you probably dont want to put your port directly behind tour subs. you will create very little pressure and not get loud... try to design it so the port is at least 90 degrees with sub

O wow...I can barely get my box for my 12s in my grand am trunk...and the 2 cars are almost made the same...

Hope you plan on building the box in the trunk :santa:

Also yea...port in back = bad.

Think really the 2 best places to put it would be the top or front...I THINK the top...not too sure about that though

yeah are you sure that box is going to fix through the trunk hole? or are you gonna do an in-trunk build? and I didn't think you could fit 2 18's back there with proper airspace but then again I could be mistaken.

i may be wrong but it looks like the front of your box is only 17"mtall...so how will your 18" subs fit???

^ x2

edit: if you look its actually the true height so the angled piece would be a bit larger

ya i saw that but i couldnt tell for sure....well its only 36" long and the two subs are prolly about 38" side by side if you get what im saying...it needs to be like 40" long...or am i wrong again :(

well the subs arent going to be exactly 18 across...will prolly be 18.5--19.5" across so 36 wont work IMO but i could be wrong...
