My car stereo makes a static noise. i have to push it in or wiggle the stereo around and it sometimes stops and sounds good. but if i turn on my car or drive over a bumpy area the stereo starts to make loud static noise again. one person told me that because its a detachable face stereo that its not making proper connection. could that be it or something else?
I had a static/hiss sound coming from one speaker on my Sony head unit. The stereo was brand new and had just installed it. The stereo that it replaced had no static. Turns out it was the input setting on the separate amplifier being too high. The stereo has 4 volt pre-amp outputs.

Sounds like oxidized contacts.
If volume is a turn-knob, then wiper-track (inside potentiometer) is worn.
If it's a PTM (push-to-make) standard button, the button contacts may be dusty/dirty/oxidized.
buy a contact cleaner such as Servisol,
and squirt liberally to wash out any gunk.
Move/press/wiggle scratchy one to help 'scrub' the contacts clean.
If this doesn't help try have control replaced.
You might cure this with inline suppressor which you connect somewhere between aerial and input jack.if it makes static noises when engine is not running then it is an aerial issue.either the input is not pushed all the way in or the braid is touching metalwork or the cable is faulty.
My car's glovebox door/trim was rattleing makeing a static noise. I had a friend push up on the trim while it was making the sound, and it stopped, so I just jammed a small wad of tissue up between the trim, and that solved it for the time being. Funny thing tho, after I had my tires balanced, the noise went away never to return. You could have a faulty blower motor tho, if the tissue don't work, or you can't stop it by applying pressure to the trim, look into blower motor replacement.
Don't worry, it's more possible that you have the static electricity and through your stereo this electricity goes to the ground. Try touching another metalic surfasce (refrigirator, oven etc), try to change your shoes (especialy if your stereo is on a carpet floor and you walk on it) Sometimes when we are very nervous the static electricity on our body is higher. So keep calm.
The sound chip may have gone in the stereo, especially if someone has had it on very loud they sometimes blow, otherwise you have 2 speaker wires touching each other, that way you only get static noise, insidee the door they sometimes come free and touch the body
shut down all electrical sets around and check if the static goen the problem will be in electrical sets and you have to check it one by one.if it is not solved check your cables for any bad connector -open circuit- short circuit(try with a couple of new cables).-apply a contact cleaner in all sockets and move jack in and out in all sockets(with no power on)
The first thing is to make sure the speakers are bad. You can seitch them around from side to side if only one of them is bad, if the one speaker still has bad sound, thats your problem. You can also test the woofer of the speakers. Just push in on the woofer with your fingers to move the woofer in and out (with the stereo off). You should here nothing, if you do, the speaker is bad. If both speaker are bad, expecially if they went bad at the same time, the stereo is bad, expecially if you are getting the static with the stereo on and the volume all the way down. Going buy your problem I thing that your stereo is bad. It will need tobe repaired.
