Stock alternator question
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). |

well i will probably end up doing the big 3 when i get my 4 channel and new front/rear speakers.. im more worried about the alternator current output.. will it be enough to support a 300 watt rms mono d amp and a 4 channel amp that outputs 50x4 watts rms (200x4 peak). i am also using a factory battery..
i dont get any dimming with the single mono 300watt amp that i have now.. and i currently have 4 gauge running from the battery to the trunk.. |

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
