    Plus, I figure if it was stock for the 05' 325, it probably is just fine.

    Hmm..I'm not sure if I get that analogy.

    but a quick rundown:

    Amps x Volts = Wattage.

    Car systems are set to a static 12V so amperage is the only thing that changes can be amperage to meet the wattage requirements.


    Best analogy is plumbing pipes

    Voltage = Water Pressure
    Amperage = Water Flow Rate

    Water flow will only use as much as is required. ie. Turn signal wants 1A, the amperage will only pull 1A.


    Only thing is to ensure the water pipe (Resistance) is rated for the max water flow (amperage). Since we are going from 120A to 150A, I doubt the power wires and ground straps (water pipe size) will have any issues with the minor increase.

    Lol, that is a substantially better explanation

    Also Ryan,

    It is possible your voltage regulator was wearing out on your 120A. How many watts is your sub system?

    Actually the VR was about a year old... So if anyone needs one of those things...

    It's a pretty small sub, 200w might be generous? Just one of those little infinity things.

    the 120A has about 1440W of power available for the entire car.
    the 150A has about 1800W of power available.

    I wonder what the stock car requires in terms of Amperage.

    That's a good question...

    Considering there is a 90W alternator, it might be far below the 120A max.
