What would you do if your stock radio doesn’t sound like the top brand sound system? Alpine comes up with the system integration audio processor to help it possible. The PXE-H650 uses Alpine’s Imprint sound tuning technology that allow your components to sound like a high-quality Alpine unit.
The PXE-H650 allows you to upgrade the sound quality in your vehicles by correcting the acoustical problems with its AntEQ technology. The PXE-H650 removes the factory equalization and adds Audyssey SoundEQ XT to optimize the sound quality of your system. There is not much more detail on this from Alpine yet.
