    So at the moment i have the 4 regular lights(high/low, fog) and have 2 100 Watt off road lights, and 2 100 watt back up lights.

    Im planning on adding 2 100 watt bed lights, 2 100 watt spot lights, and maybe 4 rock lights..

    I have a duralast gold battery, Am i going to need to upgrade my alternator?

    Thanks in advance
    -Chris

    You're talking 1000 watts already plus the rock lights.
    That's 71 amps, plus the fuel pump and engine electronics.

    That's a lot not only for the stock alternator and regulator, but for the stock wiring harness from the alternator to the fuse box.
    Even if you are connecting directly to the battery, you could still be seriously overloading the charging side of the system.


    And I'd be looking at upgrading that Duralast to an Optima... but seriously, hit up the audio/video forum, seek out some guys who KNOW THEIR SHIT, and see what they do when running high powered amps.

    ALWAYS keep in mind that people Mickey Mouse shit in their electrical system all the time. It's sometimes out of being cheap, but it's usually out of ignorance. Sometimes they get away with it, sometimes they post a thread about how they toasted their wiring harness.

    High powered lights are no different than a high powered stereo system.
