Bala-the-pig Posted April 10, 2018 Report Posted April 10, 2018 Okay people so i designed this box last night and i got 5.5 cu ft after displacement. I got 8.78 cu ft before displacement. Is that too much?? Its tuned to 34 hz, subs take up.25 cu ft each and i am going to run 2 12s which are 2000 rms. Port displacement=2.78 cu ft Sub displacement= .50 cu ft Port is double layer starts off as 15" height and is 38.93" in length. The Width of the port is 7.5". Interior width=42.75" Interior length=23.5" Interior height=15" 3/4" thickness And its triple baffle.
Kraken Posted April 30, 2018 Report Posted April 30, 2018 What subs are you running? It seems to work in my eyes. Although I would throw those numbers in Torres and make sure it checks out. Alpine cde143bt/ Alpine ktp445u (4x45 amp) 2 Crescendo STS 1 (on alpine 4x45 on 2 channel mode) 4 Crescendo pwx 6.5's in front doors (Skar RP150.4) 1 Sundown zv3 12, SAE1500D. Box is 2.5 cubes tuned to 30hz.
