Hi, I am needing to figure out how to build a box for 2 Rockford Fosgate T1 12" Subwoofers for a 2013 Mustang
GT Premium. Since the trunk opening is so small I am being forced to build the box inside of the trunk which will be very challenging since I have zero experience in subwoofer boxes and this will be my first setup ever. I am planning on having the two subs hooked up to a Rockford Fosgate T1500.1BD amp and a AudioControl LC2i so i can use my factory radio. I want a really clean and professional install so i want to cover the box in carpet and really do everything i can to make the subs, amp, box, and wiring look very clean. The main problem that I see is that i have no clue how to build the box. I want a ported box. I don't know if i should make a flared or slot port and if i should have the subs share the space and maybe put supports in the box to reduce flex or if I should just separate each sub with its own air space. Is their any way someone could look at the subs and the dimensions of the mustang trunk and make the best possible rear firing ported box design and give me the dimensions for everything and tell me how to make it. Sorry for the long post but Ive been doing research for weeks and still cant figure this out. Thank you guys so much for the help. Hope y'all can help!!!!
