I am about to start building a new box for my suburban, it will be a subs up/port back style box for 4 AQ sdc2.5 15's. and i'm looking for some opinions from those of you that have experimented with different port locations in similar vehicles/box styles.
i posted a thread in the AQ section (here: what do you think of this box? - Car Audio Classifieds
) asking for opinions on my box design, and derrick824 brought up the idea of doing the port differently. i had designed the box with a slot port across the bottom of the box, and he said in his experience that a more vertical port in the middle of the box was a full db louder.
I'm hoping to get some input from more people in this section, so what do you think is a better setup, option 1: 5.5" tall x 46" wide slot port across the bottom of the box using the sides and bottom of the box as port walls. or option 2: 17" x 15" port in the middle using the top and bottom of the box as port walls.
here are the 2 different designs
