Loud buzzing tho speakers when engines running - HDIkyle - 11-05-2013 Got a loud buzzing thu speakers but only when the engines running. It did it also in the estate but I thought it was a bad stereo earth. Running tho a give amp. It also gets louder with the engine revs. RE: Loud buzzing tho speakers when engines running - Eeyore - 11-05-2013 Neaust told me it was noise in the speaker circuit from the injectors. Makes sense with it getting louder with engine revs. So yeh. Probably a bad earth? RE: Loud buzzing tho speakers when engines running - HDIkyle - 11-05-2013 On an XUD tho there shouldn't be any noise from injectors RE: Loud buzzing tho speakers when engines running - Danny2009 - 11-05-2013 Deffo a bad earth mate where you earthed the amp to? RE: Loud buzzing tho speakers when engines running - Choppin - 11-05-2013 It can happen to any car mate, just a bad earth, try relocating the amp earth, can also b phono cable picking up a signal, I kno it sounds a lil odd but had it in an old car, moved the phonos and the buzzing stopped, hope u find the problem mate RE: Loud buzzing tho speakers when engines running - Tom - 11-05-2013 Bad earth or shit RCA cable. RE: Loud buzzing tho speakers when engines running - HDIkyle - 11-05-2013 It's earthen the the isofix support bar same place as battery. Turned gain down and it stopped then i got a bringing noise and smoke from the amp but its still working ok :/ its a vibe a3 Gona try get another amp to try to see if it is the amp or not RE: Loud buzzing tho speakers when engines running - Ruan - 26-05-2013 It's picking up the poorly rectified DC output from the alternator... I'm fairly sure alternators work on full wave rectification, so this is what you're hearing. You need a ground loop isolator. http://compare.ebay.co.uk/like/170602063703?var=lv&var=sbar&_lwgsi=y&cbt=y&device=c&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0&ff12=67&ff13=80&ff14=66
