angled port? Your max dimensions would be helpful too...

its going in a impreza hatch, so around 35" wide, 30 deep, and how ever tall

have you tried to google "port calculator"? You will find some very useful calculators...

you don't want to go to wide

to much port area can also be bad

so if a 5" wide by w/e port equals 25 in^2 of port area per ft^3 it may not work well this is why port tunning is so imPORTant /rule of thumb for slots is 12-16 in^2 per ft^3 of net volume

that being said I've gone both bigger and smaller with good results and with not so good results

it all depends on set up box/subs/vehicle/imp rise/voltage/etc......

not to be a DB but you should hit up some one to DESIGN you an enclosure

you can still build it but that way you kno what the outcome will be b-4 building it so no //content.invisioncic.com/y282845/emoticons/smash.gif.499e08a4a35ffaf54f4c8194fb8fe8ed.gif after building most guys here will charge $5-15

some will do it free / some will give you simple design and some will provide cutsheets and assembly sheets (so easy ,a caveman could do it ) so it is worth it to ask for design quotes and get it right 1st time /not that you wouldn't but better to be sure

hope this helped srry to be so long winded //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

port is 5" by 12.5 inches. so thats what 62.5in^2?

box is 3.5ft^3 and tuned at 35 hz

 

[dappa5 10+ year member]

wow how long is that thing 30+ inches??

and it's not too oversized it's only 17 in^2 per cube so you good there

Here's a free design I made a while back. It's pretty much exactly what you need. The port will be side-firing, though. With your width, that shouldn't be a problem.

hey bro! u need a design right.... my pm thingy is acting all ghey!

i can shoot a design togethar right quick and accurate for u with cutsheet and simple directions on how to construct for 10 bux.... also if u wanted i can put a list of what everything u will need for construction to finish! i charge a flat $10.90 through paypal... LMK BRO!

and to explain the 45 degree in the corner of the port.... it is so the corner of the port will have continuous width and not get larger then smaller again like in a corner ....
