Okay, So around christmas time I bought 2 3-way coax 6.5s and 2 3-way coax 6x9s from Pioneer, a few nights ago I noticed at moderate to high bass there was a loud annoying and painful sounding crunching or cracking sound.
So I thought it might be my headunit. Pioneer DEH-P4700MP
it puts out 50Wx4
The Max Wattage on my 6.5s was 180W, recommended was 55
The Max Wattage on my 6x9s was 220W, recommended was 60
So I went back to the stereo store, I'd bought the HU from a friend of mine and he just exchanged my head unit for a new one, just like that, unfortunately, that wasn't the problem.
He came out to my car and tested my problem, he said that all of my tweeters were blown, which sounds about right, sounds like they're just rattling like hell when they have to put out any sort of midbass.
I'm going to try to claim warrantee, since I've never used anything but pioneer.
Is there anything else that this could be? Faulty wiring, etc?
Any idea why they'd all just, GO? At the same time? When not exposed to any abuse.
my guess is that a signal in their high range messed them up... as you said, all went at once... so either the signal was processed and sent out right and the faulty signal was from whatever you were playing a the time, or something happened within teh deck itself for it to change the given signal into the "bad" one that blew out your tweeters... that is teh only thing I can think of...
also, as a general question... I didn't think tweeters were made to carry midbass... is this true or am I just clear out of my mind?
Tweeters can't handle any midbass at all. Sounds like something is wrong with the wiring, because if they're crackling when midbass is played, that means they're getting those freqencies, which they shouldn't because playing that low will blow them. Sounds as if the tweeters are crossed over to low.

So is it too late, or do you think there's anything I can do to correct this?
If the speakers are blown, they're blown. You'll have to replace them.
It sounds to me as if the problem was caused by improper crossover settings. Did you wire the tweeters directly in line with the drivers, or was there a crossover or resistor in line?

these are coaxial, as in one pre-assembled.....assembly.
All I had to do was hook up + and - from the stereo.
so you are not using components ? Strange how you blew the coax then....

I give up...
i'm buying a VW those people love trees, so they should love eachother too... "Andy"
I don't know why anyone would have 4 sets of components
does your HU have High Pass Filters? If so you should use them,and not try to put and fq below 80 or so to your mids and highs. If not atleast use BASS BLOCKERS, and if you do not have enough BASS, add a Sub.
What is wrong with 4 sets of components?
The Amp is faded to the front, the rears just help to be louder at car shows.
okay. looked at this for a while, it appears that it is lowrange bass, rather than midbass (HU has a 3 band equalizer and it doesn't crackle when midbass is boosted but does for lowrange.
So what are the chances I can get warrantee to cover it?
I will agree with sndsgood on what he said! Just because a speaker is rated at 150 watts, doesn't mean that sending it 50 watts is safe and you can just do whatever with em and they won't blow. When your headunit is rated at 50x4, what they really mean is its rated at 20x4rms, and a 50 watt peak signal of dirty ass distorted "clipping" that will fry a 180 watt rated speaker faster than sending it 200 watts of clean power. If your headunit has highpass filters for speaker outputs, USE THEM!! Thats what they are there for , to protect the speakers for @!#$ that they cannot play. If they don't then turn it down till you can afford an amp that has them.
