Looking to build a box for two sundown x-15 d4's in a 2000 escalade.

[escalade 0]

So, I ordered two 15 inch sundown audio x-15 d4's I'll  be running at 1ohm  I have been looking for box plans so I don't have to do all the math myself! I would really like the subs facing up and ported! I have a ton of room to work with.  36" deep x 47" wide x 21" high.  of course it  can be smaller if possible. I have found a box I really like but the website that has it wants $50 for the plans. I really don't want to spend $50 on a PDF files with measurements and then still have to buy  the  MDF, glue, screws etc and then build it. So if anyone could offer some help here on building a box  maybe a website or just toss me some plans that would be great  

This would be for daily music, I listen to mostly rap but stuff like MGK, yellow wolf, suicide squad. 

This is the one I'd really like to have.  http://www.caraudiofabrication.com/#!product/prd2/1742322485/2nsf---slot-port---subs-up

 

another question  I have is since one requires 4.25 cf does that mean a box for two would be 8.5 cf? spec's below are per 1 sub.  

• Ported: 4.25 ft^3
• Displacement: 0.22 ft^3
• Depth: 10.85"
• Outside Diameter: 10.85"
• Cut-Out: 13.83"
• Recommended Tuning: 32hz
• Recommended Port Area: 68 in^2

Honestly $50 for a design is extremely high for a standard ported box.

I would get in contact with Ryan over at http://www.ram-designs.com/

 

He does excellent enclosure designs with very detailed instructions for a great price.

Thanks, I emailed him to see a price since the custom boxes aren't much cheaper at $43.  I just find it hard to believe there isnt some PDF's already floating around for boxes already for free. =x That $50 could be spent on more equipment
