Testing speakers with a Milti Meter
If it is MP3, have you tried to convert it to wave and burn a CD? See if you can reduce the recording level so that it does not hit the dynamic range limits.
Unless the particular track has a very specific tone that sets off some sort of resonance and distortion it would be very odd indeed if it was not distortion on the source.
try to trouble shoot
Is the distortion from both L and R? Is it in the rear also?
What if you reverse the L-R connections and play the same part of the song on the other channel. Or if you can switch the tweeters around.
Or on the rear speakers if you have them.
Have you tried playing the source back on a home system? etc..
All cd decks have some sort of error detection and correction and may not be the same. Some are better than others. Even mp3 players have some sort of error detection setting or other smarts that prevent gross overloads or junk data from hitting the DACs.
It's the same with original cd's or mp3's. Seems to be only in the left tweeter, But it depends on the mixing of the albums.
I have a tone cd burnt right now and I plan on trying it later, And I will have an amp hooked up very soon too.
If the tweeter is blown I can order 1 tweeter for $100 from Morel, Which is not too bad. Easy to install, I can just take it out snip the wire and use some butt-connectors.

But what do you mean by mixing of the albums? tweeters dont remember the order you play songs in and behave differently!
The playback errors can be only on one channel!
Well I think I just determined that the left tweeter is damaged.
I played a tone test cd and on high frequencies the left tweeter will have a hissing sound to it, And when i fade to the right channel I don't hear the same hissing sound.
It seems to be at certain volume levels when you can tell that the tweeter is damaged.
Just like in some songs, When I turn up the volume a certain amount you can hear the left tweeter distort.
Basically it's partially blown, Which means a blown speaker to me anyhow.
I will replace it in the future!

"hissing" sound? "Hiss" is noise. Good or bad speakers don't generate noise. Amps generate noise. Are you sure? switch the left and right! are you using an amp? switch the RCAs from HU to amp and see if you have same problem. Then switch speaker connections from the amp and test again.
No amp at the moment, Only running off my Eclipse CD5030.
It only makes this noise at certain volume levels in the left tweeter, The right tweeter has no odd sounds.
I will test it again once I get my new amp installed soon.

Good news, After having my amp installed and moving the crossovers to the trunk I no longer get a whining/hissing noise from the tweeter
.
I think it was the shitty stock wire, Or the crossover being in the door.

Blown tweeter.
If your tweeters are filtered by a passive crossover then the crackling could be caused by broken/cold solder joints. Access the crossover and check the solder side for corrupted solder and resolder where necessary. Also check the leads from all capacitors for breakage. You an resolder the lead or if space is tight hardwie the sucker to the board.
If an active crossover is used check the crossover point. These small dome tweeters typically operate from 2.3 khz. and up, and tend to break up easily when the crossver point is set too low.
If they are piezo tweeters just replace them.
All of the above should be explored once you have determined that the source is aok.

One thing I did notice after having my amp install is a constant hiss in my components, It's the same level no matter how high or low I turn up the volume.
I adjusted the gain, No help. I am wondering if it is the stereo's ground. Maybe I should ground it to the chassis. The amp is grounded in the back on a bolt that has been sanded down.
I have good quality RCA's and wire, So maybe both grounds should be on the chassis instead of 1 ground being on the chassis and the other being on the factory wire harness?
