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

    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

    Re: Port and firing question

    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.

    Re: Port and firing question

    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?
