They seem to think there is some DSP chip built into the HU so not as clean as aftermarkrt unit. I had a 06 Civic w/factory Nav did the same thing and it rocked.
Not sure what to do now keep tweaking? JL audio make a product call clean sweep takes all signals from factory HU to flat and work up from there.

That would be the next step. The clean sweep is a nice product but a little pricey. You might also want to check out the audiocontrol products. I used one of the LC8s a few setups ago and was pleased with it.
