What happens if wrong ohms speaker works in amplifier

[surajts]

What happens if an amp with 3 ohms connect with a speaker with 8 ohms?
Will it damage speaker or amplifier?

The amp will heat up faster and if made of cheap components...it will blow....

Technically speakers with same impedance or higher are connected to the amp....

All this information is available over google....

The speaker will suck more current from the amp at loud levels and crap out the amp or go into protection mode. What amp were you asking it for?

Thank you

I think the amp capable of handling 3 Ohm load will not have problem handling 8 Ohm speakers.

The amp would struggle if it was intended for 8 Ohm load but the speaker was actually 3-4 Ohm.

Thanks jls001
I too heard like that and we cannot get max out put if impedance is more right?

Assume an amp is rated as 100W @8 Ohms. Depending on how robustly designed is the power supply, it could produce upto double the power (200W) at half the impedance of 4 Ohm. And perhaps even 400W at 2 Ohms.

Now do backward calculation for, say 16 Ohms load.

A lower impedance amp should be okay playing a higher impedance speaker. So a 3 ohm amp can play an 8 Ohm speaker without killing itself. However, How well it can play is the question. On the other hand, an amp designed for 8 ohm speakers if connected to a 3 ohm speaker can kill itself.
