this box is for my brother who currently has a 2000 grand prix. her are some of the pics







o yeah my brother didnt really care about the paint...he just wanted the front and most of the top covered with it....yes its speckle paint



the spots on the box is saw dust

now i am waiting for my brother to get home to drop in the subs

finished pictures later

special thanks to rpfuror for the box plans

 
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)

 
can some one check these plans to see if this box is actually 3 cubes @ 33Hz there is a thread in general disscussion but i would like to know soon thanks

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.
