[QUOTE="prada14, post: 8661171, member: 675974"] Got issue with a Bit one, Had a Bit 10D before was all fine, replaced it with a Bit one and the noise issue occurred. When I turn the radio on, all fine, a minor click/pop noise but nothing loud. Music plays no whining or any sort of noise. I turn the source off (Pioneer head unit) I hear a whine/ high pitch noise for 2 sec. This happens with the engine being on or off When engine is on or off and source is off and Bit one is turned on with DRC constant whining noise, when I turned the headlights on noise gets louder. When I turn the source on the noise disappears. With the source off, when I remove the RCA cables from the head unit the noise disappears. If I touch the RCA wire to any metal part of the UNIT the noise appears. Any ideas what can cause this, strange this appears when the source is off or turned off only. Tried grounding the Bit one to the battery negative terminal and still no change. Thank you [/QUOTE]
