Head Unit Distortion - HELP Please!

[SQPunk]

Greetings all,

I have a Kenwood DNX4150BT head unit.

When I installed this unit, I had no measurable distortion up to 34/35. Now, I have massive distortion pretty much from the bottom of the dial. I am measuring the distortion with a SMD DD-1+ and it shows it as soon as it reads a signal.

This is before the amps.

I pulled the dash loose to replace the heater core in the truck between when it was clean and now. I can only think that maybe a connection got messed up when I did that. However, it seems that the unit should either work or not rather than working but lots of distortion.

Any thoughts?

Thanks in advance,

Maybe swap ur RCA cables for another set and see if anything changes ? Swaping a heater core has nothing to do with ur HU u must have pinched a wire or something. Double check ur work.
