How wide do i need to cut the hole for them...

Their website says this....

"5. Once placement has been determined cut the proper size hole. (Cut hole to the diameter of the flare side of the inside flare)"

So i was wondeing if any of you have worked with them before and know the exact size needed to be cut for a 4 inch one. Thanks, Andrew

6.25" cutout diameter.

7.25" outer diameter.

I know because I've used lots of these and I've emailed PSP and they told me the same.

cool, so 6.25 for the whole. so that mean the flare that goes inside the box is smaller then the flare on the out side since the smaller one has to fit in the hole and the one on the out side is 7.25 in dimeter right?

Yes, the outside flare (where you screw the port in) is 1" larger in diameter than the inside flare.

Nope, even if you cut the hole a tad smaller than it should be, you can tilt the port and "edge" it on through if you know what I mean. It has a little (very little) flex that helps with fukc ups like those //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif
