Amp clips when cold?

[Dangrebel 89]

Ok so I've been noticing over the past few days that when my amp is like 30 degrees or les it clips when at half volume. It'll clip like that until the amp has about 5 min of playing then I can't get it to clip? So I think I have a temp sensitive amp. It's a bc2000d made by crescendo. Does anybody elses amps clip when cold?

I've been told that all amps need to be "Warmed Up" before maximum performance ... Could be just hear say, not sure ...

[Dangrebel 89]

Yea that's what I'm thinking, I just hope my amp is not weird haha

[Randal Johnson 544]

Don't tear it up before I get up there to demo it next month ...

Subs get real stiff when cold.

are you going to follow me to Lebanon and compete ??

Moisture?

That doesn't make sense, most if not all electronics run better up until a certain point, define clipping.

Are you going according to the clipinng light?

[Shogen 325]

^^I was gonna ask the same thing... I have a BC3500d and have no issues when I first get into my car, no clip light either but I did set gain low since I am weird and don't max gains ever...

[Julian 641]

Clipping lights = useless.

[Shogen 325]

Yes, but didn't know if that is what the OP was talking about...

[Jmac 24]

If you hook a DMM up to the amp when it's cold and play a sine wave, does the voltage change as it warms up ? If it doesn't change, it's a fault with the clipping light. Most amplifiers should have a consistent output voltage regardless of temperature (though the output impedance and, therefore, current should change).

Yes I was saying that avoiding to my clipping light, I know they aren't dead on but a certain amp level triggers them so it's doing something different then when it warm or it would pop on correct? Cablguy, I will try. Hopefully by then I will have my other bc2000d in. Gas money is the only thing holding me back.

Yep

lol... gas money???

[Dangrebel 89]

I get 9-10 miles a gallon

[Shogen 325]

shyt!wtf???

[Dangrebel 89]

Ha yea it sucks. That's why gas money is holding me back

As your subs get hotter, thier impednace increases and they draw less power for a given voltage...

The exact same thing i was about to say..

Clipping indicator, i believe, is solely triggered by AC voltage.

So.. if you REALLY wanna know what's goin on.. go out to your car when the temperature is negative hot, lol.. play a song until the clipping light just starts to become visible.

While song is playing, measure AC voltage at speaker terminals. Do not use peak, just watch it and remember the numbers u see on these bass lines.

Now.. wait for it to "warm up" and at same volume, do it again. See if the voltage has dropped.

Also, if i'm not mistaken, clipping lights are very accurate if using them to monitor test tones only.
