[QUOTE="Reggie Lives, post: 4391392, member: 549549"] mil81; no it's a single voice coil. I took out over half of the polyfill, and it didn't seem to change anything. I also trippled checked all my speaker wire (amp to box, box to sub) as well as rca connections (on amp and behind HU). Would a leak in my sealed box be a culprit? When I cut the circle for my sub, I slightly angled the cut, and one of the screws was only catching half of the mdf. After installing and reinstalling the sub a few times, the screw became completely useless, but it's only one screw and I figured the rubber surround would still seal it in. Maybe I'll try pointing the subwoofer up so that more pressure is placed on the surround, which might increase the seal and hence increase sub output? If that's the case, I guess the simplest solution is either gluing another ring onto the outside of my box or just buidling a whole new one. Also, when I first reinstalled my sub, it wasn't hitting any bass notes and would just rumble when the HU was turned out. That's when I noticed that I had a shitty connection on my remote lead, and when I fixed it the rumbling stoped. Could that have damaged anything? I'm going down to radioshack to grab a DMM to see how much the amp is outputting. This is my first system, and I really have a lack of knowledge so I appreciate everyone's input. I just find it odd that I CAN achieve the same bass ouput, but it just requires maxing everything out. Is there somethign I'm overlooking? [/QUOTE]
