3 cubes after displacement is actually ok for a daily driver box.

My sister's box that I built for a single type-r 10" is only 1.5 cubes and it wangs off 400 watts. :)

yeah he wanted to be able to fit his golf clubs and a huge cooler in the back so thats what we left him with....he has about a good 15-20 inches from the box to the wall of the trunk....also i made an amp rack but just didnt get pictures of it while building it....when its all in i will have more pictures and maybe a video or 2 or 3 lol

How does a bigger ported box tuned at the same frequency with the same subwoofer and same power sound compared to a smaller ported box. Is it like sealed boxes.....the bigger usually the deeper it sounds tonally(to a point)

Lower group delay and lower peak around tuning are the two main things you will notice.

I told you that I would give you basic info assuming you would calculate it yourself... you may also want to post the width of the port or no one will be able to tell you anything about the box, but the cut sheet you posted that I gave you is ...

Net Volume: 3.04 cu/ft
Tuning Freq: 33.14 Hz
Port Area: 43.50 sq/in

as it sits... maybe someone will make changes for you to what you want for free.
