i always listen to songs or watch movies on my computer. just recently some one gave me a nad c326bee amplifier . i bought these old onkyo thx certified hts f2 front speakers and hooked them to the amp. after i play 4 or 5 songs the cabinet of the amp starts heating up . it get very hot. i asked the person who gave me the amp if the amp got heated at his place but he said no . he said may be the speakers are not matching. im just a novice. the amp i think is rated for 8 ohms and 4 ohms while the speakers are 6 ohms. is the amp heating up during use because the speakers are not matching. i searched the net and got the spec sheet of the speaker which is in german language . attaching it to this tread. pls help.
It seems that we have to ask people to figure out their power need first every time they ask questions like this.
Truthfully it is not possible to give you an answer without knowing your power need first.
Your power need depends mainly on:
1) distance from your listening position to the speakers.
2) sensitivity of the speaker
3) impedance of the speaker
4) your spl requirement
You have provided the information we need for 2) and 3) but not 1) and 4. Or you can use an online calculators such as the two below I just linked in another thread.
Peak SPL Calculator (homestead.com)

Once you got that figure out, you will get the answer as you already know the C326BEE is just a nice little integrated amp rated for 50 W into 4 Ohms but obviously more on short term basis.
Another thing to consider is, when you say "heating up", what exactly do you mean, and how much space have you provided the amp to vent?
It would be helpful if you post the temperature measured on the hottest spot on the enclosure after playing your favorite music for 5, 10 and 30 minutes, just an example.
