Its actually going to be alot wider if you use 14-16 cubic inches per foot. Your looking at 99-140 inches of port area.
Remember an 18 moves alot of air so a big port is ok
i get that but whenever i see boxes i never see the port being more then maybe 4 inches wide. am i calculating port area right? Port h*w
-
port area is too small, do 14-16 sq inches per cubic ft.
for q daily it needs to be that big ?
-
so it doesn't matter how wide the gap is cause thats what i'm worried about.

i'll be running a aq1200 if that helps
well i've got this 1" board of mdf that i could add as a second baffle i'm pretty sure there is enough wood. would that be enough ?
-
so i designed a box for my fi q 18. its 7.1 cu f before displacement which is .25 or something close to that. this is going to be a sub up port back setup.
using 3/4 inch mdf
dimensions
34 width 14 height 32 deep (inches)
Port
6 wide 12.5 high 24 long (inches) port area is 75" is that a good number. and i feel like 6 inches wide is really big. will i be ok? Someone told me i should have at least 80^2 of port area but to achieve that my port has to be 6.5 inches wide and i feel like 6 is already to big so i thought i'd ask.
alternate Port with *81^2
6.5 wide 12.5 high 26.35 long
also do you think i need internal bracing? if so where, how, and what kind?
-
nice looks very well done imo not that i know much but it looks good.
-
hehe um look in sig for real internets
but real i would suggest just pausing it. i guess you could try setting the display for you 360 on a lower res just while you play movies and see if it will also trick the download thinking it doesn't need to play in i high res. just a thought -
who knows i'm thinking its coming because of the singles though.
-
Is any one else just waiting for him to drop this album already. been like ten years now he's just teasing us with singles.

My DD 2512 plays down to 24Hz with authority....it'll go down to 22 Hz or so but any less than that and I can't hear it anymore. Not an air mover though, 1 12" in the trunk FTL

if your looking for low budget look at aq's new line of sdc's 2.0 and a aq750 or an aq1200 and some sdc's 2.5's if you would like. aq is great you won't be dissapointed
-
so someone finally recommended me a box calculator. does that look good opinions/suggestions.
do you think 7.9cu is to big??
-
good call
-
i can make ^^^this work thanks man.
-
good to know. i'll probably stick with on the box with odd headed screws for security reasons. haha so what 7-8 cubes then
-
so its not possible then damn i was excited
-
i could put it under the middle row maybe but i figured it would get to hot under there
-
really no one ?

hey so i saw a video a couple years ago and i just can't find it. any way in said video this guy had strips of what looked like little led lights and they were attached to his wire just like taped on with adhesive or something on the back. they would light up with his base, i'm assuming that it would sense to surge going to the amp or something. it would look sick to have my trunk light up when ever my subs hit.
i didn't think that was possible. if it is and any one knows what i'm talking about throw a link up cause i want some haha.
if that doesn't exist i'd still like to know how he did it if someone knows how.

i'm waiting haha looks sick

so i'm new to car audio and this will be my first box.
sub: fi 18" q extra spider displacment .24 mounting depth 10" https://ssl.perfora.net/www.ficaraudio.com/sess/utn154d8e3b9096029/shopdata/0050_Speakers/0030_Q/product_overview.shopscript
amp: aq1200
space: i have an acura mdx its an suv 46" x 41" x 18" (would like to keep it below the window) plenty of space 15 cubes it a did my math right. (which i doubt)
goals: to be as loud as possible while still sounding good. and be able to play all kinds of music decently and beat the lows. ( if its possible to have both )
i'm thinking about going sub up port back as i've heard thats the best combo.
my questions: should i use the full ten cubes maximum that fi suggests. will it still sound good. and if i do tune it all the way down at 28hz like the website says will my sub still be able to play rock or those higher notes on dubstep. or should i tune higher. will my sub be able to play fast and "higher" bass notes if i tune that low. how many sheets of mdf will i need. whats the best wood glue.
can i mount my amp on my box or will that ruin it? i was thinking about using the extra mdf and attaching it to the back of my box. (away from eyes tomards the seats) just two strips as ten by four to mount my amp on either end so that there is air flowing through the center. and mounting my amp to that. good idea or bad idea. ?
thanks in advance.

ok cool thanks. so a double baffle will be enough for strength no other bracing ?
