Starting first build, 15" DC Level 5, someone double check my specs ;)?

[Stephen Dunnington]

1 15" DC Level 5: 3500 Rms

AQ3500

Box:

Wx30.75

Hx16.5

Dx15.75

Port:

3" Width

41" Total(16 Inches per cu)

2.5cu w/.25 sub displacement/ x amount for 45's

Tuned at 32 hurtz playing low end music constantly.

I just want to see what else I need to do, I feel like 16" per cu isn't much

its not really about box size compared to port size. its more about the sub on what the port needs to measure up to. im personally still learning on this and cant really answer any questions.

best i can do is suggest looking into port velocity and reading up as much as you can about it. to much and you get noise from my understanding then to little and you lose output.

anyone...? would a 3.5" port be sufficiable?
