ohms...

[GuitarVman]

Novice question...

What would happen to a reciever that is rated for 8 ohm speakers if you connect 4 ohm speakers to it? Is it a bad thing?

Thanks...

a reflected signal ?

The worst-case would be that the amplifier burnt out. Next-worse: a

protection circuit kicked in and turned the sound off. Probably it
would function normally, maybe even play a little louder if there was
current to spare in the main amplifier. If the amp. was designed to a
price, maybe it would run out of power and give weak or distorted
sound.

So stick to the correct ohms for the reciever...

Thanks for the input.

shouldnt two 4 ohm speakers in series give an 8 ohm load?

snip-

Check the specs of the receiver. 8 ohms is typical to speakers found
in the home; 4 ohm speakers are found in cars. Many home receivers
are designed to drive two pairs of speakers at once, for a total
impedance of 4 ohms per channel.

The specs tell it all.

My amp is rated at 500 watts RMS per channel into 8 ohms and 1,000
watts into 6 ohms down to 2 ohms (presumably, at 2 ohms the protection
kicks in or smoke comes out). So if I want the full 1KW per channel
my speakers have to be 6 ohms or less.

If I used the full 1KW I'd be deaf, and the impedance would be moot,
so I don't go there.
