RMS capabilities - Toyota Yaris Forums

Fist off speakers do not actually "pull" power/watts.
They simply utilize what ever the amp is capable to deliver.
It you attempt to drive an amp beyond its capabilities, it will simply begin "clipping" the wave form or go into some form of oscilation. This happens all the time (even with the stock sys) when you turn the volume up louder than the amp is able to reproduce cleanely. This usually does no harm to the amp.

The obvious solution is to match speakers and amp to prevent this. IMO there is no substitue for amp wattage and efficient speakers.

For every increase in 3 decibles, about double the wattage is needed to reproduce it cleanly.

Rember the deal where you take a penny and double it every day? By the end of the month you will be a very rich man.
The same priciple hold true with amp wattage. So, to stat with very efficient speakers to begin with, you are ahead of the game.

To add to this, very high and low frequencys need even more wattage.

Bottom line, I would seriously consider installing a seperate amp for the sub with the proper "crossover"
