Gain control setting

[Ram1970]

Hello everyone. I have a question I hope someone can answer.
I have a Pioneer Avh-120bt head unit, a gm-e360x4 amplifier, two 6x9 in the rear deck, two 6.5 inch in the doors and two tweeters in the front pillars.
I was wondering what would be the best position to set the gain controls on the amplifier.
If it matters the car is a 2006 Impala LT. The 6x9s run on channel B and the tweets and door speakers run on channel A.
The system does sound great but I would like to balance it out if that makes sense.
Thank you...

Not too high, not too low! Usual recommendation is in the middle - high enough to avoid noise and low enough to avoid overload. After that, just experiment if you wish.

Thank you very much for the information. I will try that. If I may ask one more thing I'm hoping you can help. My amp also has frequency settings as well for channel A and channel B. Should I set them differently for the front and back speakers or leave them at the default setting?
