[QUOTE="tonksie93, post: 8674001, member: 676890"] I have a static high pitched buzz when my cars engine is on. My headunit, DSP and both amplifiers all ground straight to the battery (located in the trunk). When i unplug ONE of the RCA’s going into my DSP’s input the buzz stops. But when both RCA’s are connected the buzz is there, when both RCA’s are disconnected the buzz stops too. I am using the cars OEM headunit and fitting an aftermarket one is not an option. The headunit outputs a low voltage signal through twisted speaker wires, which i have then attached RCA connectors so they can plug into my DSP. Any ideas? [/QUOTE]
