FreeZzy Posted December 10, 2013 Report Posted December 10, 2013 Hello. i want to buy 2 RF T2D215 and i make a custom box for my BMW F02, but i'm not sure if the box looks good or not so that why i asking here what do you think ? Here is a picture of box Spec of box ( not final size i want tuned at 30hz ):
alaskanzx5 Posted December 10, 2013 Report Posted December 10, 2013 That box calc is not accurate. For a slot port though you want roughly 3.25 cu ft per 15. That 5.5 cuft net after sub, bracing, and port displacement. Forthose subs you will also want a double baffle and around 170" of port area. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
alaskanzx5 Posted December 10, 2013 Report Posted December 10, 2013 Didn't even look at that lol. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
FreeZzy Posted December 10, 2013 Author Report Posted December 10, 2013 Sorry but i don't understand ^^ i from france so it's little bit hard for me to understand all what you say size of trunk is: 52cm height ~78cm width 80cm depth on top and 110cm depth on down
alaskanzx5 Posted December 10, 2013 Report Posted December 10, 2013 The box has to be able ti fit into the trunk. That box calculator isn't accurate. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.
FreeZzy Posted December 10, 2013 Author Report Posted December 10, 2013 okay, so do you think you can help me to make a good box or tell me how to do ?
Guest Posted December 10, 2013 Report Posted December 10, 2013 first things first. get dimensions of your trunk. dimensions that you would be able to fit the box through the trunk opening, or to build the box in the trunk (hopefully facing forward if you do that because choking the subs against the trunk lid is pointless).
Joe X Posted December 11, 2013 Report Posted December 11, 2013 FreeZzy if the dimensions you give are right, the box will have to be made inside the trunk.
dblovah51 Posted December 11, 2013 Report Posted December 11, 2013 3.25 per sub and around 55sq of port each tuned to 35hz. who ever said 170sq of port is crazy. 2004 trailblazer 4 FI BTL 18s (2) DC 10.0k xs power d3100s mechman 270 158.2 @41
