Woofer making horrible noise! HELP!

I just got a 12in. alpine subwoofer that is in a sealed box and is powered by a 500RMS watt alpine amp. It is making a really loud knocking noise when there are low bass tones. I talked to best buy and they thought it might be in the wiring but i hooked a different sub up and it sounded fine so it is deffinitally the sub. Is the sub shot even tho it is brand new? or is it fixable?

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?).

Amp makes noise. I am purchaseing a new amp

Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

    2 12" Hitron 600w subs in a BandPass box

    Remember that driving a load with an underpowered amp will probably cause more problems than having a more powerful amp that is not running flat out. 200-300W amp would be ok, but I would suggest going for the biggest you can afford. If you crank up the volume on the smaller amp you will probably get a fair amount of distortion, which may actually damage the speakers. A larger amp will not give as much distortion for the same loudness/volume and give better control of the speakers for a tighter bass..
