jonathancullen89 Posted July 11, 2008 Report Share Posted July 11, 2008 alright so i am building a box for my brothers friend's two 15" ma audio subs, its like 7.3 cu^ft and i need help with the port. i think i didnt this wrong last time and thats why my last subs sounded like shit. i used the calculator from carstereo.com but now for my question. when building the port lets say i put a 6x7" port, now is that the inside port area or so i make the port 6x7". if you dont understand one would be outside dimensions other would be inside demensions. im almost done with the box. do you think 6x7" is big enough for two 15"? im not really sure. any help or suggestions would be great. thanks everyone 1992 cavalier build 1992 blazer s10 kenwood cd hifonics hfi2500d 6 soon to be 12 12" hifonics hfi12d4's shit ton-o-wire Blurred Vision Audio Team SMD feedback/refs. clicky!- Link to comment Share on other sites More sharing options...
