Hi, i have a design for (3) JL 15w6's in a 7.3 cubic feet box. It messures 15hx32dx32w. I am going to put these in a honda civic to fit perfectly. i went to http://www.carstereo.com/help/Articles.cfm?id=31 and used the port calculator and entered in all the specs of the speaker and it came up with 7.38 as the length of one side of the port. how do i build this because i've never built a ported box before, but have built several sealed boxes.The speakers specs are as following:
Vas: 10.88 cubic feet
Sd: 131 inches squared
Re: 10.88 ohm
Znom: Dual 6 ohm
Pt: 400 watts RMS
I entered all the information from this list that applied on the calculator and got that, if i'm doing something wrong, someone tell me. Here is how the box is going to look and where i want to put the port. If i have to, i'll put another port on the other side.
let me know what you guys think and help me out with this port!
