So I'm going to run 2 threat con 2 15's off a sound stream 2000, which is the best way to fire the subs and port firing which direction. 2008 ford focus sedan is the vehicle (trunk) Thanks for the help

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 :p


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?

So I've been told rear or up firing with a side port is the way to go... Sound right

that never works out in my experience unless you are fiber glassing part. I have done subs rear with port extended through rear deck that would also free up a lil internal air space I personally think it will sound like crap since theres no air for the subs to push
