Bought a new head unit. Max volume number is 40. The dd1 is showing distortion at 28 through speaker outputs.  It doesn't show any distortion through the rca outputs at 40/max (signal is registering).  Is this possible (due to the quality of signal, error, other)?  Tried switching up jacks as well. 

 

Thank you in advance

Speaker outputs ? Do you mean using the built in Headunit amp? Those all distort we ll before your rca preamp outs distort

Normal

If you're using exclusively RCA outputs, yield to those numbers

Else you can do some mix/matching. Use -5db for your HU speaker outputs provided the RCA outputs are clean at the same level w/ -0db, then tune your sub amp at that same volume level with whichever gain overlap is appropriate for your goals

I have another question for those that can maybe help. Got my high and mid stage set on a 4x100 channel. Got the undistorted reading from the amp gain about 1/3 turn) at full volume from the head unit(also previously checked for no distortion) . I wanted to turn down the amp sensitivity slightly to match the ac volts / watts for my components. However, the voltage is way over what it should be for the channels. Everything is turned to zero on the HU to get flat signal. For example : used zero db 1k signal test and the voltage is way more then the amp says it produces. Trying to get to about 14.1 volts and the no distortion level is like 24 +-1 volts.    Why is this?  If a no distortion level on a 100 watt channel is registering 130 to 150 watts. Amp is jl xd400
