Porting a sealed box, any suggestions, tips?


i have 2 15" subs that call for 3 1/2 cubic feet per sub. The box i bought the subs in is only about 34" wide on the face of the box, maybe a foot deep and about 28" top to bottom on the face. My question is can i just put 2 ports in the box and maybe stuff it to help. Also how do i tell what frequency its tuned to? I dont want to buy another box cuz im gonna have a custom one made for a diff vehicle in bout a month. thanks

Why don't you try the test and see method for this one. Go out and buy two 10 inch long pieces of 4 inch diameter PVC pipe and cut holes on the face side of the box so as to not interfer with the baskets of the subs. Cut the holes so that the pipes are a tight fit press in almost the whole way and apply some silicone sealant to the outside of the PVC circumference and push in till flush mount is achieved. If it sounds like crap plug the ports with a cap and your back to sealed.
Keep it loud and clean from canada peace out.
