to somewhat answer your question, a 1200 watt sub can still blow from only 400 watts(seriously thats about what your amp makes, sry dude), IF the amp is sending distortion to the sub.

you really must of been pounding on that sub for it too blow, the infinity sub is a nice sub, and takes a pounding too.

 

do you have loudness or any other "sound enhanching feature" turned on

yes, there is some bass boost or something like that. that would suck if that was all it was :/

but how do i fix this "sending distortion" if it is doing that? cause i cant tell :/

 

Think of it this way. Your car has a redline, so does your amp. Take your vehicles engine above redline on a continous basis, bad things are going to happen, do this to a sub and the same bad things are going to happen. A sub must be allowed to cool down, thus playing something at a sustained volume level for most subs without allowing them to cool is going to cook them but good.

A sub reproduces what it is given, if it is playing distortion, it is being given distortion. This may be from having the bass control cranked on the headunit, having a bass boost engaged on an amp, a real crappy recording on the cd, a crappy amp that is not producing what it says and has been improperly set up..... these are just some of the reasons for a sub to start having issues. You need to learn how to use your stereo properly and work within the limits that it has. You do not have a big amp, do not expect big monster pounding bass.

 

well now your just starting to annoy me MR2NR, you dont need to be talkin like that...

first of all, before that sub blew, (during those 5 minutes) that was THE loudest sub i have ever heard...now dont get me wrong, ive only heard a couple handfulls, and none by guys in competition etc, just daily drivers...but honestly it was absolutely sick...i couldnt see out of my rear view mirror at all, cause it was shaking so bad, i felt it all the way up through the floorboards and was shakin my feet, i could feel it so much through my seat that i think it moved my bowels... now that being said... im going to go buy 1 or 2 more of these things, and hopefully take it to someone who knows how to &^*$ing set my amp correct so that it will last longer lol...

anywho, how come you didnt reply to the audiobahn's dual 2 ohm setup? at least admit when you might have made a mistake, instead of just hoping it will slide away. i hate when someone gives me wrong info about something and never clears it up. anyways, thanx for you helpp previous to this post, i appreciate it..

and if anyone really knows how to set the gain etc on my amp, let me know..otherwise i might have to leave it in the hands of best buy or futureshop :/

 

do a search on seting gains, you cant fix distortion unless you turn down the volume. distortion usually comes with clipping, and clipping is what your amp does when its at its max power, you cant fix it.

 

Actually, I was aiding a customer who came in the store. It was an oversight on my part to see the sub as a dual 4 ohm and not the dual 2 ohm that it is.(as this sub is a 03 model, I had to do some searching for the info). Thus this sub will work for you if it is wired in a series / parallel configuration. So was I flawed in my memory of the voice coil arrangement of that sub, yes, and I can own up to it as well with out letting it slide unanswered. FYI, I too have a customer with that very sub that it will not be warrantied by the manufacturer. My advice, steer clear of it.

No offense dude, but if you blew a sub in 5 minutes, then something was horribly wrong. Either bad sub, bad match of box to sub, improper setting of gains or just plain old abuse. You are going to continue on this path until you learn how to use the system properly and ensure that it is matched together properly. If you have a V8 mustang and do the Pilsbury tire bake off at every light, next thing you know the tires are bald. Who's fault is it, the tires for having crappy tire compound or your heavy foot? The same thing goes for a sub, it will reproduce what it is given. Feed it distortion, it will play it until it fails.

Since no one really answered this question, I'd just like to say that no, any old box will not do. Regardless of whether or not you plan on competing, box size will have a HUGE impact on the performance of your system.

I would say that your Infinity blew because you had too much power going to it, or because your gain was set too high and your signal was distorted. Of course, bass boost and loudness can also cause harmful distortion. But even if your amp doesn't really make 800 watts, it still may have been too much for that sub, especially if you're inexperienced and don't really know your system's limits. I would definitely recommend getting a sub with higher power handling, and build the box to spec. Also, give the store hell for setting up your system to blow in 5 minutes...

 

Probably the ported box is the cause of your grief.
Any notes below the tuned frequency sent to the sub, will cause serious damage....the mechanical power handling drops way down at frequencies below the port tuning. so even tho it's a 300 watt RMS sub, it probably only can take 50 to 100 watts in that box at 20hz.
You need to have a sub-sonic filter if you use a ported box.

 

car trek, your reasoning sounds the best to me, and makes themost sense...

thank you...

 

anywho, none of this really matters now, because last night i had all of my gear stolen...my deck my amp my box and my blow sub :/ the blown sub isnt that bad lol..

theives suck.
