Port rear subs rear or up. Could try port side firing as well.

im just wondering how.u can get 2 properly ported 15s in. ford focus ..i cant even squeeze that in my impala

well either way a proper size box for those 15"s wont give you a lot of room for the port to make any difference in any direction. It usually "louder" firing rear, with a minimum distance of 6".

I have my port for 2 12s' facing rear and subs up. I don't have rear speakers so they fire into the grill. Works good

subs back port back would be the best. gunna be kind of hard to port 2 15s unless you have a big trunk. I can try and design you a box if you send me your max dimensions.

Ok so I just put the exterior dimensions in a box calculator and says I have 10.85 cubic feet, that's taking in the factor of the 3/4 box materials, but not the port, bracing and sub, and the TC2 15 says 3.5max per 15, so that is a total of 7 cube for both, leaves me 3.8 for port and sub displacement, please correct or let me know if I am doing something wrong here, thanks

Btw thanks for the comments from everybody already.

This is what I got.?

Width 41"

Height1-32"

height2-21"

Depth-20.5"

Thickness-.75

Inter vol= 10.85793 cu ft

Different body styles but I can bet money that you measured the inside and not the trunk opening... I did that too the first time


My max focus trunk openings are:
15 height
30 width
23 depth (if rear firing, 27 if forward or up firing)

Please don't take offense, but have you never built a box in the trunk, or do you just build outside then try to put it in the trunk?

Thanks, I was planning on assembling inside the trunk
