I Want to put 2 10" subs in the back of my 07 fx4 screw. I've seen a custom box on amazon that fits 2 subs, one under each side seat and room for an amp in the middle. Anybody have this box?? Is it good quality?,enough room underneath for down firing subs?? And also what are good shallow subs that aren't too expensive??? I was leaning towards some rockfords. Thanks.

 

I don't know that box, but I have a fox acoustics box with line X on it, I love it looks custom, I got 2 10" type R shallows couldn't be happier

 

Bestbuy has a custom box for 2 10's, and for 2 12's.

 

Supercrewsound has good stuff to

 

Do you know how much?

 

I built my box so that I knew that it would fit in my regular cab. I used some MDF that I bought at Home Depot, Titebond III wood glue and some cheap carpet. There is a site that calculate the volume required for your sub if it doesn't say on it so you will know the minimum size it needs to be and you can always add some poly-fill to make it sound like a bigger box.

 

I concur. I just ordered a 10" sub box for my 08 to go under the back seat. My buddy has a SuperCrew Sounds box in his Chevy and its fits flawlessly

 

I picked up a used stealthbox and I couldn't be happier.

 

i built my own for an 8" to go under the passenger side rear seat so that the box doesnt take up all my storage space

 

Here's a shallow sub
