Help with settings

[BRITBOY 10+ year member]

Okay, so I have just installed some CDT Audio EF-61CF 6.5" components with SatNet 400 crossovers powered by a Clarion DPX2250. My head unit is a Panasonic CQ-C8803U which has 31 rms (for the rears) and has 5v pre outs. The amp has a switch to select input voltage but I'm not sure if the pre out voltage of 5v is the rms or max power. Now I have the gain at about a 1/4 turn and it sounds great (rears distort before i can get fronts to) The amp also has low/high pass filters, should I turn them to off as the crossovers should do the work?? I would like to use a test tone to set up the fronts, can someone recommend a frequency?? and can someone explain how to set up with a tone. As you can tell I am fairly new to all this but am very eager to learn some stuff.

Thanks

Test Tones http://www.realmofexcursion.com/main.htm

I always use Amp Filters HP LP Subsonic.

Look at the box your speakers came in. There should be a Frq responce chart. Look at the Dips and Rises these are DB charts. Were they dip and rise try and get them level all the way across, Is the Holy Grail. Most are pretty close.

Look at the frq where these dips and rises are. These will be a good starting point. If its 3db high, Then see what 3db cut will do. This is all trial and error stuff.

To start with, Turn off all EQ, Bass boost etc at the HU. Disconnect one speaker wire from each speaker. Turn the gains all the way down. Turn the HU Volume to around 75%. With a DMM RMS meter you will check voltage output across the wire that is off and the connection it would go on.

You need to know the Amps total watts. Take that number divid it by your speakers ohm rating. Take that number and square it, I assume you know what that means. Now write that number down. Take you watts again and divid it by that number you wrote down. That is your target voltage output for the amp.

If its a Mono Amp use a 40, 50 or 60hz Test tone, For mids and tweeters use 500hz, 1khz, 2khz and a 4khz. You can use a sine sweep from the above site that can run 20hz to 22khz. You are listening for a smooth flat responce across the board. You just have to play around till you like what you hear.
