QuestionYeah, i do have an amp in my trunk. It did not have this noise when it was in my other car, so do you think something may be loose, or do i have to get something else to dampen this sound?
Thanks

Question -
I recently moved my aftermarket stereo from my old car to my new car, but now the rear speakers have a loud whining noise coming out of it when the volume isnt turned up. This noise is connected with the accelerator, everytime i hit it, the noise gets louder. Do you know what i have to do to resolve this?
Answer -
well it sounds like a ground loop, when you say it's connected to the accelerator and gets louder I think what you mean is that the pitch of the whine changes to sound like the engine reving right? not louder but higher pitch?
that's signature of a ground loop.
do you have any amplifiers or is it just the head unit (cd player?)
Thanks!
Answeryup definatly a ground loop then.
usually these are created in the connection between the amp and the head unit. to find out disconnect the amp from the headunit. you are using RCA connections right? not speaker level? if so just disconnect the RCAs and turn the system on, start the car,etc. you wont get any music of course but the idea here is to see if the noise went away. it should be clean and noise free. let me know if it is or not.
Next step is going to be to hook a speaker directly to the speaker outputs on the cd player and see if there's any noise there (again with the amp not conected) hopefully you'll have a spare speaker laying around to do this or you can temporarlily remove a door speaker to connect it directly here. again let me know if there is noise or not.
I suspect that when the amp and head are disconnected you wont have any noise from either but when they are connected together then your noise comes about.
Let me know and we'll move on from here.
