Pac unit will not fix your problem.Most factory radios do the same thing. If you use a JL Audio Cleansweep, it will fix the problem by providing equalization AND a new volume knob. Once tuned, your factory volume will remain at the level where the system was tuned and you will use the JL Audio volume control as the main system volume (all speakers must be amplified). -or- Add a sub volume control to the sub amp and tune the amp for maximum output when the factory radio has not started to lower the bass output.
