Hi All, I have recently ICEd the car speakers front Infinity Component Rear JBL Coaxial Sub Diamond JBl 646 4 ch amp 800W Cerwin Wega Mono bloc 500W But I am deeply worried about the Sound quality. The sound is pathetic. The same setup was used in my previous car and was amazing. Seriously thinking of changing the HU or adding an Audio processor. HU in mind is KenWood 8016/ JVC KDR 90BT. Audio Processor Infinity IMS(4.1). Would the addition of Audio processor enhance the sound quaility? Please share your valuable inputs. I haven't witnessed any audio processors so unable to make a choice.
