this is my first time building a box and i want to practice on my vehicle first but need help. i know someone can. pls help me

You need to get with the sun manufacturer and they will tell you the CF of space required per sub then go from there.
I'm thinking 3 15's are a bit much for a little Caliber.

funny u mention that haha i've seen a eclipse with 8 tens in one box he took the whole back seat out and made it into a box lol. i can fit 4 15s in that car but that would be to much so thats why i'm only doing 3 15s haha.

o and the cubic feet is 2.5 for each sub that what it said from there website
