Tweeter Blowout
Hey guys,
So I switched out my crappy stock speakers in my evo for alpine units all around, including an alpine headunit. Everything was good for a while, all of a sudden the passenger side tweeter blew out, now im 27 years old, I dont listen to my music like a 18 year old kid, I merely switched the speakers cause the last idiot blew out most of the stock. So I thought wow that sucks, order another set of alpine type R tweeters, not cheap but eh, installed, works great. A couple more weeks go by and duth my ears deceive me??? This one blows out too, wtf??? All the other speakers work great, just this one side, two different vendors. Is this possibly a wiring issue? its seeming less like a component issue and more like something power/wire related.....

Not at all, i apprecoate you trying to help. No crossover, just in the stock IX location, I tried adding a crossover on the original installation but I guess it was filter too much, you could barely hear the sound coming out of it and it was super high pitched

You're blowing the Alpine tweeters, because they're running full-range. Meaning, they're trying to reproduce frequencies they can't handle, producing excess heat, in turn resulting in catastrophic failure. Did the Type-Rs come with a crossover, or did you buy the drivers secondhand? Am I understanding that all the drivers (tweeters and mids) are now running without a crossover?
No. Just no. This is pretty much impossible, save for a setup where the drivers are (essentially) perfectly matched, facing each other with little distance between them, and a demand for high amplitude. FWIW, tweeters in mobile installations are typically wired out of phase with each other, as they are in the stock setup.

The stock tweeters are already limited in their extension, so adding another crossover would result in the response you're descending, if I'm understanding this correctly.

Sadly these don't look like very high tech crossovers, just look like two bundles of copper wire with wires coming out of them. I dunno....I need to consult someone really good with audio, all I know is go fast guys

I have the crossovers, all drivers are running without a crossover, like I said when I put a crossover in the sound for the tweeter got very very high and you could barely hear it, I would agree with you about the tweeter trying to display the full spectrum of sound but why hasn't the other one blown out? Just this one twice....Also neither tweeter is showing any sign of strain, feedback, clipping, phasing, etc they sound great. I just don't get it...
trying to play bass on a tweeter will blow it.

The Type R components come with a cross over. You are supposed to run a full range signal (the radio signal to the lower door speaker) to the cross over, and then split it to the mid-bass speaker and the tweeter..
you also might have an impedance issue going on there, but I don't know the specs of the factory tweeter/type R tweeter in front of me.
