Well, I finally got my IB done after being in the house for over 2 months. So many other projects, and once the HT got useable, it just seemed to get pushed aside. I need some sort of line driver as I've discovered the output of my receiver's LFE jack is not sufficient to drive the pro-amp I'm using to power the sub. With all my speakers set all the way down and the sub jacked all the way up in the receivers calibration menu, I still cant get the sub up to the same level. Anyone with any ideas how to fix this, feel free to email me or respond here. Any way, here are some pictures.
