I have a slot ported box in my trunk, and when I open the trunk lid up, I can hear a ton of port noise coming from the box. Is there anything I can do to reduce this?
Yeah I wouldn't worry about it if you can't hear it from the driver seat although you might be able to help things a bit if you radius'd(smooth) the outside and inside edges a bit.
High velocity air passing over those sharp edges creates lil vortices which is whats making that chuffing noise.
i wouldnt open the trunk if i were you for an extended period of time with the music playing because the subwoofers get too much air and they have a lot greater chance of having to be replaced
Ok. You don't know what your talking about man. It's not free air. The sub is still in the box. I think some1 else said that once and every body laughed at him.
