This question is directed to those of you who are running any or all elements of the following system (or have an opinion as to my question):

Alpine CDA-7893
JL Audio 300/4
JL Audio Stealthbox
JL Audio XR650-CSi Speakers

What settings are you using?

For example:

For the Head Unit
Bass Center Frequency
Bass Band Width (Q-Factor)
Bass Level
Treble Center Frequency
Treble Level
High Pass Filter
Low Pass Filter
Time Correction Settings
MX Mode Level
Subwoofer Level

For the Amp
Rear Channel Filter Slope Selector
Rear Channel x10 Cutoff Frequency Multiplier
Rear Channel Filter Cutoff Frequency Selector
Rear Channel Filter Mode Selector
Rear Channel Input Voltage Range Selector
Rear Channel Input Sensitivity Control
Front Channel Filter Slope Selector
Front Channel x10 Cutoff Frequency Multiplier
Front Channel Filter Cutoff Frequency Selector
Front Channel Filter Mode Selector
Front Channel Input Voltage Range Selector
Rear Channel Input Sensitivity Control
2/4 Ch Input Mode Selector

I've been tinkering with all of these for some time now, and feel that I've hit "optimum sound." However, I'm curious what others have.

Thanks for your time.
