Amp Question

[NewToyotaYarisOwner]

Hi,

So i just got a 2010 2 door hatchback yaris and was wondering about its sound system. I've been reading about getting an Amplifer but aren't sure if i'd need one. I've boughten a new pair of rear speakers that say the max watts is 180, and the nominal is 30. The front door speakers say the normal watt is 25 and max is 140. So my question is, whats the normal watt power for the stock car? I'd rather not buy an amp unless its needed....

Thanks!

The factory radio is about 8 watts. Look at those magnets on back...cute little farts aren't they,lol

And how do you like your new toy? Ever spent time in a previous version. Curious on comparisons.
