larger PVC ports, need info

[truckaudioman 0]

I was thinking about to the standard square ports, but last night I thought about doing one, maybe two, larger round ports using PVC. Has anyone tried this. I was thinking something like 8" diameter ports, maybe two of them. Since it is going in a blowthrough, is it also okay to extend the ports out a little, maybe almost into the blowthrough to ensure more pressure from the port goes directly into the cabin of the truck.

You can have the port 100% external from the box, just be sure to make the overall length right.

great, thanks M5, I wasn't to sure cause I really haven't seen anyone do that, or even use straight up BIG round ports in a larger enclosure.

If you get the thick sonotubes you can even use them as ports. They come in diameters that can get huge. I have an 18" one in my garage.
