I'm looking at the drawing for this alignment and just want to make sure on a couple of things. First, the left side for the ports and the right side for the sub? Does this make any difference on this part? Could the ports go in the front with the driver to the rear? Secondly, the ports..The specs mention 11 inch tubes. I take it this is measured from end of flare to end of flare? Or does that mean the tubes themselves without the flares? Dumb questions I'm sure but enquiring minds would like to know. I'm making sawdust right now, and everything is here but the amp. It should make it by mid week. Thanks in advance for your replies.
