i am designing a wall in my car i know the basic design of the box and the ports. I am running one memphis mojo 15 " and four JBL Power Series P1224 12 " in a 2 door hatchbach ford escort running two kinetic 800 amp batteries on 2 hiphonics brutus amps rated at 1600 watts a piece. but i need to know more about the box design w/ the ports. of course it will be dual chambers behind the driver side. These pics are some specs i have anyone have any other ideas, port changes, etc.

why are you running a 15 of one brand and four 12s of another. you will get a lot of sound but it will be very hard to tune because each sub is rated differently

yeah i know, i could go with a 12, but there is a really small price difference between the 15 and the 12, so i'm going bigger. it will take time to tune the frequency right, but i think it will be worth it.

Why dont you just do 4 15's instead. The 4 12's are basically equivalent to 3 15's. You only loosing 3 inches of sub but you also wont need as much box space cuz its 4 instead of 5 and you can make the box one whole chamber unless you plan on porting it. if you port it you can do 2 chambers or you can even seal it and have 4 equal chambers. 60" vs 63"? when you get to that much surface area and power it really wont matter
