Thats not a program.. That comes with one of the test cds for testing your amp..

Not sure which one it was but it came in the cd slot in the case.

o really, did not know that.

is there a program like that out there?

would be nice to have one.

see im trying to figure out what i need to set my 75 rms x 2 amp at.

its for a pair of rf 6x9 .

Your best bet would just to print that image out or a larger copy.

As it is that chart is not perfect as it doesnt take resistance and such into account.

How about doing some math?

i dont know how !! im new to this stuff.

That's not a program, that's just an average. If you want to set your gains correctly, get a small o-scope (DSO NANO v1/v2/v3?). I highly recommend any of them, they're only about $100. I would discourage people to just use a DMM to set gains to "200w" or something as it's inaccurate. That chart is just a giant estimate not considering resistance, frequency, ect. If you set your amp to a specified output and hit the voltage limit of the amp doing so, you'll get clipping. DSO Nano ftw

Great advice minus the fact that the DSO Nano is terribly inaccurate according to tests.

Source? I'm actually curious as i've personally heard nothing but good things. I use mine to set gains all the time. Granted it's not going to be replacing the big dog oscilloscopes anytime soon, but I think it does a great job at small tasks, like setting amp gains.

Is there an O-scope that you recommend? I was looking at Fluke but they are like $2-5k.

yes please post some links. as i do want something that not expensive but good i can use. i was looking at the smd stuff ???

I asked the same question on here a while ago and got flamed for mentioning the SMD DD-1 lol. If I recall it went along the lines of "why would you spend $150 to see a light flash when you can spend $100 and actually see the sine wave." Referencing the DSO Nano. I don't know where your sources are for it being inaccurate as i'm yet to have it fail me..

ok i to would like to know were to get a o scope ? is the nano good ????
