I do't have the room for a slot port this going to be a real tight squeeze . I appreciate the help this will be my first box , that i built anyway thanks for the help. 2007 Chevy Impala LS 1 Crescendo 3KWP 1Crescendo C1000/4 2 DC lvl 4 15's with lvl5 dual .7 coils 1Audio Control Matrix 1 Pioneer P880PRS 1 300 amp Iraggi alt All power runs done with Knu flex 0/1 guage 1 optima yellow top under the hood 1 XS 5100 and two Deka's in the trunk 4 Crescendo MP-8 mid bass drivers 2 DB Drive p5 5 D Pro Audio tweeters Link to comment Share on other sites More sharing options...
Decaf Posted January 19, 2009 Report Share Posted January 19, 2009 4 4" ports using the entire length of the port, which is 18," but since its a flare, only have the opening is accounted for the port length.... which means that with no modifications, u can use the whole aeroport again tho... thats a minimum Link to comment Share on other sites More sharing options...
