What am i doing wrong?

I purchased an electro-tek multimeter to set my gains. Turn it to AC v~ range 200 and i dont get a reading. HELP!

Is it on?

 

[dirthog 10+ year member]

yes it turns on when i set it to what i want to test

Are you playing a test tone ?

 

[dirthog 10+ year member]

im testing the 545 and I'm playing a 100hz test tone. I have eq and ta turned off.

Ok i put the meter on it again and it reads .7. My hu has a 5v preout and the amp has a digital gain that is set to 4v. Shouldnt it be clipping at this point and read a higher voltage. My goal is 125 watts and the amp was tested at 146 watts.

Your car uses 12V DC current. Set your meter to the 20 V DC setting. Not the AC setting.

NO. DC is for the car's electircal system, yes. However, when measuring the outputs from an amp, the output is AC.

In order to get output to your amp, you need to have your EQ on, so it will send the low voltage to your amp. If there is no input voltage thrugh the RCA's, there will be no output

Make sure your red test lead is plugged into the V - Ohm[Omega] port (for measuring voltage and resistance), not plugged into the mA/A port (for measuring current).

It is plugged into the v-ohm port. How can i test the rca's to how many volts are coming out of it.

I thought i was supposed to turn off all eq settings

You are supposed to set all eq settings flat (IOW: all at 0), not off.
