I am building a box for my 2 kicker cvr 15's. I want the subs facing up and i was wandering where the best place to put the port would be and also what size the port should be and i was also wandering what the dimensions should be i want the box to be around 10 cu. ft. as that is what it says on the kicker website but the box can only be
41 in wide
21 in tall
26 in long
that is the size of the back of my vehicle but that should be enough space.
Please let me know and thanks for all the help
