12w6v2 amp

actually that was my audiobahn 8001d firing my w3'sv1 (very well). but the 501bd drove my jbl's insane. w/age comes memory loss. ask around though.

it is often times hindering to understate another's point. further, it would bennefit us all to quote beyond forums, as if one were to quote yourself on this forum, he would be poorly informed. with all respect due.

this is a quote from "basic" car audio and electronics:

http://www.bcae1.com/2ltlpwr.htm

If a relatively low powered amplifier is driven into clipping (to a full square wave for a lot of people), a relatively large portion of the time, the voltage delivered to the voice coil no longer resembles a sine wave as it would with an unclipped signal. While the amplifier's output is clipped, the voice coil is not being motivated to move as far as it should for the power that's being delivered to it and therefore is likely not being cooled sufficiently.

It always amazes me when I hear some idiot driving down the road and the audio is clearly distorted (is that possible . Many people drive their amplifiers into what could be called a square wave output (white line below). When an amplifier is pushed that hard, it is actually possible to drive the speaker with twice as much power as the amplifier can cleanly produce into the speaker. This means that the power is double but the cooling of the voice coil will not increase in proportion with the power increase (since the voice coil isn't moving as much as it needs to be for the given power dissipation). This will lead to the voice coil overheating.

If we compared the output of a 100 watt amp (the one that's clipping) to a 200 watt amp, the 200 watt amplifier would be able to push the speaker as much as 40% farther than the 100 watt amp (depending on the frequency of the signal). This extra travel (in each direction from its point of rest) would result in added airflow around the voice coil.

Point=> give your subs insufficient power=clipping=distortion=bad

give your subs more than adequate power=clean signal=good

A three page thread for choosing an amp //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif

technecally if you sum it up with cause and effect you are both right to a degree of probably 90% but on one of jmac's examples about burning a disc with distortion on a technical level lol is it still distortion? lmao

On my 12w6v2 i had a fosgate 500bd or 501bd whatever that thing is, and it worked fantastically

How isn't it distortion ?

I'm guessing because it is the original source material //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif As long as the amp (and subsequently speakers) properly reproduced it, it simply would be the source material.

lol correct and yes it was retarded but technically correct lol

Kinda like the distortion peddle on an electric guitar. You press the peddle, and it distorts the signal coming from the guitar. But burn that same thing on a CD and play it in your stereo, and it isn't distortion, it's simply the source material.

I dunno....I'm not going to argue an inconsequential point such as this though...LOL. Call it whatever you want //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I really don't see where this conversation came from, but let me summarize.

1. Distortion doesn't kill speakers. I have an amp with an average of 5% THD...I know this.

2.

give your subs insufficient power=clipping=distortion=bad

is wrong in its entireity (sp). Giving your drivers insufficient power is just that...you can send 15 watts RMS to something and as long as the gains are set right, it doesn't matter if the driver is rated to 100 watts. Again - anyone wanting to debate this point can listen to my 2 watts @ 5% THD and note how the speakers don't blow. Clipping is different than low power. What does happen is that people that don't know any better try to get every last ounce of power from their amp and push it past its limits - that will kill speakers.3. I like cheese.
