The rear audio seems as if the factory amp has went out but just for the rear. Front has bass and works as should rest has extremely muffled audio way lower than volume control and no bass or mid range whatsoever. My question is is this an external amplifier hidden within the body somewhere or an internal one within the head unit itself, or possibly even something else?
Van is equipped with the entertainment package having 2 DVD players in the rear with the unit at the bottom of the dash and the upper is the touchscreen unit with the cd/DVD player built in as well has side buttons also along side of screen, believe has everything except the navigation. Thanks.
