Can someone help me with my problem?

I put it to the left. Still reads 22-30 volts Dont know why its not increasing higher

If you turn the knob to the left you will be measuring direct current.
This is for all the people saying left

LOL, I feel like a chub. I even went and looked up the symbols to be sure and still got them mixed up.

+1 for you

Check you batteries in you dmm. Or try a different one.

What kind of amp is it.

I'm going off his sig.

Well, the amp Im using is a Clif Designs 4800 model. I think it shouldnt matter the amp though, is there a deck setting or something Im missing? Do you leave BOTH rcas connected too?

 

[krainium 10+ year member]

Check your voltage on your rca at the amp if your dmm is reading correct. And yes you leave both hooked up.

If so something isn't right with your setup.

On there website it says the input voltage is 17.5 volts. I not familiar with the amps so that could be max or there designed to run at a higher voltage.

Looks expensive

 

[jpexpc 10+ year member]

The 17.5V is the Batt+ not the RCA voltage.

Thats what I meant I assumed someone with that amp would know I wasnt talking about RCA voltage seeing the highest rca output voltage I have ever seen is only 8 volts

Thanks for clarifying it.

I think we're on the same page. I would hope someone with that amp would know the voltage it takes.

yeah, thats the one

Is there a sub level volume on the deck? I know mine has one...try and check that..

Also try and see if they rate their amps at 17v....I know MA used to do that before...

I have the spec sheet for the amp in front of me.

Input Sensitivity is: Min. - 7.6V TO Max. 312mV

The supply voltage for the specs was 13.8V

I dont know if those numbers are useful in finding the problem.

Thanks guys for the help so far!!

Oh, and when I unplugged the rcas from the amp and put the DMM on them with the same DMM setting, 2 clicks to the left,

it just shows all zeros, no movement. What should it read at?

 

[krainium 10+ year member]

4 clicks left to measure rca

2 clicks right to measure speaker terminal AC current

Have you checked you batterys in your dmm. I waisted two hours one day because my battery in my dmm where shit.

What kind of electrical system do you have.
