Aero Port size / Port noise

[ZEROohms]

Hello,

I'm looking to build another enclosure for my GMC crew cab, since I've been experiencing alot of port noise with my current enclosure. Due to the lack of space (located center console) I'm thinking an aero port will be the best.

I have a gross volume of 1.55 cu.ft. 

Subwoofer - RE Audio SX10

Amp - Boston Acoustics GT-2200 (900w @2 ohms)

I'm wondering if i should go with a 3" or a 4" aero port. It seems like the 3" would be the more reasonable option for the space, ~12" port length when tuned to 32hz, as opposed to the ~24" port length with the 4" tuned to 32hz. 

With this box, I do not want to experience any port noise. What would you guys recommend?

Thanks,

Brian

Details on the current box specs?  Pics?

This is the current box, I would like the new box to stay within the same footprint.

With a flared port, the box will be noticeably smaller than the one you currently have.  Whenever I make a ported box, and spacing is limited, I use flared ports instead of the conventional slotted port design. You should be fine with a single 3" port.

I dont think a single 3" is going to be enough for 1000w rms 10. I would definitely plan on using the 4" if your already experiencing port noise.

Single 4 inch or 2 3 inchers if you're concerned about noise.
