testing box?

[dvldogyut 10+ year member]

i am going to build a box for testing to figure out what i want to tune to, its going to be 4 cubes for two 187 series 12's and i have some 4" pvc laying around and i am going to use it for the ports,

i will probably use two ports what will be the best layout for the subs and ports? subs up on one side of the box with ports up on other side? ports between the two subs? subs middle ports on the outside of subs?

or go with one port out each side? or both ports out on side?

Subs up port out the side but I would do 4 4" ports

4 would be too many

Subs up port out the side but I would do 4 4" ports

i only have 5 foot of 4" pvc

4 4" tuned to 28 would be crazy long!

In my ford ranger. sub up port up worked great. In my chevy crewcab, i have sub up on pass side, port to side firing into driver side back door. Seems to work really well, i have fliped the box every which way and this way sounds the best and meters the best.

when you use the bcae calculator the port lenght it comes up with for 2 ports is for each port right?
