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

4" speakers
The Focal 165-CA1 are 60 watt speakers.
A 5 Watt amp powers the 4" inch integrated speakers. Distortion is estimated at 0.3% @ 1 Watt frequency response.
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.
It depends on the power and impedance rating of the 12-inch speakers. If both speakers are rated for 175 watts and the amp can handle the impedance of the speakers, then the 350 watt amp should be able to power both speakers effectively.
