under powering subs

You seriously responded to my OBVIOUS sarcastic joke with a lesson in thermal failure points of coils? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

I miss the cotjones of old //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

The answer is YES. That is why I have to buy a new set of subs every time I turn it down to talk to someone and they are only getting 100 watts each instead of the 1500 I usually have to each.

Duh the answer is no. I could run my subs on 100 watts for weeks straight and they wouldn't blow.

Edit: If the question is can i blow a sub by turning my gain full h/u full and tossing in some bass boost while playing 27hz tones on a box tuned to 50 maybe is the question?

x2! Now he's on a strong mission to prove how smart he is. Can we have the old cot back? Italian racing chips and all..?

From BCAE:

* If your speakers are capable of handling significantly more than your amplifier can produce, driving them with a clipped signal will not likely hurt them.

* If the speakers can handle 3 or 4 times the power that your amplifier can produce, there's virtually no way to damage your speakers (no matter how clipped the signal is).

* If your speakers are rated for the same power handling as your amplifier is capable of producing cleanly, driving them with a clipped signal for extended periods of time may cause speaker damage and/or premature failure.

* If your speakers are rated for the same power handling as your amplifier is capable of producing cleanly, driving them with a square wave signal for extended periods of time will likely cause speaker damage.

Well, if he can explain to me the reason the resistance of copper increases with increased heat I will be impressed.

Ok ok. With answer being no, you can blow your subs by turning up bass boost, cranking the gain or turning bass up on you h/u too much. This will lead to a clipped signal. A badly clipped signal can blow a sub on less than it's rated power handling because it requires a sub to basically do something it is not meant to.

better. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thank you //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I wish I knew this when I first got my Q. It might not have blown. Eh, oh well.

Simple.

the latice of atoms in the given element are able to allow for the transfer of electrons less as the element heats up because the increased vibration and collision of atoms associated with increased temperature, lessen the ease of electron flow.

think of it like this, It's easier to swim across a calm pond than a rushing river.

The energy of the water molecules flowing against my motion in a certain direction counteract my motion.

Well In a copper wire for instance the heat doesn't cause the atoms to bombard the electrons in one simple direction as in the river, but in all directions, lessening the over-all flow, resulting in what amounts to increased resistance.

honestly though, this is 9th grade physical science, you've all learned this before, I hope.

Wow, he was actually correct, I am impressed.

Now tell me what those lattice vibrations are called for extra credit.

Who here thinks that the cotjones of old is not the cotjones posting now? Hey imposter..how do you feel about mixing different JL subs..?

Will a flux capacitor power my prius?

Naw, he just learned what Wikipedia is.

ummm not sure, you'd have to be more specific.

If you are talking strictly about positive ionic lattices in conductive metals i'd call it thermal atomic motion. but you are probably looking for a more specific labeled answer.

I'm not good with memorizing theories and labels, just at understanding concepts and how things mechanically work.

They are called phonons.
