Watts and RMS Watts

Hello, I'm looking to buy a relatively inexpensive stereo for use only in my bedroom.
I found one with 2*2 watts RMS, which I think is relatively low.
My brother has a stereo with a power of 2*35 watts.
To determine how loud mine will be, I need to multiply by 2, so I get 2*4 watts. Then I calculate 35/4, which gives me 8.75. The volume levels of my brother's stereo go up to 40, so I do 40/8.75, which gives us about 4.5. So if I set my brother's stereo to 4, that would be the maximum I could have on the stereo I'm looking to buy?
Thank you for answering me because when it comes to watts and watts RMS, I don't understand much ^^'

Whoa, you're making things complicated for yourself!
Know that there are several types of watts in terms of sound power and that from one device to another, it can be totally different even if they're all in the same watt type like RMS for example because you have products that will do 30 watts RMS that will be much better than others that are supposed to do 80 watts RMS. Each hi-fi/PA product has a sound frequency range expressed in Hz; the lower it is, the more bass it will have, the higher it is, the more treble it will have. We will "hear" it better, or rather we will feel it better, when it is either too much in the bass or too much in the treble because it resonates better within us. And then, there's the respect for the distortion of Hz relative to the decibels expressed in dB, and then how the product is made... and so, even if at one time, 30 watts equivalent to current RMS used to mean pretty loud and powerful, today, it won't do much because the speakers are no longer the same in the budget category and the features are different. Back then, 30-40 years ago, there weren't really any small speakers but big speakers with huge woofers in good thick wood... powered by a well-made amplifier... fortunately, there are still some today, but they don't cost €50, so the low price comes at a cost.
In the 90s, the watt craze came along where there were different watts, for example, PMPO, which was misleading and caused chaos. The more watts you had, the better it was in front of your friends! But in the end, it didn't do much!
Now, to answer your question, 2x2 watts will be roughly like unamplified speakers connected to the headphone output of a portable player without a limiter. You will hear it, but you shouldn't be far away or have noise next to it. A current LCD TV outputs between 2x8 and 2x10 watts RMS, so use that as a reference to get an idea. It also all depends on what you want to achieve.
