[QUOTE="CaptCrawfish, post: 8262519, member: 661072"] So I decided to redo my wiring, really just reorganize it. I began doing all this without disconnecting the negative on the battery because I was fairly confident that I wasn't going to short anything out and didn't want to have to reset all my settings on the headunit. Before we begin, it's important to note that when I plugged the positive wire into the amplifier it gave a spark, I however didn't think anything of it and continued on. I have 2 amplifiers, one for my subwoofer (MB Quart) and one for my 4 speakers (Rockford Fosgate). I simply began binding wires together and what knot until it looked to be finished. Eager to hear my system again I turned the key to the ACCESSORY SETTINGS, not actually running, only to be greeted by a nice, loud buzzing sound. This is not engine noise, because I know what engine noise is because I have that too, but I have a ground loop isolators to solve that...bla bla bla needless to say I did my best to get rid of that problem but simply couldn't so I decided to try ground loop isolators which did the trick. That however is another story for another time. So... I was greeted with a brand new buzzing sound (very loud too, something you can't drown out by cranking up the volume) even when the car isn't actually on.
