[xbotzz]

Hi... i am having this irritating static noise from my amps...

i have disconnected my HU to troubleshoot... so it just both my amps to woofer and another to front/rear...

when i switch on the amps... i get this static noise but i am hoping for total silence...

i am getting from both the amps.. and i have redo the grounding... , still same

what else can i do ?

maybe change to different ground point? make sure got no paint on surface.

also check the rca cable itself, and also rca terminals on amp and HU..

wrap your RCA cables.. they are more likely to get infected wid those noise.try best not to run your rca cable parrelel with your amp power cable or ground.

if it have to meet somewhere with other wires cross them and wrap the cross sectional area with anything u can think off....and also tin foil might help....
