    Can I turn my sealed into a ported?

    This might be a really retarded question to many of you but maybe, it can be done? Im terrible at figuring out enclosure volume and aero port size that I need.

    I currently have 2 12" Type R's in an enclosed box underneath the back seat in my silverado. I am pretty sure I dont have the right amount of Volume to drill Aero Ports on each side of the box, but I just thought I'd ask.


    This is the current box in my truck.


    This is my box measurements. Would it be possible to drill aero ports on each side of my box to make it ported like in the drawing? My box does have a divider right in the middle.



    thanks in advance for any advice and your time.

    Are the subs sharing the same space?

    Just drill like 50 1" holes in the side, that will put you roughly around 34.7625193hz

    You're welcome.

    Re: Can I turn my sealed into a ported?

    I just calculated the volume (roughly) and I got about 1.7 per chamber.. For a pair of type R's, you might be able to get away with a 3" aero per side at roughly 9" per side for roughly 32hz tuning.. This is the only thing you can do if you want to keep that divider.

    Re: Can I turn my sealed into a ported?

    Really appreciate it bro. So im looking at a 3" aero port at 9" long, on each side?

    With my quick, rough calculation, that is what I came up with. Others might agree or disagree but it should be pretty close.

    I was thinking 2.50,but ? Port those subs, and get them to sound better..I think you will be fine to do..shared chamber would have been a bit trick/or not able to as well with that center hump

    On the port diameter or box volume? 2.5 might be close for a shared chamber but they are divided. I calculated these volumes using a .75" thick wall as well. I believe it is pretty close. about 1.7 per chamber before sub displacement.
