possible blown speaker

[chawski 10+ year member]

hey guys, quick question. I have a AVIC d2 that a while ago was causing alternator whine through the front rca's and long story short, just ditched the 4channel amp and powered the speakers off the hu. All was great for a while. Recently noticed the same whine coming out of my front left speaker/tweeter only. all other speakers sound fine.

My question is: Could a blown speaker or tweeter cause the system to try to ground through it, causing this whine? Seeing as its coming from only one corner of the car and not all of them, i dont imagine its a head unit problem. I know the whine is a common thing with the avic d2 (believe me, been though it plenty) but that is due to the rca's, and since im not even using them, im a bit confused at what might be causing the alternator whine though only one speaker

Thanks!

are you sure its alt wine, it almost sounds like it could be a problem with the crossover if its a comp set or the speaker itself,

and if it was a ground problem you would probably hear it in more than one speaker, and some HU's will go into protect if one of the speakers is grounding

Im not certain at all that it is alt whine, but it is a very similar noise that i had when i had the rca problems when i bypassed the amp the last time this happened. Being that its only one speaker having the problem, I dont imagine its a ground issue, as that should affect all the speakers. Considering how cheap a crossover can be built, i think im gonna make a new one and see if that fixes this.

Also, I noticed today that the output on that corner doesnt sound as loud when compared to the passenger side door. think that could be directly related to the crossover?
