head unit overheating?

so i had my head unit pulled out today and i noticed on the back of it there is some sort of a block of aluminum, im pretty sure its a heat sink but there arnt any fins on it. anyway i noticed it was getting very, i couldnt touch it for more than about 5 sec before i had to take my finger off. is this normal? the HU is a sony xplod cdx-f7715x. iv had it for about 2 years and it has always work great.

They get hot - 5 seconds is probably the norm, but it's been a while since I tested one Is everything sounding ok and not cutting out?

My deck makes cd's hot to the touch with the internal amplifier turned off.
Been doing that since I bought it over a year ago and no problems yet.

But if your really worried you could install a computer fan in your dash to cirrcuate air across the heat sink.

If it's not cutting out and SQ is fine then you should be ok as said above.. another thing to note is if you run alot of CD-R and CD-RW decks will get hotter too...

I had noticed my faceplate was getting toasty when I pulled it off once, but I think its from the internal amp.

Now since none of the speakers are being powered by the deck, and the internal amp shut off, I haven't really noticed the faceplate being hot as hell when i take it off..

so I guess amping has to help that, but whatever, if nothing is wrong, then you shouldn't be worried about it.
