Car on or car off, when hitting a button on the touchscreen, like volume up and down, or selecting anything, I get a thud from my subwoofer, not real loud.
Tried different ground points on for the headunit, I don't get alternator whine or anything. Gains on my amps are excessively low as I have way more power than i need 3000wrms for a 1200wrms sub, and 150wrmsx4 for my mids and tweets.
It is a minor annoyance, I but was wondering if anyone has experienced something similar with the nex units.
