Re: I HOOKED UP MY SUB AND NOW ITS MAKING A loud...
Try taking out your rca leads and turning the amp on. if it stil makes the noise try using a diffrent sub 2 see if the sub is gone. mite be broken leads.

I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.
If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.
is it sitting next to any power source if so remove it away from the power source that will not make noisethe sub is just making the frequency noises from electricity
You need to be much more clear, and provide a lot more detail if you want help on this issue. What brand/make/model sub woofer? is it a powered or passive sub? what is it hooked up to? how is it connected? what is the audio source? what sound is it making? Please be specific in all details.
You did not specify what type of enclosure the subs are in or if they share the same airspace. But the sound you describe sounds suspiciously like the enclosure is at fault and not the sub itself.
Remove and reverse the subs in the box and test for the noise again. If the noise is still produced on the same side of the box, it's the enclosure. If the noise follows the sub, then you have a problem with that sub.
If the box is making the noise, and it's a ported box, you probably have "port noise". If it's a sealed enclosure, you could have either an air leak or flexing noise. In either case, repair the enclosure or put the subs in a new one. If the sub itself is making the noise, there probably isn't much you can do. Most likely some part of the voice coil assembly is touching where it should not.
the voice coils are blown and they would replace the the whole cone and coil assembly, it is almost as much as buying a new sub, email me I am a car audio wholesale dealer and I beat any price ( with full factory authorized warranty !! ).
Think as an expert...
Probably from my experience repairing woofers etc... the cone (1) or the spider (2) isn't well glued onto the woofer skeleton(or both???)
The woofer cone must be absolutely centered or else you will get those clicks in low frequencies(you also get them in higher frequencies but you can't hear them!)
I must say that it is very difficult to repair a woofer by your own.
I suggest to return it back where you bought it and take another one (i suppose that you have a guarantee ha?).
