[QUOTE="wew lad, post: 8488291, member: 665412"] its coming from your headunit... or a ground loop between your headunit and your amps. the reason i say that is because when you turn the volume up on the headunit it's essentially increasing its signal, including all noise (there's a noise floor you're trying to avoid). if it stayed the same at any headunit volume i would be looking at the amp more than the headunit is there noise with the dsp unplugged from the headunit but pluged into the amp? I assume your signal chain is phone> hu > DSP > amplifier > speakers does it matter what source your headunit is on, does the noise change? [/QUOTE]
