Do you have a DMM? If so, follow these directions.

Ok, so I am using that chart, using 300 watt at 2ohm, obviously per the chart its 24.49. Using the meter, i have to turn the gain up 3/4 of the way to get that number, sooooo that cant be right??

Subs are old kicker comps on a hifonics zues.

Not a huge deal, just puzzles me. Ill just put the gain back where i had it but just wanted to know if maybe i missed something.

Thanks
