Default Setting Gains

I have the CDT 6.5" EF-61FG Components in the front that are rated at:
Power handling: 140 watt RMS
Frequency response: 60-20kHz
Sensitivity: 91.5 dB
Impedance: 4 Ohm

I also have the eD 13Ov.3 subwoofer rated at:
Dual 2 Ohm Voice Coils
600/1000 watt RMS
I will just wire each coil to each channel on the amplifier.

The amplifiers thatI will be using for bothare the eD NINe.2x rated at:
200 watt x 2 @ 4 Ohm RMS
300 watt x 2 @ 2 Ohm RMS
600 watt x 1 @ 4 Ohm RMS

I have a test tone CD that has the following tones:
20hz
40hz
60hz
80hz
100hz
200hz
300kz
1000hz

Which tone should I use when setting the gains for these speakers on these amplifiers? I want to get the best sound with out blowing the speakers. Any suggestions/help is much appreciated.

I am kinda going by the video from Elemental Designs. They use a 50hz tone when setting the gains on an amp.

I couldn't tell you exactly where to set them, it's by ear for me. Or some good shops will even have an oscilloscope they can use which with the right installer can get everything set up very nicely.

Test tone cd's work good, something even better would be a program like WinISD. you can do tones from 10 hz-20,000 hz, you can do sweeps from any two tones in between there, fast or slow, just so long as your head unit has an AUX input, you you can just run it strait into your amp using a Y cable. I am yet to go out and mess with mine with my laptop and ISD. Use a good blend of songs if you do it with music though. Even if you don't like metal, pop, jazz, rap or whatever, find a cd or download some songs if thats what it takes.

P.S. WinISD is free you can just google it and download it.

WinISD is what I used to create my test tone CD. I'm just trying to figure out which tone out of the 8 I listed that I should use for the front components and for the sub. I am figuring I should use 40 for the sub but I am not really sure for the comps. I had blown a speaker in the past using the tones and I don't want to do that again. What should I listen for when the gain is getting to high?

You speaker maxing out.

You'll honestly want to do a range more than these
20hz
40hz
60hz
80hz
100hz
200hz
300kz
1000hz

What kind of head unit is on all of this?

Eclipse 3100

You recommend hooking my laptop directly to the HU and running the WinISD from that?

Yeah you have an AUX input. Get a Y splitter with the mini plug to rca plugs on the other side and plug that baby in, see how that sub handles some 10 hz's! Do some sweeps, you basically want to get multiple frequencies to have about the same actual volume, by adjusting your crossovers, eq etc.

I have never used test tones nor seen them used to tune a system unless you are going to use an o-scope. Pic a few of your favorit cd's, stuff you know well..........
