I'm having problems with my dd1 and i have a kenwood head unit i couldn't get the signal light to come on whatsoever i tried numerous things but you're saying you only got yours to show a signal if you turned the sub level to +15? my only concern about doing that is would i be maybe overpowering my sub? but would the gain level just compensate for the high sub level of the head unit?

Is it absolutely necessary to ground the dd1 on the amplifiers ground. i would have to take my car halfway apart to get there is why i ask.
