XtremPro Hi-end Ground Loop Noise Isolator/Filter for Car Audio/Home High-fidelity System - Black (65042)

Hi does it affect the audio quality especially for high end equipment?

What if my reciever has only one lfe subwoofer rca output, and my subwoofer only has one lfe input?

I have my home reciever plugged into a pure sine inverter. will this unit work and how do i use it?

this works on my amp hifonics 4000 watts ,when i turn on the signal lights my subwoofers make noises Everytime lights blinking
