    get a DMM put the positive lead to the positive side (battery, amp, etc where ever you are checking) put the negative lead on the negative side (again battery, etc, etc) and set the dmm to DC Volts. If the car is off it should show somewhere around 12.6V, with the car on it should show around 13.8V.

    When I did my big3 upgrade, my voltage didn't raise, but it took longer for it to drop.

    yep it should

    12.6v and 13.8 are with the system off if you are dropping below 12v with the car on and system playing you need to do something to get the voltage up quick.
