Ttime

Good news everybody! I solved the problem. This entire time there was a flap above the speaker terminals that wasn't sticking to the woofer like it's suppose to and was rattling everytime the sub moved. I feel really stupid that it's takin me so long to notice this. I do really appreciate everyone's advice though!

When building the box the port was suppose to be 2 inches wide all the way around, but somehow the corner pieces were only 1.5 or 1.75 inches apart. I can't remember for sure. That's the only part of the box that wasn't exactly like the specs. Could that be the reason for the rattling noise? It sounds like it's coming directly from the driver, but I'm new to this. I could very likely be wrong.

Okay, thanks you for the advice. Rattling mirrors is a pretty ignorant example, it's just the first thing that popped into my head. Tomorrow I'll torque it in an alternating pattern and see if that helps. Also I had some trouble fitting the speaker wires in the terminals. The terminals were way to small to fit 2 wires in the same one, so I kind of had to shove them in there... Is there a better way to do this?

Yeah I did that today... Could my box be the cause of this?

Wow, okay. I had the wrong mental image in my head. My ssf is 10-50. I have it set to 30 right now.

Well I guess I don't know how to set the ssf. I thought it would be at 30 or 32, but I don't know where to set it if it goes from 5-.15. And I don't think it's over excursion. The sub barely looks like it's moving. I'll check my head unit. Thanks for the help, I really appreciate it

Yeah I understand that, I just don't understand how something can go from 5 up to 0.15? But anyways, do you have any ideas as to why I'm having this problem?

Oh, sorry. The lpf is about 90-100. For the ssf it says it goes from 5V-0.15V, can you explain that to me?

And bass boost on zero

I used 3/4 inch mdf board. I have the gain at about 10 o'clock, ssf at 10 o'clock, and gain at only 9 o'clock without the rattle. And I put my ear right up to the sub and it's coming from the sub.

Hey guys, I'm new to car audio and just installed my first sub a few days ago. It's a 12 inch Dcon D4. I have it running at 2 ohms off of an audioque aq750. I built the enclosure using the optimal ported recommendation on the SSA website. The problem is I cant turn up the gain on the amp very much without the sub making a rattling noise. Any ideas what I might have done wrong to cause this? I know I'm not getting anywhere close to full potential out of this thing. With the gain set low enough to eliminate the rattle, the mirrors don't even move! The sound is very good, but there just isn't any power at all. All advice is greatly appreciated.
