ac and DC voltage

[inferno1985 10+ year member]

What is a good voltage ac wise coming out of the amp speaker terminals?

and same goes for dc. If applicable? Is a amp supposed to send out dc voltage?

What setting to use on dmm to read ac and dc voltage. Thanks

Voltage depends on amp

Should be AC, not DC

Use AC for amp output

12-14V DC going IN to the amp, AC coming OUT of the amp. The voltage depends on the impedance of your subwoofer as well as the size of the amp. A 3000w amp is going to output a much higher voltage than a 500w amp.

And no, there should be no DC coming OUT of the amp just like there should be no AC going IN. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I mean like what setting on the dmm. Ac for Ac current and dcc for DC current . But my dmm. Has setting of. 200m.2.20.200.600 what of those setting should I use to check for Ac and DC voltage out of the amp terminals.

20 DC for amp inputs.

I don't know what amp you have, but 20 or 200 volts AC for output.
