    Hi all,
    So I have a 2006 V6 SR5 half cab Tundra. I have a 12” sub with an amp and capacitor installed, along with a pioneer head unit. My question is, would I be able to put in a dual rack light bar and get away without needing to change any of the electrical system, or would I need another/bigger alternator or battery?
    Thanks for the help!
    Mike

    It really depends on the amp draw for the new light bars. Many stock alternators can handle a bit more load.

    If the new light bar is LED it shouldn’t be pulling that much voltage. Shouldn’t be an issue.

    How much amperage are you looking to add? What is the added draw going to be?

    How many watts is your sub amp, and how many ampheres does it draw?

    What kind of light bar? Assume it will be LED?

    I(Amps) = P(Watts) / V(Volts)
    I(A) = 120W / 12vdc
    I(amps) = 10 amps or 10000milliamps

    Pie!
    That's not much added load. A quick search shows that your alternator might be 100 amps. I don't think 10 amps or so is going to kill you, but stereo stuff and a worn out alternator or battery wouldn't like any more load anyway.
    If your alternator and battery are good then 10amps is pretty small.
