think about what who said?
mark personally told me that 6 cubes would be fine for the 2 subs with my amp, the amp used to be his, he knows and has seen my car and knows its for daily so 6 cubes is what i would do to start with, and go from there.

 

I think 6cubes is excessive for 2 12's LOL I would prob do more like 4 cubes, but hye give it a whirl

 

6 cubes sounds like a pretty standard box for subs that require that much power.
I hell in my house i have 2 15inch speakers with 9 cubes a piece.
100db @ 1m@ 1watt@16ohms.
Real speakers need real bockses.

 

Pretty funny u say that as I see many REAL subs in smaller boxes. It isn't a need but do wut some dude told u and build 6cubes! If u are just gonna defend opinions don't ask for it!

 

I have 2 12" subs in my truck and they each have their own 3 cub box tuned to 34 hertz, they sound wicked in that set up. Subs are Pioneer TS-W2000SPL.

 

this dude just happens to be the man behind the company kinda knows a bit what hes talking about

 

I agree you can use a 6cube box and sound great but as I said its NOT NEEDED!
I have seen taht sub single 12 in 2.25cubes it sounded fine.

 

Ya mines in a 2.2 box right now, but chances are I'm going to do a 4.5cube box, just gotta figure out my port specs

 

its really all based on the person and how they like there sound! I cant say if a 6cube box will or willnot sound good, its up to your ears LOL I am used to hearin my boxes @50hz so low stuff aint my fortee! but that is a monster box for your car LOL. I could see maybe in a suv

 

I calculated trunk space in my moms sunfire trunk and it came out to 16 deep 22 wide and 30 long, Get a calculator and that makes roughly 6.1. THen MINUS walls which Iwill be using 1" mdf. still comes out good pretty high. Thats without using any cabin space and leaving quite a bit of room for sub. If you want deep clean QUALITY sounding bass, go for a bigger box. If you want something for SPL then im sure you can do with smaller. I was thinking about taking out a round section in the middle area of the seat and vent into the cabin. Use WINISD its free, but may take a while to figure out.
