    Help With Ports!

    Ok I have a sealed box and i was looking for a little more output. So i wanted to port the current box i have. I was thinking that i would get some aero ports and put them on the top externally. I have two alpine type r's and my box is about 3.5 cubic feet and i want to get around 32 hertz. Here is link to a pic of my box. http://www.caraudio.com/forum/showthread.php?t=155503
    So this is the first time ive ever tried porting. I wanted to use some aero ports that i saw on partsexpress.com. Will you guys help me out on this one. Suggestions are welcome.

    Well your box can't be about 3.5... it has to be an exact volume to port it. Figure that out, come back and post it.

    I'm guessing they are 12's.

    Use two 4" ports 13.5" long. It will be 3.35ft^3 tuned to 35hz.

    A bit small but should be ok.

    Edit - Oh and that is with the ports in the box

    Out of the box you need the ports to be 12.75" long

    This is before driver displacement also...

    Is it going to be worth it? Because I really dont want to cut up my box if im not going to like it. I know its one of the things that i kinda have to do and find out but i was just wondering if you would do it?

    Considering aero ports are kinda pricey, I'd just go ahead and pick up a sheet of MDF and glue instead and build a ported box from scratch. You would be able to make it bigger and probably sound better than just adding areo's to your sealed box (probably less than optimal volume to port). But thats just me..
