This will need to be checked to see if this Pioneer unit is self amplified for speakers or if it requires an amplifier.Most likely it requires an amplifier and either its amplifier has failed or the component in the trunk that is missing was the amplifier.The wiring will need to be traced to see if an after market amp was installed and whether it is still in the vehicle or if it was removed.This may be best checked/tested by an auto accessory install facility as they may know where any after market amp was installed as well as be able to test it in some cases to see if it needs replaced,if the command needs replaced or if there are any shorted speakers needing replaced.
