4 12 l7s in a bandpass box

any body have any ideas on how i should build it so it can fit in my 97altima the trunk is big is jus once u make it outside u cant fit it in trought the back. someone told me i had to make two seprate boxes put them in and then unite them inside i need 1.3 cubic feet for each l7 chamber and 2.6 for ported chamber any ideas will be greatttt

Do you have enough room if you take the rear seat out and put it in that way?  You would also have to measure the door opening.  But I'd say you should definitely design a box that will fit in without assembly withing the car itself...you want to be able to remove it.

Maybe you could build two separate boxes and keep them separate.  There might be room enough through either of the openings into the trunk to load one at a time.  That's the way I would look at this project...

trough the back seat i have 25 width by 15.5 hight and langth i can do as much as i want mayby i sacrafice w and h and get the internal volume by the langth
