Yes you can, but You might get damage your receiver.
20 watt
For a 2000-watt speaker system, the receiver should ideally have a power rating that matches or exceeds the speaker's capacity to ensure optimal performance and avoid distortion. A general rule of thumb is to aim for a receiver with a power rating of at least 50-75% of the speaker's wattage. Therefore, a receiver with around 1000 to 1500 watts would be suitable, depending on usage and listening preferences. However, it's also important to consider the impedance and efficiency of the speakers and receiver.
No, 15 watt speakers are rated far to low to be used with an external amplifier.
Yes, the speakers (150W) can handle more power than the stereo (140W) can produce. If it were the other way around (stereo more powerful than speakers), that's when you burn out your speakers.
Why do my rear speakers cut off
100
A 5 Watt amp powers the 4" inch integrated speakers. Distortion is estimated at 0.3% @ 1 Watt frequency response.
4" speakers
The Focal 165-CA1 are 60 watt speakers.
In most cases, the speakers should be able to handle more watts than the amp can deliver. Doing it the other way around will blow out the speakers.
Audio out (line out) from the Home Theater to audio in (line in) on the Power Amp. If you use Preamp out on the Home Theater the Volume Control will control the volume of the Power Amp and Speakers.
