i am having the same problem understanding how to tune/port... since therules its 12"-16" , i used 14" , and my box its 4.5 after displacement. so 4.5x14= 63. 63=thats my port area ... now how deep should the port be ? i wanna tune to 33hz.. sorry for hijacking the thread but im desperate to finish my box

ok i have a box thats Height22.75 X Widht14.5 X 32.75Depth... i have a 15"fi btl wich calls for 12-16sq inches per cuft... i think i have around 3.5cubes in my box. port size would be 3.5x13 = 45.5sqinches now... i want to tune it to 32-34hz... how long should my port be ?? 26.5 inches long??? also all these number look rigth to you guys ??? i know the box its on the samll side but thats the biggest i could fit on my truck... please help me
