Blowing subs???

[torn eMericas 10+ year member]

Is basically the only way to blow your sub is to let it distort and continue to play it at high volumes? I havea 450w amp and a 400watt sub, and on some songs it gets distorted at only about 30% volume, where other songs will go to 70% and sound fine. Not just distorting, on a couple of songs i hear kind of a popping sound, not clean bass, but where it sounds like the cone is popping or some crap.

There are several ways, Like this:

how high is your gain set?

The cone popping could either be the sub bottoming out or the coils leaving the gap.

What's your setup?? Subs, box, amp, gain settings, etc.

Sounds like your gains are way off.

kivker sx 400.2 amp and the gain is set at 11db out of 12 and i have a 12'' cvr

maybe i need to lower the gain??? the low frequency slope is at 12db

There are two general ways to blow a sub, mechanically and thermally. Mechanically is bottoming out the voice coil or suspension. Thermally is simply applying too much power for the driver to dissipate, either rapidly as in a high powered burp or slowly as in degredation of the components and glues.

cvrs pop, nothing is blown, that is just how they sound when they hit

They shouldn't......if the ones you heard were "popping", then either there was a box problem, the subs were bottoming out or the coils were leaving the gap.

once they bottom out from a leaky box, or too much power or whatever, it doesnt take as much for them to bottom out the next time.....they sounded great but i had to let em go, and thats why

a leaky box can bottom out your sub and cause a popping sound? how about to small of a ported box for a particular sub?

dude your gain is way up. on my bros kicker amp i have it on 4 and he has a 2volt h/u.

I would say that the gain is too high or you have a sub hooked up below the amp's rated impedance level.
