Hi
About 6 months ago I decided to install an amp and a few subs into my car. All was fine until a few hours ago when I was coming home and I hit a small bump (man hole cover) and my speakers went crazy, they were whining very loud, loud enough that I could not hear the music at all. so when I got home I checked all the wires to see if any were disconnected and yes one of the speaker wires wwas but when I connected the wire back to the speaker the noise continued.
I tried conecting one speakers at a time and the noise persisted then I tried turning the gain on the amp down (didnt work) I tried switching fuses in the amp (didnt work). Basically disconected every wire and connected them again (didnt work).
Also I would like to add this sound is not coming from the alternator as I fixed that problem a long time ago and this whine is 100% worst. Also this sound even happends when I have the car running solely on battery
Any advise would be appreciated as I have exhausted all of my ideas.
