blew my HD315

[jmanjr]

lol hopefully your not serious dude, it will never work!! You have to glue the spiders in, and glue the foam surrond to the basket, then glue the dust cap on, obsiously after you have shimmed it properly so its tight!!

lol, naw, im clownin. I contacted an old buddy of mine from high school who is into car audio and he said he will help me recone and he has clue i can use.

i thought dd/aq used special glue? Maybe i'm wrong.

Can't you use that high strength epoxy?

Yes I really do. To be honest, I'm suprised that amp was able to blow an HD3 with a clipped signal.

X2 and I had 3 Orions at 1 time //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I ran mine fully clipped for a burp one time for $hits N giggles and didnt do anything to my 10 hd3 but not for daily driving. It just sounds like a users error thats all. BTW, the Orion should be set at 50VAC for 1 ohm nominal //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Its a tad under clipping at least it was for my enclosures. The orions seemed to clip at and around 69VAC for 1ohm nominal in my application.

You rate it approximately. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif It is how 90% of the people on here set their gains.
Using the O-scope is not an option for people who don't have access to one. I use the o-scope and a volt meter and the approximation on the volt meter has been correct with clipping every time, it is usually under clipping level.

Approximately is the key word in the statement you just made. Think about this: He has a Brutus amp. I have NEVER tested a Brutus amp that made it's rated power at it's rated % distortion level. On an Audio Precision test bench the Brutus amps are typically 15% over rated at 1% distortion and 14.4 volts, which drops that amp down to approx 1700 watts. The OP stated that he did not have a sufficient electrical system, so you know the amp is not seeing 14.4 volts. Probably more like 11 volts. If the voltage drop was bad enough to drop to 11 volts, the output of the amp would theoretically drop to around 1200 watts from the 1700 watts. So if you apply your DMM gain setting theory you would normally shoot for 44.7 AC volts for a 2000 watt amp, but in this application it is likely that 1% distortion will be reached at 34.6 AC volts. Attempting to reach 44.7 volts will result in a highly clipped signal. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You do have a good point there, which is why I set my gains with an o-scope.

But, if you are going to discount the DMM method you need to put forth a new method that people can do. I say this because unless you know a good place to get used equipment you are going to have to drop a good chunk of change to get an o-scope. I have one because I work in the audio/communications field, but most people don't and cant afford one that is accurate anyway...

I disagree. I don't NEED to do anything. He attempted to run 2X the manufacturer's rated power handling to the sub. Obviously it didn't work, although I can/have run 4X the rated power handleing to the same sub for daily use, and have never had a single failure. I suggested he use an oscilloscope, which IMO is the only proper way to set the gain. If he doesn't have access to one, that is not my problem. He should stick to the manufacturer's recommendation of a 1000 watt amp if he can't set the gain without clipping the amp. Again, not trying to be an a prick, but the manufacturer's ratings are set where they are for a reason. Running 2X the rated power to the sub, and complaining about a failure with improperly set gains is not reason for me to come up with a gain setting method for poor bastages. They should run rated power, or deal with having to buy a recone because they screwed up.

i love how Jeremiah is getting sooo defensive for AQ even though noone is bashing them. Yes i ran the HD3 at twice what the factory reccamends, Yes it can take even more then that. im not bashing them so you can stop ****** AQs pecker. We all know, for the second time of you telling us, that you arnt trying to be a prick, but you sure as hell sound like one.

I appreciate your knowlege of CA, i really do and i have learned a lot just from reading your posts in this thread but you really sound like a fanboy trying to stick up for AQ like we are bashing them. noone is saying anything negative about AQ.

Yes, im a noob, Yes it was my fault it blew. No need to rant on about AQs factory specs.

just my 2 cents, nothing personal....
