Heya, I am getting ready to put a sub in my wifes 2014 Kia Sorrento. It has the upgraded infinity sound system but I need a little more oomph. I have a few different subs to choose from. I have 1 Sundown x8v3, 1 Sundown SA10 v2 and 4 Sundown SD4 12-2. I am leaning towards the x8 or sa10 But am not opposed to one of the 12s. I just think I want to build a bandpass box so as to protect it. I am going to be taking the 3rd row seat out and think there is plenty of room to mount a box and amp under there.  I will be using one of my old school amps either a mtx 225 ho or maybe one of my crossfire 30hc's. I also have a Audio Control LC2 with bass knob so I can turn it down when we don't want to bump. What do you think is the best option for my application? I would like it to be stealth as well as protected from groceries, strollers, etc. 

Thanks for any advice from a fellow Eastern Washingtonian.

Heya, I notice you live in eastern wa and know how to design a box. I live in Leavenworth and could use some advice. I have plenty of experience with the actual construction but designing a 4th order is new to me. Any advice or help will be greatly appreciated. I will be using my old school system from the 90s. The subs are 2 orion dvc 12 inch 2ntense. They will be powered by a ppi pc 2100 and an audio control 2xs crossover. 

here is a link to their specs
