Im not the seller, not talking crap without having those head units in hands..i use mcintosh amps and alpine f1 spekers in my car..directly comparing those hu's n pick one which is the best for my setup..im not like u, perhaps if made in china hu rebranded as pioneer odr, u will say its amazing just bcoz its expensive..pity for rich guy like u, please upgrade ur knowledge b4 flaming others..or maybe, should i teach u to make cheap things works great? Dont get angry if u believe ur self as knowledgeable or experienced enough, but act like one..peace
