Quick Check

[midnite8]

Just wanted to check whether I did this all correct...

Using a 4200NEX with an Alpine PDX-V9 full range amp.

First I measured the headunit MAX through the AMP with all EQ flat and gain to MIN. Xovers frequency all the way up. Used track 1. Then I repeated the steps while using track 2.

Second, I set the amp gains by setting headunit to MAX undistorted volume and used track 4.

Finally, for the SUB gains, pretty much same steps as before. Xover frequency all the way up. Subsonic all the way down. Headunit as MAX undistored volume. I used track 5.

you want your high pass filters all of the way down, and low pass filters all of the way up. or set to "bandpass" if there's a switch on your amps for that. in the case of your sub amp, if it has an infrasonic filter, or subsonic filter, then that should be all of the way down, and the LPF all of the way up.
