Gunz That Turn on Nunz
The tube will be half inside the box and half sticking out. It should be 2-4 inches away from the back wall of the box and sticking out. Ends should be flared to prevent port noise. The length determine the tuning and it correlates with how big the box is. So there's a whole ratio you need to work out.Also why would you have the pvc pipe sticking out when you could cut it flush with box, does it amplify the sound the longer the tube is.Thanks
thats for your door speakers. Not gonna be anywhere near enough for your subwoofer.Do you by any chance have a pic of another car with the pvc port, just to see an actual pic with it, I also have a 4 channel soundstream 940 I believe, I dont know how good it is thou.
