haha good luck with that box buddy. You're gonna need to loose your back seat if you want to even consider a ported box

 

2 X 12 L7 will definetly occupy your whole back(including 3rd row sit space) to get the right cubic inch for them subs.
also...make sure that you get the dual 2ohms so you can wire both subs to carry a 2 ohm load to fully utilize the amp.L7's are power hungry and they will sound like crap if not fed with the right amount of power.

 

well with those dimensions it will give me 6.5cu ft and take away the .5 for the subs displacement and then even say 1cu ft for the port gives me around 2.5 per sub that isnt enough the max reccommend is 3.25

 

those dim's do not add up to 6.5 cu ft, 5.33 before sub and port displacement. and with how low you want to tune your looking at around 3 cu ft of port

 

so i will have maybe 1cu ft per sub
well some guy at car audio that said he could build me a box with those dimensions and that tune and be 2.5 per sub wow i am lost in how to get 2 12's in my truck

what if i go with the max dimensions being 26 long 35 deep and 17.5 wide
whats the biggest subs i can get in there can i get 2 12's or 2 15's, or one 15 and what would be the loudest

i am trying to get a box to sit in place of my rear console in my KR and i dont kno if its possible i am so frustrated

 

I play a lot of cards... So jack ace.

 

3cu ft of Port?!?


And interior dim is 5.935cuft. all ports need to stay under 36 inches in length.

 

ok so how about these dimensions
30deep 26long and 17.5wide
with aeroports tuned at 34hz is that enough airspace and how would it sound

 

check your math again, I get 5.331 interior before sub and port disp

port would eat up about 1.5 cu ft, I accidentally doubled the port numbers

 

so how about the new dimesnions i threw out there with the aeroports

 

would be about 6.46 cu ft tuned to 34 with 4 areoports. make sure you use a subsonic filter tho

 

ok sorry to sound dumb but whats a subsonic filter and how do u use them
and also why 4 aeroports
go to this link this guy has made me a desgin what do you think of it

http://www.caraudio.com/forum/showth...=282680&page=3

also one more question the lower the tuning the louder or is it the opposite
also whats the difference in normal port and aeroports pros and cons of both

 

you could go with 2 6 inch areo ports but I think the tuning would be like 35-36ish

 

ok so go with 4 4 inch or what
do you build boxes or kno somone who would build me the best box for me

and also whats the difference in normal port and aeroports
and subsonic filter is on the amp correct how do i use that

 

anyone
