JesseyMclame Posted September 9, 2014 Author Report Share Posted September 9, 2014 So this is my box design. I'm trying to figure out how to calculate how to make the cuts for a 14.5" port. I think that calculator you showed me would be more for finding out how big to make the port, right ? Current setup in my 96 Hoe Hu - Pioneer DEH-80prs. Amps - (4) Crossfire C5 1700D's, MTX Thunder 5604(mids), PPI Art 300.2 (tweets) Batts - 4 91ah rear batts, 50ah batt up front. Subs - 2 Crossfire XSv2 18's Alt - Singer 330A Front stage - Random JL & Eclipse mids, Eclipse tweets Link to comment Share on other sites More sharing options...
Joe X Posted September 9, 2014 Report Share Posted September 9, 2014 In the Torres you show port area is 165 square inches, you use that on the online calculator to obtain A and eventually B with the formula on my last post, that will give you the cross-sectional shape of the parts to build for the octo (but not the length of the port itself), the only problem is that Torres cannot calculate the displacement for octoports so unless the port is fully external you will have to deal with that yourself.
