tweeter cuts out at loud volume

[blazeplacid 10+ year member]

but how could that be if the set is rated for more than what im giving it and the gain is all the way down???

im not doubting you ,im just trying to figure out whats going on

Because of the input signal.

I'm not taking it as you doubting me, I get where you are coming from.

There is only a certain amount that comes out clean (there are people who will really get technical but I'm just simplifying) for instance if you try yelling at a certain point you start to strain and the voice changes (your still getting louder but not the same results) electronics are much like this.

It isn't that your giving them too much power. It is that you are taking the headunit to the point where it can't keep the signal "clean". So the power it is producing, albeit more, is starting to straing and you are getting a clipped signal which damages the speakers (more than higher power in my opinion).

Here is the definition of clipping : Clipping is a form of waveform distortion that occurs when an amplifier is overdriven, which happens through attempts to increase the voltage or current beyond its threshold of power.

from here : http://en.wikipedia.org/wiki/Clipping_%28audio%29

Basically, you could turn down the head unit and turn up the amp and have louder speakers that would not cut out. You just need to set them up.

Why not just go try what was suggested already. Turn the gain up and stop turning the hu up.

If the HU's clipping then there's your problem.

I run all my alpines at 20-21

I'm not thinking that he won't try it, I think he is trying to understand why.

Honestly, if I was new to audio this would totally blow my mind as well (if the speakers can handle 100rms and he has an amp that is only 65rms that isn't even turned up on the gains, how can he have a problem) just seems like everything should be ok when in reality they are seeing a 45 watt clipped signal. The thing that isn't always known is that just because a HU will go up to 40 doesn't mean that it will actually play a clean signal at that level.

Because the clipped waveform has more area underneath it than the smaller unclipped waveform, the amplifier produces more power. This extra power can cause damage to any part of the loudspeaker, including the woofer, tweeter, or crossover, via overheating or overexcursion.

That is from wikipedia and should pretty much explain your situation.

allllright so i adjusted the gains up at volume 20 and that has cleared up my problem

thanks to you guys very much

glad to see someone getting some good help around here.

Glad to hear it!

Now just make sure your gains are set properly or you could still damage the speakers later on.
