Stock alternator question

[09sedan]

whats the stock alternator amp output on a 2009 toyota yaris ? car has 45k kms on it.

all im running for sound is a 300 watt RMS mono amplifier ( powering 2 kicker 10 inch COMP subwoofers) do i need to worry about a capacitor or upgrading the big 3? ( i dont think ill be getting a louder system in the future).

Im not sure about any of the other questions but I know that a capacitor helps Buss stability. Ever see one of those cars thats really loud and every time the bass hits the lights dim? Thats caused by the huge current draw from the amp. A capacitor helps to keep the voltage available at the buss more stable and can supliment large current draw for short periods of time (eg when bass hits) But I know little else about sound systems

Good Luck
