Why does it have to take up the whole trunk? What are the Cube requirements of your subs?

the recomended cubic feet for each one of my subs are 6 cu per chamber per sub.. and i will be running 2 subs...

I dont see that you will have the room to run 2 of them at that size of box, When I get to the shop I will look into it.

a smaller box filled with polyfill or similar will yeild the same results as a larger empty box.

You will not have the room to fit that box in your trunk....

and I do not believe in what you suggest Rob... IMHO thats no the right way go go about it. You are better to go with one sub and tune it properly..

yes the box will fit (if i can find out how to build it in the trunk) and still leave me with some room for my amps....
i have a box in there now that holds 1 15'' L7 sub and the box size is
35''w x 18''h x 20''d and from looking at it i can fit 2 more if i wanted to.. but i cant figure out how to build a box in the trunk.... i really need to fit atleast 2 of my 4 15'' subs as im building a competition system...

You realize that the box you need for 2 subs is going to be (with wood another 2 inches larger on each side) 74x40x44 it'* not going to fit.. I have looked at it today several times (I'm building a system for my blue car right now) and I dont see it :?

We have bonnevilles not pick up trucks

i will getterdone.

i will make a box as i already have an idea. and my idea will produce a dual chambered 10 cubic feet total sub box that will blow my trunk lid all the way to billboost'* house. (never been there but its blowing off)...

the reason i say i can make it work is because i am a good carpenter, good with math, got all the right tools and i do anything once my mind is set on it.. nothing gets in my way.

you could do a custom glass box, built in the trunk. use the entire width of the trunkand height, then leave some space int he back for groceries

mdf puts out better sound then fiberglass. MDF is just harder to shape when forming to the trunk
