lets say i rebpace a 25 watt speaker for a 45 watt speaker
will it sound louder?
Well it obviously depends on the amp you got powering it. If it's a 25watt amp it will most likely sound the same as the 25watt speaker.
yes, but youll have to upgrade the amplifier

I clicked System Restore and it said "System Restore Is Unable To Protect You".

Watts don't determine the volume of a speaker, sensitivity does. Most manufacturers will have the sensitivity of their speakers listed somewhere, though the process varies from company to company so you can only compare speakers from the same company for volume. What speakers are you looking to replace?
