Amp question

[FNG212]

Does amp + receiver Watt per channel add normally? ie. 75W/channel receiver + 75W/channel amp = 150W per channel at speaker?

The reason I ask because I see spec sheets that say 160W RMS mono or 60W RMS stereo (Audio Source Amp 100).

I hope this isnt a "face-palm" question.

Thanks.


I'll ask this in the same thread instead of starting a new one. My woofer is Klipsch KSW-10, probably 3-5 years old. My Yamaha HTR-5550 receiver puts out 75W/channel. Does the self-powered nature of the woofer mean it draws its 200W RMS from the wall or from the receiver. Again, hope this is not "face-palm" catagory

Unless you are bi-amping, you'll only be powering a speaker with one of those - either the receiver or the amp. So, you won't be adding the powers. You'll only be using the power from one of them.

Are you bi-amping? If that's in another thread that I've forgotten, I apologize.

Your KSW-10 powered sub isn't drawing any power from the Yamaha's amps. If you have the power cord for the sub plugged into the wall, then that's where it's drawing its power from. You really shouldn't have the sub plugged into one of the AC outlets on the back of the receiver.

That is not how it works, you will only be able to use one amplifier source at once.

This is only because it is easier for your amplifier to drive one speaker, rather than two simultaneously.

...Klipsch KSW-10...

Your subwoofer has an amplifier built into it, and is drawing only a tiny amount of power from your receiver [not any part of which comes from the amplifier section of the receiver].

....

I am willing to bet that that amp is rated for that 160 watts in bridged mode.
Some amps can be bridged if specified.
On the other hand, an amp that cannot will not put out 160 watts to one channel while only capable of 60 watts in stereo mode.
