well, i was outside cleaning the car up a bit had my music going a little bit, not that loud though.. and when i got around to the driver side i noticed a little difference in the music.. so i closed my doors sat and listened, i realized not as much was coming from the passenger side, as far as highs, so i pulled the sail panel and noticed the tweet "appeared" to be fine, so i went and did the same to the driver side tweeter, i couldnt bare to touch it, it must have been 150º +.. but it was still playing music, so i went back to the passenger side and noticed its not, so i pulled the passenger side cross over and find that the plastic casing is melted, *the mids still played 100%*, so it seems the tweet must have been blown, for some time now and i just realized it, however i think the driver side is about to go as well because it is now getting fairly hot and the casing on the crossover is starting to melt just a little..:

oh and heres pics :D

and for those who have RSD components, you should know this hole, is not supposed to be here:

heres the inside of my melted (passenger) crossover:

the 2 white things just above the +2dB switch are VERY hot as well, this is what is melting the plastic on the crossover



now heres the driver side crossover:

as you can see, this one is beginning to melt, but not as bad as the other side is.

the white things above the switch are moderatly warm, not as bad though as the other side



im only putting about 80 rms to each side :confused:

the tweet is blown, i did confirm that, so the crossover isnt blown at all so now i just need new tweets for now until i can just buy a good pair of comps for up front

The white things are resistors. Musta shorted the crossover and/or tweeter.

only the tweeter, i hooked up my stock one to it and it worked so the tweeter is whats blown

oh yeah, and someone recommend me a pair of tweets, 1" that can get fairly loud and sound good off about 80rms, well 40, 80 to the crossover

its still getting 80 watts.

all the xover does is split what speaker gets what frequency.

:)

watch for clipping, it will heat them up like so....never seen one that bad though

I've heard of this happening before too.

my amp is rated @ 100 x 2 @ 4 ohms, but its over rated so i assumed around 80 or so but i know it shouldnt be doing that much :/ i backed off the gain so its only about 1/3 the way up compared to the 1/2 i had it at before

but what would be a good tweeter to get? ill just get a pair while im at it, still use the crossovers and mids, love the mids.. that wont run me a fortune, something that can sound loud, crisp, and clear.. i didnt really like these tweeters that much anyway..

water could have done it

I lost a tweet in the set as well. I bought the Memphis PR tweet to replace it. The tweet fits in the original PG tweet housing. I got them because they were cheap for me and I got a lifetime warranty.

Wow thats a heluva lotta tweets blown here..... I've suggested it before on other threads and I'll do the same here..... if you were to solder a dome light bulb in series on the positive lead to the tweeter you'll most likely save ur tweets from distruction.... Bose has been doing this for many years on their 801 and 901 series speakers and Polk Audio even uses this method to protect the tweets on their $800 SR6500 series components...... I put the bulbs on the tweets in my van after blowing a couple the first week they were installed and haven't had any trouble with them since.....

I've been asked before how they work..... dunno for sure, can't tell ya..... But they've saved mine now for over 2 years....... just my worthless .02 again......

The resistors are getting hot because there is more current going through them than they're designed for, I mean they're 5 watt resistors, ever touch a 5 watt night light bulb?? It's most likely caused by blowing the tweets/voice coils nearly being shorted.... I'd also imagine that clipping in the signal had alot to do with it as well..... another worthless .02.......
