OK shacksters. I DIY'd my 315HF-4 Dayton 12" driver. The box is ABSOLUTELY perfect, except for the fact that me and the guy building it got lazy, and drilled holes in the back to feed wires through. On louder volumes, I can feel the air coming out and hitting my face near the holes. In the higher range.. 80-90hz, I can hear some sort of 'resonating' or maybe its actually soundwaves escaping from the back of the sub. It sounds a bit funky. So should I get speaker terminals? or just apply silicone to the holes and seal them that way? thanks for the help guys.
