i have a 15 fi bl with cooling,daily, universal and it keeps on making a scary noise, it sounds like someone is scraping the terminals of a 9v battery on the leads of the subwoofer, and its scaring the out of me, i just got the sub Friday (1/16/09) and it wasn't doing it at first

please help!

We need more info to help you, whats your amp, electrical, enclosure.

4 cubic ft box tuned to 32 hz, hifonics brutus bxi1208d a kinetik hc600 battery and 4gauge wiring running it.

4 gauge wire might be part of the problem but im not sure.

Did you take the sub out and make sure your voice coils were wired right and not touching each other?

Did you check your amp ground and power and make sure they were secure and not touching?

Did you make sure your wires going out of the amp to the voice coils were secure and not touching?

To me it sounds like you jumped the basket. Push on the cone start down and see if it scratches. if its not that it could be that you got the fomer to hot and created a bubble on the coil. If I were you I would go back to where I got it from and do a worrenty. Say that it was F*&KED right out of the box.

Dealers get a lot of DOA S&%T

Sorry to be the bearer of bad news

Is the sub still working?

yes still making the sound when it hits low

amp died??? bad RCA cable? Do you have another speaker you can try on that amp?

Do you have an ohm meter? Measure the resistance of each coil on the sub.

amp is still kickin. dont have a meter, rca cables look good.

Try it on a diffrent amp.

Also check the subsonic settings. You might be bottoming it out.

It is probably unloading. Overexcursion is causing the coil to hit the back plate. That will shatter your coil in no time. I don't see why though considering you are tuned to 32 Hz. are you positive on the tuning?

yes i had a VERY reputable business make my box for me what's underloading?

clipped power , over excursion ?

Make sure your coils aren't wired out of phase..

yes, black to black red to red in parallel

is there a number i can call them at?

look at the tinsel leads. see the patch of fabric on the cone above them? look at the patch, does it have some kind of imprint from the tinsels on it? If so, it is simply lead slap... kinda common with FI subs.

If they are embedded in the spiders he doesnt have to worry about that
