    your tuning in the BB program is 67Hz

    way too high

    i know it is too high...but if you look at win-isd it is 37...both ports are 10" long. i can get bb to tune at 37 but the port is half the size as in win-isd. i could understand 10-15% difference but not 50%. Can anyone help me with this? here are the speakers spec's:

    WinISD does not account for port or driver displacement

    this is what the box will look like. in BB there is a interior hole of 1.229 ,.227 for subs, and .231 for port. Then i took the net volume and inserted it into Win-isd.

    You should get the box to peak at 40 hz like this, screw around with bassbox until your graph slides over.

    looks good to me, which subs are these and how many watts, if you add a little damping it will smoothen out the curve

    there is only so much space i can use in my trunk. I have to leave enough space for a baby stroller and i am trying to leave the opening between the arm rest in the back seats for sound to enter the cabin. The amps (RF P8004 and P4004) will be mounted above the hole from the rear deck. The 2nd battery will go where the P4004 is now. Many things to go into a small space. If anyone has other ideas i am open for suggestions. Thanks

    u can also use shift+print screen and paste it into MSpaint and adjust the size from there.
