I've never built a box ever.
i have a crappy prefab box now, and it's doing me no good.

I have 2 12" RE SE subs being pushed by 600 watts.
I've been suggested to go with..
4 cubes @ 35 hz with 60sqin port
5ft3 @ 34hz w/ 60-75in^2 of port.

Here is the problem. I've never built a box, and don't know what I'm doing.
So if someone could help that would be great.
It's a 2003 Ford Taurus. If you need the dimensions of the trunk I can get it for you.
