I was impressed by the quality of the standard sound system.
I'm picking up my new Cupra ST
280 tomorrow with the Seat Sound package, but I was listening and tuning the sound in a car with standard sound setup a week ago.
The standard sound system lacks the high-end clarity that the really expensive systems has but sounded pretty clear to me, certainly above the level needed to enjoy your favorite music at high volume regardless of your music genre preference.
The mid and bass was plentiful, I was not expecting this level of base without the sub of the seat sound package. As mentioned its not very "tight" but not excessivly loose either in my view. I had the bass turned up a lot on the EQ.
Overall a really nice standard sound system!
Looking forward to listening to the Seat Sound package system in my new car tomorrow when driving home from the dealer!
