This should give you sweep volumes of 50dB to 55dB, which i found worked well.
I am on all stock speakers up front ( DLS R4 are not installed yet ) I only have one aftermarket speaker
currently installed and its the DLS424 center.

I could of swore reading multiple threads and speaking with Taibainl & Technic when using stock MS8 internal amp
(only my underseats/sub are amped). you want to do 21-23db for the calibration and this made the biggest improvement earlier on.

Any lower and volume was sounding like crap if you followed earlier in the thread we have tried multiple calibration
volumes and nothing began to sound remotely good until I got to 21db or so.
