i definatly think it is that u r not breaking it in and just running it to hard the hole moisture thing i agree that guy is an idiot and no if u listen to it for long periods of time then it will breakin in like a week but if u r not listening to it that much during the day say for like 15-20 min it takes a long time as for over power not a chance 500w there is no way like i said before thats perfect or even a little underpowered but never run ur gain at 100% thats both not good for the sub or the amp and and they have no choice but to warnty that sub because it is there job just as it is my job to give u all this information in the first place and because they did not do that they are obligated to give u a new sub in my opinion u did not now and they sould have told u when u baught the equipment from them (by the way i didnt take offence but i do no what i m talking about)

yeah well i do listen to it alot so like 2-4 weeks would probly be a good break in, also id never have my gain up 100% it would get distorted and rattle too much, hate rattles ugh, yeah they should get me a new one if i dont have the same guy i talked to today

So you have lets say a 3volt output on your cd player and you cranked the gains. This means that you took the amp way past it's ability to produce clean power at 100% or rated clean output and ran it into clipping which throws even more power into the sub. You overpowered it. If the thing smells bad and the cone is going scratchy scratch scratch when you push on it or it jsut pushes in and stays in, the coils are going to be cooked blacker than a steak left overnight on a barbeque. You can blow a sub only one way, take it past it's thermal abilities by overpowering it. Do you think your amp just magically stops producing power when it hits 500watts? Guess again. Learn how to set your gain properly and why it is important to. If you are thinking that hey, I crank it up and it gets louder, be prepared to blow another speaker. Want louder, add a second sub and change to a bigger amp. You might also gain some output from a different sub box.

mr2nr, no where on this thread have i said i cranked the gain 90% of the time its at 50% thats not cranking it, if anything at all i would be underpowering by a little bit

alpine_focus

ill put it in terms that u will understand as an inexperianced consumer he is right in a sence but what u did is ran it to hard while it couldnt handle it and yes it caused the sub to clip and be overpowered in a sence but it is not because the amp is to powerfull u pushed the sub more then it could handle without breaking it in proper and it over heated again the salesman sould have told u this to begin with and u wouldnt have this issue

alpine you are going about that in a good way not just pointing finger at consumer, but the sales person aswell. I will be quite honest though I have never had a sub that took more then a weekend to have rippin. ANY sub can be pushed without failure, I ran some bassworx subs on 3000rms daily and hammering them all the time. never a problem, but there is always that chance it could happen... BUT there is no excuse for that sales mens idiotic reply to it.
Rob you know your , and ya it might have been over pushed, but seriousely a type R with a month breaking in, should be able to take the amps power. I not super smart with boxes, does that box check out? You know aswell as I do that a box can kill a sub quicker then anything!

The box is more of a mechanical failure type of issue for a sub. Heat is what kills subs in all cases that are not mechanical. There is only one way to get too much heat. That is too much power. Unfortunately too much power does not discriminate on ANY brand or model of sub. All subs have their thermal limits and if you take it past it, it may cook on the spot (thus the escape of magic smoke) but more probable is the long downward spiral until one day it just refuses to play or sounds like a rattle can of angry bees.

Heat is a natural byproct of the production of power, you cannot get rid of it. If a sub is played too long at a sustained level (even below full rated output) and the sub cannot keep below the thermal barrier, you are going to blow your sub. Volume at 90%, a little extra level on the sub out even with the gain at 50% (which still could be set wrong) and sustained output = a recipe for disaster more many subwoofers. OP, the goal here it to help you understand what is going on with your system to keep it from happening again. Not trying to pull the wool over your eyes or anything like that. If you want a little experiment here, push on the cone of the sub and see what it does, let us know as well. A really good experiment would be for you to cut the speaker out of the basket and look at the coils yourself. My bet is that they are blacker than black black is black.

actually the position of the gain switch is not the issue, the issue is when does the amp put out full power when matched with your HU. if it maxs output with the gain at 50% then any movement of the gain switch between 50 to 100% is inconsequential it is still putting out full power. If it sounds distorted, then it is distorted and turn the gain down. Personally I try to balance the HF/ Midrange and Sub-bass and that keeps my system in a safe condition for day to day use. If you do your homework you can turn it up to show off and not release the magic smoke.

Here is the big question; if you blew one sub and you are given a new sub, what are you going to do differently so it doesn't happen again?
