Humming through stock speakers??

[WiseMaster]

Hey Guys I have been installing a head unit/amp/sub in my car, I had it all wired up and it was working perfectly. However, I was yet to mount the sub, so i disconnected the speaker wires, and because I didnt want the amp to turn on without the speakers connected, I removed the fuse (disconnected the + basically) and left the - , the rcas and the remote wires connected as I thought it would be easier to leave them connected, as I had already mounted the amp to the back seats.

But now when I drive I get quite a noticeable hum through my stock speakers?? Now I have had it all wired up before, and disconnected without any problems, the only difference this time is the -, rcas and remote are were still connected. I have since disconnected all cables but still getting the hum.

I doubt the rcas would do this, and the -unlikely, so I think the culprit is the remote turn on wire...

I tried resetting the battery, didnt work,

Please tell me I havnt blown my head unit

Surely in the manual it would have a warning about this??? I dunno...

Is the 'humming' going louder as the engine RPM goes higher? If so that would be a bad earth (aka negative wire). Happened to myself.

Yay I solved the problem... all I had to do was put the back seats back in and it is fixed

So if you are getting humming through your rear speakers, make sure your back seats are in! lol
