I'm going to have to go with airspace on this one. if you where using this same setup in your car than it should have stayed the same, but the airspace. obviously you didn't use the same box to put under your seat. airspace can make a sub or break a sub. i used to do custom installs with a friend andi have found that it doesn't matter how big or small the speaker or how much power it gets. if you don't have the right amount of airspace it will either blow them or make them sound horrible. i had a 2200 watt 15 in my single cab in a box that was not the correct airspace and it was barely even noticeable. I built a box to specs and it shattered my rear view mirror.a lot of people think brand names and where you have your stuff installed is the problem, but they only do what YOU ask of them. and Ive heard pioneers from wal-mart win comps with the right boxes. so check the airspace of the sub, if you cant get enough from under the seat then get a different sub that only requires a small amount of air to operate correctly. good luck...

 

Well I have to disagree I have had a sony Xplod 10" sub in my 94 dodge ram singe cab for over 5 years and it rocks takes all the pinishment I can give it granted Sony subs are not the best but I was looking for the best I wanted a cheap system that sounded good!!

 

My oh my there is some absolutely frightening information here.

First, when I mention power ratings below I am speaking in RMS terms. Max power ratings are useless and do not mean anything. What you want to concern yourself with is the RMS power of an amplifier and the RMS power handling rating of your speaker.

There are only2 ways a speaker can fail. Thermal failure and mechanical failure. Thermal failure occurs from overheating the voice coil by sending it too much power. The glue holding the voice coil together fails and the coil either unwinds from the former or it shorts. Mechanical failure is caused by overexurting the speaker. Again, this is an issue caused by sending a speaker too much power. However, instead of the voice coil overheating you get the speaker moving too far and tear the suspension.

Thermal failure comes from exceeding the power limit of the speaker. Enclosure isn't really a factor. The enclosure can influance the cooling of the voice coilbut it is not a significant influance so you can ignore it. Ifthe voice coil burns you sent too much power to the speaker.Matching a 500w sub to a500w amp does not preventyou from being able to overpower a speaker. If your gain is sent incorrectly or you use any processing features that boost your signal, such as a bass boost, you will start to clip the signal. A fully clippedsignal has twice the power ofits unclipped state.Set your gain properly or have it set properly and then do not touch it. Do not use any bass boost, loudness feature, or any kind of equilizer with your subwoofer. If you do you will be immediately clipping your signal and sending more power than you intend.

Mechanical failure is enclosure dependant. The power handling rating of a speaker is its thermal rating. This means you can destroy a speaker rated for 500w with 300w by overexurting it.For sealed enclosures the smaller you go the more power you can send to a speaker because the less cone travel you willhave. The larger the sealed enclosure the more excursion you will have for a given power input.The lower the frequency the morethe cone will have to travel to achieve the same volume.For ported enclosures the same holds true but you also have to concern yourself with the tuning of the enclosure. At or above tuning ported enclosures have limited cone travel because this is where the port and speaker are most in phase. Above tuning you the port becomes less of a factor and your enclosure will start behaving like a sealed enclosure. However, under tuning output drops and excursion skyrockets. You will hear this referred to as unloading.You do not want to be playing frequencies too much under tuning withmuch power or you will overexurt your speaker.Most people employ a sub sonic filterat or slightly belowtheir tuning frequencyto help prevent problems. A subsonic filter is simply a crossover that allows you to filter out frequencies below a certain point.




It is pretty hard to diagnose what went wrong for you without checking things out in person. However, if you consider the above you should be able to starttroubleshooting things yourself and begin correcting your mistakes.

 

one question, did you change enclosures when you went to the truck, if so, the subs would need to break in again, and if pushed to hard to early, that could explain the detonation. being that the amp driving them was the same without changing its settings

 

Learn how to set your gain controls.

Amp clipping and distortion is death to speakers.

There is soooooooo much other wrong information in this thread that I don't even know where to start.....so I'm not even going to bother.

 

true lash, there is alot of miss info, but they intent well. distortion will kill a speaker faster than too much power. Hope all the contributions here can help you find your problem m8.

 

1st thing I'd do is replace those subs with something good. Like said Sony is just pure crap when it comes to car audio especially nowadays. They were okay pre xplod days. Seems like quite a few people that run Sony subs have issues blowing them.

Then I'd check and make sure they are wired properly with enough power to push them. Make sure you have your gains and all set correctly too.

 

I am not being a smartass...

You two seem confident in your audio abilities, please do post some info. We're all here to learn. Just give us the cliff notes.

For instance, i was always told airspace, is airspace. If you need 1 cu/ft, and you have 1 cu/ft, with wood or glass. it does not matter. But others here tell me i am wrong.

 

Incorrect.

Read my prior post. There are only two ways to damage a speaker and distortion is not one of them.

 

The medium you use to build an enclosure does not matter all that much. The person who brought up fiberglass was trying to say that you can get more airspace from a fiberglass enclosure than you can with a wood enclosure which is true.
