[QUOTE="DRBOOM, post: 8669614, member: 676005"] The 'pop' noise is a ground loop caused by the voltage drop in your system when there is a surge in power, its pretty common in car audio issues. There a few ways to remedy your situation; [LIST][*]Ground your RCA'S from the source unit - most head units have poor RCA grounding internally. One way to fix this issue is to ground your RCAs' back to the head unit chassis. The way you do it is , disconnect your RCA from head unit, splice some speaker wire and run a figure 8 around the RCA inputs of your head unit. then, apply solder to the figure 8 to hold its shape, and ground it to a point of the head unit. Use one of the screw points on the head unit to ground it. Insert your RCA's back to the source unit. [*]Check your grounding points in your system, from head unit, amp ground distributer and the amp itself to ensure strong connection. [*]Check or upgrade your car battery ground as well; [*]It does not matter how many amps you are running in your ride, proper ground is very important, hence the 12v negative ground as current runs from NEGATIVE to positive terminal from your battery. :veryhapp: [*]Hope this would solve your issue mate! :suave: [/LIST] [ATTACH]4408._xfImport[/ATTACH] [/QUOTE]
