Audio Systems: Box for 2 Kicker Comp 10 4Ohm 150RMS Each, chevy caprice, divider wall


Question
I bought 2 kicker comp 10" 4ohm 150RMS(300 max) each subs. Should a kikcer mono 300rms amp be ok to power both of them in parallel at 2ohms? I decided to build sealed box because I am new to this and don't feel like wasting time and money. I have an 84 Chevy Caprice, so I have plenty of trunk room. Should I build a single enclosure for both or seperate or can I build a single enclosure with a wall in the middle? Kicker says to use 2.4 ft3 for a single enclosure for Maximum enclosure volume. What dimensions should I use(HxWxD) for my box? Any other suggetions you have would be appreciated. Thank you for your time.

Answer
sorry it took so long, I was on vacation and forgot to check the box that I was away.
Yes, this seems like a great match.
As for the box, this is a pretty big box for 10s.  I think about 2 cubic feet per sub is all they should need.
The best way to build it is with the divider wall in the middle.  it isolates the subs and also stiffens the box.
The easiest way to figure the dimensions is to measure the maximum legth the box will be and the max height you want the box to be, remember to allow for clearence to get the box into the car and if it has to be turned to get it into position, etc.
once you know the lengh and height subtract off for the thickness of the wood. so if you box is goign to be 48" wide and 15" tall and have a top, bottom, left, right and center divider and you're using 3/4" thick wood, then your calculation would look like this:

48" - .75 (left) -.75 (right) -.75 center = 45.75 (total internal lengh)
and each sub will get 1/2 of that lengh so divide by 2:
45.75 / 2 = 22.875 (internal lenght per sub)

now find the internal height again using the example that our box will be 15" high:

15" - .75 (top) - .75 (bottom) = 13.5" (total internal height)

Now multiply the height and lenght together:

22.875 X 13.5 = 309 sq inches.

Now all you have to do is calculate how deep this box would be.  we said your box needs to be 2 cubic feet per sub.  to convert cubic feet to cubic inches you just mulitply by 1728:

2 X 1728 = 3456 (total cubic inches each sub needs)

so the final step is to divid that total by the sq inches we came up with and that will tell us the internal depth out box needs to be to come out right:

3456 / 309 = 11.2 inches deep

Remember this is internal so if we add the thickness of the wood we get:

11.2 + .75 (front) + .75 (rear) = 12.7" (outside depth)

so just take your lenght measurment and height measurment and throw them into these calculations and it will tell you how deep to build the box to come out right.
If youre using braces inside the box those have to be calc'd in too, and its a good idea to either add a little space to compensate for what the subs take up (like .06 cubic inches) or just add some stuffing inside the box to compensate for that.
Good luck and let me know how it goes please!
