I really have two questons. the first is that the light of the panel on my stereo is always on. whats that from? the other is that i have a sound system in my car. i know its the head unit. when ever my...


Hi There. This may be line noise.

Check that your head unit and amplifiers etc are all earthed to the same earth. ie: If connected to the battery earth then connect all earths to battery, or if connected to body earth then connect all to body earth.

Another thing is to check that your RCA Cable or interconnects are not running with your power wires. This can induce line noise.

If all is correct then get yourself a noise suppressor or a ground loop isolator.

Hope this helps

Im trying to install aftermarket stereo


it is located behind the stock stereo up in the back farther and it look like a black box. The wires depend on the radio but if its a cd player go to like walmart and look at the radio wire harnesses and look for the one that'll work for your vehicle

Hi Theaternut,

 

Best guess is that your source button or whichever button changes from cd, to Tuner, to usb, to Card, is shorted, and needs cleaning.  Its like the button is always pushed.

 

see if you can carefully dsiassembly the reciever to get to the circuit board behind the button I speak of, and clean it.

LED turns on, but power light doesnt and there is no sound coming out of it.


it sounds to me like you have a bad ground or a short in the ground wire. try checking the ground cable as well as theremote wire (blue), and make sure the ground is connected to an unpainted,clean surface such as the frame of your car.
