Invest in a good multimeter from radio shack.....they aren't too expensive and are invaluable for many tasks.

 

White noise CD + calibrated lab microphone + spectrum analyzer + graphic or parametric equalizer = tuned system.

 

define tune...its hard to "tune" your system if you only have bass/treble, fade, & balance options. Do you have a graphic EQ, parametric EQ, variable crossovers, time alignment?

 

I have all the above mentioned items. I have an eclipse cd5000 two amps jl audio 450/4 and jl audio 500/1 the 500 is running two jl audio 10w3v3 and the 450/4 is running my front polk momo mmc6500 6.5's no rear speakers.

 

There is an equation to set your time alignment that relates distance with time (delay). obviously, your right woofer would have the least amount of delay since it is the furthest speaker from your ear, and the left tweeter will have the most delay because it is the closest. You measure the distance between your speakers and your ears to get a baseline for your time alignment. From there, you can fine tune it by playing around with the delays until the sound is focused in the center above the dash. You also can play around with the balance of left and right speakers. As for the EQ'ing...it takes an "experienced" ear...unless you have a auto-eq function. that will make things easier. Luckily I have that function on my eclipse 8454 unit. Though I was able to identify the peaks and dips without the auto-eq, I wasnt able to fine tune my system without it. All speakers are different, but for mine, there is a spike between 1.2khz and 3.5khz, and from 150 hz to about 300 hz. There is dip at the higher frequencies...above 9khz, but that might be due to my tweeter being in the stock location. So are you bi-amping the speakers or running them active?
