    I thought I'd use the V^2/R because I know both... perhaps silly question but where do you measure amperage in this situation? and would the voltage youre speaking of be 12V or the AC voltage measured?

    The amps I'm almost positive you measure it off the power/ground and voltage is off the speaker terminals.

    Also though you have to take in your amps efficiency to make sure you're not clipping the signal. Thats why they say its not the best way to set your gains.

    I did not consider this. hm...

    feckin numbers. Would finding the power this way would be an underestimation of power as nothing is 100% efficient, or would it just screw up the calculation altogether to some extent?

    Also, speakers do not have resistance... so do not use that formula including resistance.... Speakers have an impedance which changes depending on the frequency being played, box size, and vehicle.

    Thats where it gets real confusing and O-scopes become your friend lol.

    Yeah, because you're giving advice like you've been around them forever.

    Re: Correct way to set gain with DMM?

    this is all too much hassle/math....
    I'm gonna stick to the ol' small *** flat head screw driver. I've not blown a sub or amps ever.
    I would like to see if my tuning is close using a DMM tho, but don't want to spend the money.
    That JL link was good!
