I need to add some boom to my truck. I already have 2 Kicker 12" CVR's which have a mounting depth of 6-5/16" and are calling for a minimum of 1 cubic foot of air space in a sealed box. I found a prefab box but it is not deep enough to fit the subs. I am trying to make a custom box to fit in the tray behind the seat and I think I have figured it out but the box does not have enough air space. I am going to add some polyfil which tricks the subs into thinking there is more airspace than there really is. I was just wondering if anyone else has solved this problem. I use my truck as a truck so no ideas like pass throughs or the armrest box. What have you done and pics would be helpful. Thanks.

 

Your best bet is to go to a good stereo shop and have them custom mold a fiberglass box against the back of your cab. And you might have to slide your seat forward a bit too.

 

The best way to get the desired air space in a regular cab is to remove the tray, and build a box that sits on the floor.

Here's a link to what mine is kinda going to look like.

Hemi44, I have seen that box (the only prefab for a dodge regular cab) but the problem with that is it doesn't have the right mounting depth. I was thinking about a shop doing a custom fab fiberglass box but then its alot more expensive than buying a sheet of 3/4" MDF and its far more rewarding to make your own box. Since I am going off to college in the fall, I also wanted to keep as much space in the cab as I can. I am being really picky becuase I do want to keep the tray in and as much space as I can. I also want it to look custom but not be obvious when you look in my window in a parking lot. I think I have figured it out though. I should be making the box toninght or tomorrow and when I finish I will put up some pics. The diminsions are 16" high in the back, 15.5" wide, 8" high in the front, 11.5" deep, and an angled board at the top.

 

Alright. I thought your mounting depth was 6 5/16? The box allows 6 1/2.

I leave for college in the fall as well. Where are you going? I'm from Ohio too lol

 

Yes, it SHOULD fit but my local audio store has a box exactly like it and I tried putting a cvr in it and the magnet hit the back of the box. I am going to Bowling Green State University, about 30 minutes from Toledo. Where are you going?

 

Depending on how much it fit, you could use a spacers ring around the sub cutout. I have that box but i have 2 Rockford Fosgate p3 shallows in there... They hit amazingly! hehe

 

Hontzy, that box looks pretty sweet. Did you spray paint the fosgate logo on there? I did think about the spacers but wasnt sure if it would seal up correctly. I think I have figured out the design I am going to use. It gives me .82 cubic feet of air space and then I will add some polyfill which tricks the sub. Do you know how thick the wood is in that prefab box?

 

I'm going to Ohio University in Athens

 

Hemi44, thats where my girlfriend is going to school.
