Melted speaker?

[2pist]

Blaupunkt 5x8 voice coils melting tweeter post? I would think the coil would burn up before melting something. I measured the output for DC and it had .5v offset. It's a Chinese head unit with a (marked) TDA 75xx class AB chip. something strange going on here. Any ideas?

I had a boston reference 12" poly cone start to melt when a punch 150 had a failure. Sucked those subs and amp were the first high end car audio I had. They worked for 30+ years though.

Could this have happened in the summer heat?

Did the other one melt?

Nope. It does get pretty hot here so I considered that. I should mention, that is the 2nd speaker I put in the same door, did exactly the same thing. The drivers side has never had an issue.

Is it the way you park. Same side always facing the sun at work?

Did you try heating it with a blow-dryer to see of you could straighten it?
