That means it will have a significantly larger dynamic headroom with noticeably lower sound distortion. When playing songs, the high-scale female vocals or lead guitar solos will sound momentarily better and shriller since these passages can consume up to watts in peak wattage.
However, it drains a lot of power from your car battery too. On the contrary, not having that much wattage in reserve can make those specific segments of the song sound hopelessly distorted. So, in the end, it all comes down to the RMS wattage and sound sensitivity rating for all-around performance.

The wattage in car stereos is the power it can provide to amps, speakers, etc. RMS wattage or root mean square wattage is the continuous amount of power that a device can handle. Peak wattage is the power that a device can handle for a shorter time, not continuously without risk of being damaged. RMS wattage is always smaller than peak wattage. This 50 x 4 wattage rating represents the peak power rating, and it is different from RMS ratings. The RMS power available per channel, in this case, is between 10 — 15 watts which is not sufficient to operate a high-quality sound system at higher volumes.
The peak power rating of an amplifier or head unit represents the power output for shorter bursts, like for a single loud note, but the RMS wattage rating measures the constant power output. Higher RMS of car stereo means that the stereo can deliver higher wattage for an extended time. Aftermarket car stereos can produce more than 20 Watts RMS per channel, ensuring no distortion at higher volumes. Moreover, a higher RMS rating car stereo can handle more powerful amplifiers and other audio equipment without burning itself.
In most car sound systems, if you want a good audio experience, you have to upgrade your factory audio. By upgrading, I mean using a high-end car stereo, amp, speakers, and they need more wattage for louder sound. More wattage does mean better sound. While wattage is an essential factor at higher volumes, the efficiency and sensitivity of speakers also play a huge role. Doubling the wattage does not mean that you get twice as much as sound output. It only leads to an increase of 3 dB.

There can always be exceptions with some car manufacturers and car models. However, the standard factory wattage in car stereos lingers around watt RMS.
