My english isn't good, but I will try to post something...

I use a guide called "Sparky's Audio System Survival Guide", it says.. I tried to find the link but no success

For 2500RMS you should read using a 60hz tone the next Volts

at 4ohms 100V

at 2 -> 70,71V

at 1 -> 50V

at 2.667 -> 81,65V

at 1.5 -> 61,24V

and at 1.334 -> 57,75V

I hope this can help you

Alright I got a ton of questions here
Ok first my head unit has a thing that says woofer then you can change that from 0-9 when I put it on 0 the DMM doesnt get a reading so I turned it to 5 and set my voltage to 31.3 with that is that the best number to put it on or should I turn the woofer all the way to 9?

another thing

I have this thing called Circle surround which puts tons more bass into the speakers and you can adjust how much bass you want in the fronts and rears. When I do this set my rears and fronts true bass to 3 and the woofer to 5 I get about 6 volts less on my DMM. Should I tune my system to the Circle surround option or what?

Look in the instruction book that came with the DMM it tells you how to measure DC and AC, it's not that hard to do

put that on 9 then set your gain to your voltage u need, that 0-9 is prolly your sub level out.
