I would like to know what is the best way to configure volume on stereo and amp.
My stereo is Sony MEX-BT3800, but, at the moment I can't remember amps Model.
On stereo I have subwoofer output and option for subwoofer volume. It has 21 steps:
-10 - - - - 0 - - - - +10
Do these steps mean
1. 0% - - - - 50% - - - - 100%
2. 0% - - - - 100% - - - - 200% .
So, at what level should it stay and start configuring volume on amp?
Or should I max out amps volume on 90-100% and adjust volume on stereo?
