I have been researching the past few evenings, but can't find the answer I want. For the time being, I just want to add some low-end to my stock stereo. For the most part, the Bose (Clarion) stereo really delivers great sound. The bass, though, is the weakest link.
I want to add an external amp and subwoofer. My question: Does the OEM stereo have any signal processing that lowers the volume of the bass as you turn the volume up? In other words, does either the head unit or the amp that powers the rear speakers, have a safety feature that won't allow those speakers to distort as you raise the volume?
Just by listening to my stereo, I don't think it does (I can hear audible distortion when I turn the volume up). I just want to make sure though, as that could be the speakers them selves failing (cone or surround has failed).
