Personal preference =in studio mode , loud on , crank up base to max, treble @ approx 75% , Fade and balance as appropriate, volume about 19-20. Should be ok for those who like it hard and fast.eg Birdman, Iggy ,Saints, Ozzy , et al, Rear windscreen vibrates and shimmers nicely. Bear in mind this is a car unit not a home thunderbox.That said it is OK , but I expected a little more for $1k large, but I would not be without it. And to Kens point , I couldnt be bothered with an aftermarket Jobbie.
