Why does the car still hiss and pop with a completely balanced circuitry?
In all honesty I have no idea and I have failed to get an electrical engineer to give a damn to investigate.

I found that even the TWK was not enough to buffer the REALLY bad noise caused by my ST-X amplifiers and a loaner amp I used for testing. I had to swap in the power RF amps to get it livable. Its worth a try but make sure to put on lights and actually drive around under load.
