    Default Don't Beat Me Up...but...

    I need to know how to make sure that an amp has a common ground. I vaguely remember something about measuring between negative's with an ohm meter and it has to measure below .05 amps...????? Sorry everyone, I'm looking at an amp that I like and want to make sure it works with my SDSs. I'm hosting a little party at the moment (with my SDSs groovin in the background) and can't be rude by sitting on my pc trolling the Polkie Forum. Any help is much appreciated!!

    What is an SDS?
    'Political Correctness'.........defined

    "A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end."

    If the measurement is below 1 ohm (not amps), you should be fine. Meaning, it's a common ground amp.

    Put the meter on "continuity" with the "alarm" on. If it beeps when measuring across the negatives, then you have continuity, or, direct short. AKA common ground. Ohm measurement should be "0."

    Common ground amps do not always test at 0 ohms.

    And "continuity" does not have to mean "low resistance".
