khit po naka AUX or cd meron tlaga ugong, lalagyan ko pla cap. ung ground naman, hindi ko natry un eh, maraming salamat po,

I-try mo yung noise filter na recommended ni tracer1. This could be the one that I am telling you as PI filter. At 60amps ok na ang rating niya. Hindi ka makaka-experience ng voltage dip.
