Im looking to build a sub box for my truck to go under the back seats. I have 2 JL audio 10W1v2.4 10" subs. Their is not very much room under the seats. I am wondering if i should go with a ported or sealed box. or if any one has some plans for boxes. The truck is a Ford F150 1997. Here is a truck with a sub box the same as my truck for a better idea.

id like to have the subs facing up unlike the on there.

 

ported is the better way to go but there bigger in size

 

The EBP of those subs is ~58, so a sealed box should work fine and would allow you to keep the size to a minimum.

How much room do you have to work with?
