SIDE SHOW Posted February 25, 2015 Report Share Posted February 25, 2015 Remove the remote wire so the amp doesn't turn on, test and see if the noise is still coming from the amp. did it only just start doing this? or did you just finish installing the amp?

Skullz Posted February 25, 2015 Report Share Posted February 25, 2015 Make sure all ground straps on the truck are good and not broken, funky electrical things happen when ground straps break. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
