I have recently started having problems with a whinning sound coming from my front right speaker and sometimes the rear speakers also. When I accelerate the noise pitch gets higher. I tried messing with the wires to the sub and amps but everything seems nice and tight and I only just noticed it recently.

Does it sound like a connection problem with the amps or something else. I bought the car used and didnt install the system so I honestly dont know much about it. My dad was using the car for about a month before I could pick it up and never noticed the problem and anyone with working ears would notice the sound.

Any help would be great. Thanks
