suggestions for port tuning

[Sepheran 10+ year member]

im building a new box to save trunk space.

ive got a 15 and 2 12.

im thinking the 15 would be good at abot 25 to 30 hz for tuning in a 3 cuft box.

and the 12 around 35 to 40 hz each in a 2 cuft box a apiece. tell me what ya guys think any help or input would be helpful

NO! NO! NO! 3 cubes is not enough to tune that low with a 15....if you are goin to run the 15 in a 3 cube box...tune to 45....if you can get 4.5 out of the trunk then 35 is possible

ive got the trunk of a Cadillac deville so i could get 4.5 out of it probably

i want to get uber lows from the 15 and decent highs from the 12's

 

[cj407]

so you want to run all 3 subs in the trunk?

Please tell me this will be for two separate vehicles. What kind of subs do you have?

isnt that a lil backwards...if you want to save space wouldnt you go with smaller subs.

ok im already running this system at this moment and it sounds great i just want to build one box with 3 separate compartments one for each sub all ported

right now i have my 15 in a 3 cuft box tuned to 18 hz and my 12,s are in a sealed double box

it takes up my hole trunk so i want to reduce the amount of space thats being wasted by the double box

was a bit of a pain the get the crossover set right for all 3 subs

yea good luck with that one...1 amp 3 subs...this is just a joke

 

[Sepheran 10+ year member]

ok when did i ever say that i was only useing one amp

for your information i have 2 amps at the moment one for the 15 and one for the pair of 12's

don't assume things when you don't know the full story

 

[cj407]

ooh my bad...you big balling with 3 subs in the trunk of different sizes and tuning.....GANGSTA!!!!

don't ya'll know its cool to have 1 15 and 2 12's in your trunk....

[Sepheran 10+ year member]

yeah what ever guess none of you ever think outside the box this is the worst forum ever no help what so ever guess you just dont have the knowage to design something that breaks the mold

 

[cj407]

breaks the mold....im already breaking the mold with what i'm doing with my car....so try again....your just a noob and dont know jack about how sound waves work...go back to the flea market/swap shop and pick up some more garbage boxes....

lmao @ "uber lows from the 15 and decent highs from the 12's"

they are subs....they play below 150 hz....not HIGH's unless you have 12" tweeters....
