what should i use for the port size total like length and width?

 

[NissanKicker 10+ year member]

you can get away with 1 - 1.25 cuft. each...

would you reccommend aero or slot porting?

 

[NissanKicker 10+ year member]

Aero would help you since there is limited space

... But a slot port tuned @ 38 - 40hz

how many aero ports would i need and whats the best placement for them? the box is 13.5" deep 19.5" high and 38" wide.

heres a few pics

(2) 4" aeros... or (1) 6" aero

... Right down the middle.

* I'd fire everything into the cabin *

one 6inch port in the middle, and I'd fire everything to the rear.

i'd do 3 4inch ports, 11 1/2 inches long.

man this is tough, what are the benefits of porting in my situation? it fits in the little to say the least trunk of my scion xa firing towards the roof as seen in the pics.
