Setting gain with DMM

[Decado2 10+ year member]

I have a Kicker kx2500.1, I am running it at 2 ohms for max power, but, I have a crappy Pioneer HU with the super powerefull 2 volt preouts, if I am using a dmm to try and set the gains right, what # should my dmm read for 2500 watts rms?

I am looking for the answer to this question too (except i need to calculate 250 watts lol)

Search doesn't help at all here most of the time. It brings up a wide variety of stuff.

i believe it is 35 volts

i believe it is 35 volts

What about for 250 watts RMS //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

My amp is 500 watts and sub is only 250 so I want to get it right around that number.

Ive read a lot of that and I still can't figure it out

don't use this till confirmed by someone else, but i think it is sqrt(wattage/ohm)

Sqrt(Power*Resistance) = Voltage

Ok so its

The square root of (Wattage divided by OHM?)

no sqrt(watt*ohm) or just use the link i posted

Ok so does this sound right to power my 250 watt RMS sub at 4 OHM I need my multimeter to read 31.6 when connected to teh amp?

Ok cool thanks.

Should I set my analog multimeter to 50 AC on the dial before I plug it in I guess?

I searched, it didnt bring up much //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif , I did find out on ROE that the voltage I need is 70.7 though.
