Hi guys, i'm trying to make portable speakers utilising the PAM8403 chip.
i've been reading up on the internet that you want your amplifiers wattage to be more than the speakers, but in all cases in youtube, i've seen people connecting 15W speakers to the PAM8403. why is this the case?
i've bought these speakers http://au.element14.com/pro-signal/abs-224-rc/speaker-20x40mm-4ohm-2w-paper/dp/1761631 , as well as the 8ohm abs-116-rc version and find they work much better (Less clipping) when 5v/1A is connected to them.
Looking at the datasheet output power at 5v for 4 ohm gives 2.5-3.2W, which is greater than my 2W 4ohm nominal speakers. you can definitely hear more clipping than the 2W 8 ohm speaker (datasheet gives 1.4 -1.8W)
can anyone explain where i am wrong? and why my attempt to drive the speakers is bad? or what can i do better with these speakers?
