Opinions on “best” audio settings?

Just got my 23 trd pro and was wondering what are peoples opinions on bass, treble, mid settings? Also is the surround sound option good to have on?

I listen to mostly rock and metal, but I dabble other genres also.

 

I have the JBL. I found that the biggest improvement to my ears was to shut off the surround sound feature. I left the treble, mid range and bass at the factory settings.

 

+ 1. I have the JBL also. Really improved by turning off the surround sound. I've got everything else at factory settings. The bass can be a little muddy depending on the mix of the song being played.

 

Some panel shakes on my left and on top/behind my head, volume at 20 lol and it sounds like all the bass comes from the front. Must be that surround sound shit, I'll give it a try.

 

The best audio setting for (any) Toyota vehicle that I have found thus far is this:
Turn the Volume dial to "0", roll down your windows, and listen to the music from a car next to you, at a traffic light.

 

This!!!
