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

[Julian 641]

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

[Juslivin 1]

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

Is the sub still working?

[Julian 641]

yes still making the sound when it hits low

[BKOLFO4 29]

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.

[Adrian_D 520]

Try it on a diffrent amp.

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

[Duran 387]

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?

[Julian 641]

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

[justin smith 0]

clipped power , over excursion ?

[johnecon2001 82]

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

[Julian 641]

yes, black to black red to red in parallel

[Julian 641]

is there a number i can call them at?

[cx-7heaven 7]

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
