Hello,

 

Can you tell me what is the best settings of canton system?

I have Bolero infotainment system.

It really depends. Some like the mother, some like the daughter.

I have surround off, equalizer custom (bass and treble max and mids about 60%), subwoofer at 80% appr. 

I second linni's recommendations. Also set the soundstage to driver if you drive mostly alone - it really richens the sound. Canton is the best system I've had in any of my cars (Audi, Ford, Merc, BM, Subaru etc)
