Have a2019 crew with the 6 speaker Bose system .I am dissatisfied with the performance the bass distorts pretty bad and vibrates the front door panels horribly. I am looking into adding a sub in the back what do I do with the front door speakers? Bass block ?turn them into a mid bass ? Unplug ? Dose the Bose amp only send low frequencies to the front doors? Does anyone know the frequency these are playing ? Would like to put in some 2 ohm coaxial however I fear they are only sending lows to the doors
