I am getting a weird humming noise out my subs when the FM Tuner is on. If I have the cd player on there is no noise. Can some help me.

I have a stock head unit with a low power convertor

can someone please help me


thanks

its a bad ground..the humming is probabaly engine noise being caused by the converter your using..try another ground and that should fix it

 

i have the convertor grounded out by stock ground wire that runs to the back of the radio and the humming noise does sound like my engine

 

you should always use a seperate ground..when you start sharing grounds thats when you start getting interferece from the other devices..try moving it to another location and see what happens..also see how close it is to your speaker wire..that will do it too

 

fixed

sure was the ground
