Is it possible?

I also set mine by ear, but I also know what HPF, LPF, SSFs all do. I wouldn't recommend for a new guy without experience. Don't throw the 2yr old learning to swim in the ocean bro //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

:crap:I never think about that:crap:

Yes.

Wrong

I have had better luck disconnected in past experiances.

Are you supposed to have them in or what someone give me a runtrough really quick pleeease

Wrong

I argue this also. setting the amp with the dmm method will be more accurate if you have the subs attached as you will have the real world imp rise. use the chart's low imp freq and run with it.

I haven't seen any decent argument to the contrary yet with exception of the internal regulated amps.

I'm gonna let the reaper answer this for you as I would really like to see the results from disconnected tuning.

I measure my resistance at the leads to use. So say my components read 3.7ohm and I want 100w rms.

ACV = sqrt(100 x 3.7)

Set HPF ~80hz

Place leads in terminals

Playing a 1khz -3dB tone on a cd slowly turn the gain up until you reach the desired ACV

Plug wires in.

What would I want the ac voltage at

do the calculation. square root of what wattage rms you want to output per channel times the resistance per channel.

The amp puts out 75 rms x 4 at 4 ohms and I want 75 to each speaker

if the speakers are 4 ohm your calculation will be sqrt(75*4)

Ok I get it last question how do I read what ohm my speakers are getting

ohm is a resistance....the speaker presents a resistance to the amp. so to measure their true static resistance you will need a digital multi meter(DMM)

And so am I going to use -3 db or 0db test tone for best results

 

[JuicyJeff 10+ year member]

I have a dmm

I would go with the -3 as it will be closest to true music output

I have a dmm

then read the instruction manual.
