15' M4 with HK audio...

My bass has def dropped off all of a sudden. Currently getting sound with decreased bass and just need to know how to check if I need a new amp? Any help is much appreciated

Multimeter at woofer connector, play 40Hz tone, see if 30V+ is measured at max volume. If not then OEM amp is gone.

So I've never used this before and I want to make sure this is the right select setting?

Nope.

You are set to resistance, not voltage.

Turn towards 10 o'clock.
