 

im about to just build a completely new box... ill sell the old one on here or something

 

Not sure what this has to do with my thread?

 

I have 2 of the same subs that I want to reuse in the Z. Only problem is that they are 12's. If I ever get time, Im planning a custom box using 1-12".

 

The subs don't sound too bad, not the best though. I am running 2 10W3's. Would like to see what you end up doing with the 12. Any thoughts on where you will put it?

 

What I have in mind is making a box in front of the strut towers and position the sub exactly where you have your amp mounted. Time is what is stopping the build right now. That and I don't know how it would sound firing towards the front of the car.

 

Are the subs using a common enclosure, or do you have them divided into two separates?

You might want to take a look at this to get closer to your desired volume.

Also if they're the original 10w3's, they weren't that great of subs to begin with, so even running two of them, you're probably not going to get the quality that you're expecting....if they're the older model that is.

EDIT: From looking at the picture of the bare back of the box, it looks like you used a divider.

 

I actually rebuilt the entire box to get almost the exact size recommended for the subs roughly 0.67ft^3 per sub. The 2 chambers are divided and these are not the origional version subs. I later found out that most of the issue was due to setting on the amp (it is too adjustable) I lost a bit of the angled recessed look after I rebuilt it but it sounds much better.
