Help deciding about the Ibiza HiFi?

Hi! I’m going to order a new Seat Ibiza! But there’s something bothering me…how’s the stock audio system in the car?

It’s the BeatsAudio worth taking in consideration having to spend 1900€ (600 the Beats, 1300 the 9.2” mandatory Navi)?

Are the stock speakers good enough with good bass?

Please owners of Ibiza, help me!
