I just got this sub hooked up in the back of my car (two 10s but just testing with one) and for some reason it made some strange noise everytime it hit a certain way. I reverse mounted them, and I heard that is somewhat bad for quality, but not substancially, so what could it be. It sounds as though something was vibrating.
1. How high do you have your gain set? You sure your not clipping your signal? (if you don't know what that means: it's bascially when you ask the amp to put out more power than it can produce, therefore, distorting your subs.)
2. You sure it's not something in your car vibrating? Also, is your box the right size and built good?
3. What kind of amp and subs do you have, and how do you have it wired?
how long were u testing the subs...and r u sure u wernt clipping them for long....cuz i messed up my MB quarts PWE-354 subs and a peice on the inside of the sub is vibrating(dont know whut its called)
yeah but the last 2 question would b able 2 help us out more
it's possible.....could sound like the sub is vibrating, but just make sure it's nothing near it vibrating. Also, if it's out of phase, then it won't sound like it should either
i have audiobahn (I heard they were OK not they best though)A8000T amp, and two AW100T subs, only one is hooked up. I just have a wire from the positive on the amp to the positive on the sub and same with the negative.

audiobahns make weird noises if the gains out of whack... same with using bass boost...
i had a problem for the first couple weeks but it went away.... it sounded like the sub was bottoming out.... i guess it just needed time to break in...
it might be lead slap to, thats where the tinsil lead to your vc is hitting the cone, when its playing put your finger on the cone, if it makes the same noise then im pretty sure its lead slap, but it could also be distortion, or it could the awful sq audiobum subs make.LOL
ok so how do I check those... Dustin: I have put mty finger on it, and it does still make the noise, like something is viberating. James: How do I fix this gain problems? if the gain is that little "mi"/"max" thing I have set half way. the LPF is on, but i am not sure what do set that too. Other James: How do I check this gain? and the sub sonic switch is off
yup, the gain is probably that max/min thing you see. Is there any numbers on it? If so, that has to match your voltage on your head unit. For example, if your hu is producing 2.5V, then your amp's gain must be set to 2.5V. Try turning the sub up to where you normally have it, and turn it down a bit to see if the sound goes away. Also, try what Dustin said too. Must to this by the elimation process
unfortunately there are no numbers, just min/max, the only thing that seems to do is make it loader or quieter depending on if i turn it clockwise or counter clock wise, also I do not know the voltage of the headunit and the sound is only there when it hits almost at a cetain way, when the bass is sharp, I guess would be a to point it, i did put my fingers on the cone, it did the same noise, how is lead slap fix, and is there anyway to check besides that?
also, I just did the cone test again and it didnt make that noise... (i thought the cone was something else, but if I touch the cone with alittle force, it doesnt make must virbate noise... so what does that mean and how can I fix it?
I believe it miht just get too much power (it WAS supposed to be hooked up to two speakers) and when I hook the other up, (before it blew) it sounded good.
