Wild guess would be 60w 8ohms. As the previous poster has mentioned, no such computation exists as the answer varies from one amplifier design to the next. Thanks all, including mhardy , for the explanation and the variables. I am driving Marantz Imperial 5Gs rated at 6 ohms and don't go for "loud" so I feel pretty safe with this Nikko TRM amp, I was more curious how it stacked up to other amps of the day in terms of output.
Messages: 6, Location: Timbuktu, Mali. If anything, a 6 ohm nominal load should be an easier to drive load than 4 ohm nominal. Some ifs - chip amps like lower impedance, the 6 ohm nominal speaker might have a nasty impedance curve that drops below even 4 ohms, stuff like that - but in general it's using speakers with lower nominal impedance than what the amp is rated for that causes trouble.

As others have pointed out, it isn't always the case that you will get twice the power at 4 Ohms that you can get at 8 Ohms you may run out of current first. But it is almost certain that you can get at least half as much at 8 Ohms as you get at 4 Ohms.
So the amp should be able to provide It might provide a bit more than TerryS , Feb 14, Messages: 38, Location: Central Missouri. Actually kinda weird that they rated it at 4 and not at 8. Usually it's the other way around. For example, a 4 ohm speaker will extract more power from your amplifier than a 8 ohm speaker, about twice as much. The problem most people have with speaker impedances is how to combine speakers safely without blowing the amplifier or speakers.
For connecting speakers in series, the impedances always add. For example, the impedance of the series connection pictured is 16 ohms. For connecting a number of speakers with the same impedance in parallel, the total is the impedance of one speaker divided by the number of speakers.
For example, the impedance of the parallel connection pictured is 4 ohms 8 divided by 2. For two speakers of any impedance connected in parallel, use this formula to compute the total impedance:.
Some examples follow. All numbers are in ohms. Notice that the total for two speakers in parallel is always less than either speaker. You can quickly arrive at an impedance that is too low for your amp to safely drive. If you have some speakers in parallel and some in series, you can break the problem up into parts.
Work out the parallel impedance first, then add the impedance of the series speaker s. For example, you have two 8 ohm and one 4 ohm speakers, and your amp is rated for loads of 4 to 16 ohms. What to do? Paralleling the two 8 ohm speakers gives 4 ohms. Good for your amp. Alternatively, you could parallel one 4 and one 8, giving 2.

Jump Straight to Calculator The calculator below is useful in determining the total impedance of speakers in series. This calculator for amplifier power, voltage and current has little significance but is rather interesting. In the specifications for an amplifier, it might say This distributed speaker system SPL calculator takes the guess work out of which speaker tap to use.
