Subwoofer in stock location
 
5 Attachment(s)
I wanted to upgrade my the audio in my 03 track edition while keeping a nice clean stock appearance. I read on many sites that the stock sub location didn't work well and sounded awful, but I thought it would be worth while to try myself. I added some pictures of the box design i settled on.

I started by applying Dynomat to the entire inside of the sub location

Before building the box, I drew up an idea in Sketchup to get measurements and angles that needed to be cut out.

Before installing the sub, I tore apart an old pillow and used to stuffing inside the speaker box to disrupt sound waves making the sub feel as though the enclosure was larger.

After everything was installed, I was extremely pleased with the sound quality. I ran a 4 channel JL amp to my components up front and bridged the last two channels to the sub, giving me the all around great sound quality i was looking for in my car.

FliPPER_Z 01-23-2010 10:01 PM

asteffy 01-23-2010 10:05 PM

Yeah I can take a few more and post them up tomorrow sometime.

FliPPER_Z 01-23-2010 10:06 PM

Im guessin the speaker is facing up , and not towards the drivers seat right?

Yeah the sub had to face up. This seemed to be the only way i could make something work that was close to spec for what the JL 10w3 needed.

Attachment 426558

Ive since painted the box black so you don't see it through the grill like this picture.
Attachment 426559

Mounted the JL 4 channel in the glove box aera.

Really great box! Since it's a DIY, could you please post the dimensions? I want to make a box for my 10" Alpine Type-R. Since the sub is pointed up, is there a big difference in the quality of the sound vs the sub pointing the seat?

nelson83099 03-01-2010 03:14 PM

Next week I'm doing the same exact thing with my Z can't wait. how does it sound ?

LuciaPwNs 03-26-2010 08:18 AM

Do you think you can fit a 12" type r in there?

I don't know about a 12". but i just put 10" Type R in and it sounds pretty good.

nelson83099 03-27-2010 08:59 PM

Now if you just paint the front face of the enclosure black, you won't even notice anything is changed behind the speaker grille. Looks like a pretty cool idea. I've always wished that the Z could have a filled in bottom end without adding a visible enclosure.

Alright here are a few dimensions of the box i used. It fit real easy into this spot and could've been a tad bigger. I really doubt a 12" could be made to fit but maybe.

Thanks! i will make it fit haha

Were all those angles needed?
Main obstacle is the bracket in the back reducing the available depth.

I tried this way first but didn't like the sound with the sub facing up inside that compartment. Spent some time making a box that would have the sub on the outside. Unfortunately it was not possible to make it fit behind the original panel. The sound is much tighter and more musical with this setup.

I'm also working on a fiberglass enclosure that will fit behind the panel and the sub facing the seat, work in progress. I have the first design but it needs some more work. All of us that tried this know that the magnet will hit the bottom of the box so I will have to make some changes to make it fit properly.
