I have a '19 SE that was spec'd out like the 2020's (all JL, from the factory , 2-12" subs, 4- 8.8" towers etc...), the only difference is the new amps for 2020. The sound quality is amazing at max volume, clear, not overpowered by highs, full and rich across the audible frequency band. I'm sure it's not as loud as REV 10's (what I had on my last boat) at wakeboard distance, but at surf distance the sound quality is definitely superior.
