The set up I have now is still packs a punch to make herself cringe and mortify the kids from a hundred yards(old euphoria cds).but there is more to it than just volume.
I never had this on Adverts. And yes I have the calibration CD
You can get outstanding sound quality even from an OEM unit, as long as you have the right signal and the processing is done outside the BM radio module.
I would love to listen to your car, meet me up, we can discuss options and share thoughts and experience.
