RE: It's not the watts, it's current....

Posted by Rod M on August 6, 2020 at 09:08:36:
I understand the math and in a perfect world, yes, an amp should double the power or watts in going from an 8 ohm to a 4 ohm load and double again into 2 ohms.

For example, the specs for a Yamaha A-S801 reads like this:

Watts RMS per Channel (8-ohms) 100
Watts RMS per Channel (6-ohms) 120
Watts RMS per Channel (4-ohms) Not given

So, how do you explain the fact that many amps can not handle lower impedance loads?
