how would you

How would you get rid of port noise?

[biscuitownz]

Make the port larger and readjust the length of it to keep same tuning?

By building a good box.

Post more info = get better answers.

[Cameronmyers74]

This is the box's spec, the subs are s2w8 From cadence, box is tuned to 35hz

see the "Port Area Per Foot".... you want that to be from 12-16 in^2, not 5.42, you need to pretty much triple the size of your port.

[rockFord_Expedition]

Looks like you need more port and probably a higher tune.

What power are you running to them?

here's the thread about port area

ah okay what if I make like an external port? and its being powered with 700 wrms

Edit: I can't hear the port noise in my car, only when I go to the trunk.

External ports work just fine (though I think they look funny). As long as the port area and length are correct you should be fine. You may not be able to hear the port noise from the listening position but with your port as small as it is you are probably getting some port compression, which is a "Bad Thing".

efficient boxes paired with clean power normally don't have port noise.
