Yes, a bigger amp will make speakers louder, but only to a certain extent. It is true that the volume and clarity of the speakers are directly proportional to the amount of power (measured in watts) that is being fed into them. However, the difference in power must be significant before any noticeable increase in volume can be heard. Here are some things to keep in mind when it comes to amplifiers and speakers:
Small differences in power (e.g., 10 watts vs. 15 watts) will not make a noticeable difference in volume or sound quality
Increasing the power output by a factor of 2 (e.g., from 10 watts to 20 watts) will result in a 3dB improvement in volume
Increasing the power output by a factor of 10 (e.g., from 10 watts to 100 watts) will result in a 10dB improvement in volume (which is roughly perceived as twice as loud to the human ear)
If your speakers are capable of handling more power than your amplifier is outputting, you may not be getting the full potential out of your speakers
On the other hand, if your amplifier is outputting more power than your speakers are rated for, you risk damaging your speakers
Overall, it’s important to match your amplifier to your speakers based on their power ratings to ensure that you get the best possible sound quality without risking damage to your equipment.
