Alway gotta have more cowbell man! What if it was for a sub or I load my speakers to 16 ohms? Sometimes people's needs and wants don't always align with what u need or want
you can parallel even 100 of them, with a 16 ohm load it will mkae no differece in the positive way, just degrade sound.
you could paralell bpa300 amps, witch would be dreafull to start with, but you won't get even a fleefart more if the load is not adjusted to suit it.
and btw, it would need a load with less impedance.
one you attempt paralelling 3,or4,or more chipamps, and then bridge them its a better solution, but still would be dreadfull as to utilise the extra current capacity you would still need a low impedance load.
witch makes kindof less sense than you think.
automotive subs can be configured to be 2 ohms, or even less, 1 ohms impedance, that could use this beef of current, but it will most likely sound horribly in a living room.
the problem is, ability to produce more output current does not alone yield any power. you need higher voltage, or a more demanding /low impedance/ load.
bpa amps achieve more output voltage by running in bridged configuration, hence have larger swing at the output voltage wise. now, higher voltage into the same load requires more current. that is why its paralelled, to have that extra current demand met.
any further paralelling is only reasonable if your load requires more current.
you can nt increase the voltage swing any more, as the chip can not handle more. once bridged, it can not be bridged again.
and there is your dinner.
