heres exactly what i did just to make sure i did everything correct. i removed the pos speaker wire from the amp. then on my headunit i put everything at zero. popped in a 50hz test tone put my volume up al the way to 27. set my dmm to read ac voltage. then put the ends of the dmm into the positve terminal of the amp and i slowly turned up the gain. i got about three quarters of the way until i hit .8 i dint want to go higher cuz i wasnt sure i was gonna damage the amp or not.

He probably has the DMM set wrong.

Those cheap DMMs are weird at time. If you needed 80 and it was showing .8 I bet your good.

80 and .8 is a HUGE difference...

i did use a 50 hz tone. are my calculations correct tho?

use a test tone not music.

Well if you run your numbers correctly you should show 80 on your DMM. But you have to be playing a track and you need to have the volume up.

Also note this is AC Voltage, so it VARIES! So you gotta watch the meter until it hits the number.
