I've installed a Chinese F9212a android hu running 10.1 and connected the stock Infinity speakers directly through the Scorshe adapter wires (front right and front left -+ only, leaving the rear speaker out wires unattached) The problem is the volume set to the lowest position 1, is quite loud. I've tried adjusting the volume settings via the hu settings but no luck. The hu has left and right audio out RCA jacks. I'm considering disconnecting the Scorche adapter speaker wires and using the RCA audio out lines directly to the amp.. Before I do this, has anyone else run into this problem and if so what has been the solution? Would I get better volume control through the amp.? The HU is rated at 60w and this is the internal Amplifier chip: TDA7388. Help to solve this is greatly appreciated!
