HELP: Think I understand how to set gains

[Raisedin305 5,000+ posts]

I wrote this exact same thing in the Gain Setting tutorial thread but I doubt any one will write back with all those responds tha thread has so I copied and pasted what I wrote there:

Now I understand...for example in my sitaution...

Subs- two 15" Kicker L7s DVC2

amp- KX2500.1

(i want it to get 1000rms to each sub, not 1250rms).

So i do...

2,000(rms) x 2(ohm)= 4,000

4,000 sqrt= 63.245

Therefor I need to set my volume on my headunit to 39 (3/4 of 52) have all my EQ to 0 (bass, treb, sub etc...) With the volume and everything on the EQ down, I raise the volume up to 39 on my headunit, then turn the gain on my amp until my DMM reads 63, correct? This is all I have to do in order to have my gains properly set on my amp? This all done using a 50hz tone.

Question- since I had to set the gain using the subwoofer level on my Headunit at 0 is it still ok to put it up to the max (14/14) without worrying about it blowing or I shouldn't do that?

set your EQ settings to what you normally listen to them at. And leave the sub lvl on 14 so you have a way to lower the output, and you wont be able to raise it

Then yes 63.25volts

Ok exactly, if I want to prevent myself from blowing these, then set them at SUBWOOFER LEVEL-14 then set my gains right?

OK, and to give the subs 1250rms (for competition) I would do:2500(rms) x 2(ohm)= 5,000

5,000sqrt= 70.710

So I would set my gains at sub level at 14 and until my DMM reads 70, correct? Also is 1200rms to my L7s safe?

Is 1250rms safe for L7s?

Also what do I set the X-over frequency to?

 

[Raisedin305 5,000+ posts]

It ranges from 50hz-200.

thats a HPF, right? then set it to around 80 or lower.

Also, about setting your Bass Control on +14... that means you wont be able to boost the bass on certain songs. Leave your EQ flat and after your done, just tune the equalizer settings to your liking with loudness off, just being careful. Dont max out your EQ and play it at full blast.

Music is dynamic unlike test tones. You will almost NEVER be able to send them the full power you set them to using those test tones unless you really push the envelope.

Your talking about me using the bass boost?

How will I know when it's at 80? It starts at 50 then shows little lines that represent it going up by 25. So it goes...50,75,100,125,150,175,200.
