Clipping = ?

[AVSTANG02]

It was fine for 15 minutes then you came out of work it was clipping?

can you elaborate more on this...

to my understanding speakers fail in 2 ways.

1:mechanical failure.

2:thermal failure.

under powering a speaker will never kill a speaker! nether mechanically or thermally.

overpowering a speaker will kill the speaker! ether mechanically or thermally.

a too high of an input signal, will create a clipped sine wave as the output. meaning what was supposed to be a sine waves now has a valley. this valley could be at 35 to -35 volts DC most low power amps or 75 to-75 volts DC on higher power amps, why does this kill the subs?

because speakers are not design to handle DC. DC will over heat a voice coil in a matter of seconds.

that's why is so important to adjust your gain properly. don't think you can get more from an amp by just increasing the gain settings. this is how most amps fail to create a clean audio signal and one of the most common ways of killing a speaker.

PS: it is possible to kill a speaker with 50watt amp! if you push it to clip the output signal.

X2.

How did you know it was clipping??

When I hooked everything up, I went to work because I ran out of time. On my drive to work (15 minutes...) everything worked fine.

When I came out 5 hours later to drive home, I turned on the car, and the speakers sounded like a constant fart (which to my understanding is the sound when its clipped?).

I have taken my gain all the way down, and it still is doing that noise, maybe its not clippage that I am hearing?

maybe the speakers are out of phase. they tend to sound like fart when you have wired one sub inverted from the other.

check your wires for the subs on the amp + and - .

invert one of the speaker wires and there should be a sound difference, i hope it helps

yea? when i had my subs outa phase, it was just quieter.

I would like a suggestions from you, almighty.

Seriously, that is not sarcasm.

what else do you need to know? if the speaker was blown from the clipped signal, then this thread would be titled "sub death from clipped signal". i don't understand what else is necessary

I would like to know why my speaker sounds like an ******* and not a speaker, I adjusted my gain, and HU, and still it does not solve the problem. Could it possibly be that the speaker is in fact out of phase?

what do u mean it sounds like an "*******". that gives no information. that could mean its not as loud, or that it is distorting. if it indeed isn't as loud then it IS possible that you have them wired incorrectly. BUT, since it just happened, i doubt u ripped out ur setup and switched your wiring during your lunch break //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

so how are his speakers blown? sub just don't die from sitting there! with no power applied to them. if you have a multimeter check the voice coils for conductivity and or resistance. that should tell you if the subs voice coils are blown or not, " they could still be blown if the glue got burned of inside the sub" then check all your wiring from amp to subs and power. if every thing is nice and tight. power the system and look at your subs go, if they don't bet to the same direction then your subs are out of phase. reverse the polarity of one of the subs wires.

Do you ever read prior posts? I said it sounds like it is farting, not distorted, just like a flapping sound. Is this clipping, or something else...?

Jesus Christ, I never said they ARE blown... I asked if it could blow a speaker. And it is only one speaker.

What voltage do you have going to the driver...
