first of all,do u have the strip wire in the red which is the hot side of the sub,next if that doesn't fix it u need to change ur spark plugs they will interfere when the engine is running,so call ur local auto parts dealer and ask for spark plugs that don't interfere with the radio.Hope this helps
Chances are there is nothing wrong with the mixer. IF you accidentally turned on Phantom power, that would cause the problem. Phantom is ONLY used with condenser mics and a few DI boxes. Turning it on can create noise unless balanced lines are used everywhere.
When starting the bike, the starter relay pulls in to divert power to the starter solenoid. To insure that the solenoid gets all the power it needs, the accessories on the bike are turned off momentarily. Once the bike is running, they come back on. The "crackle" sounds like it might be interference from something on the bike, nothing wrong with the speakers or it would make the sound all the time. It's probably pickiing up the impulses generated by the speedometer or something when when the bike is moving but is not doing anything when you're standing still. A dealer may can find it or you can disconnect various accessories and take a ride down the road to see if the interference stops. Once you determine what is causeing the interference, then you'll have to figure out how to stop the interference from affecting your speakers.
A possible cause for the static in your cordless phones could be dimmer switches around the area of your phone that causes static. Turn the switches completely off (not just turned down) and see if the static leaves. You can replace the dimmers with regular switches if that clears your static. If it does not, another trace for interference: you will have to take a portable radio and turn it to AM 550 mHz and tune it to the loudest crackling noise. Carry the radio around looking for the loudest static interference. Could be a loose connection in a receptacle or panel box. Any small malfunction can cause static on wireless devices.
To stop the
crackling sound, you need to remove all of the dust particles from the wire in
the back. Sometimes when the unit is extremely dirty you can see sparks emanating
from the wire, this is what causes the crackling sound. The unit has a built in
cleaner you can lift up and down to perform this task, located on the top, but
this doesn't work extremely well.
I usually take a can of compressed air and blow as much of the dust I can off
the wire and all surrounding internal areas as I can. This along with a
thorough cleaning of the blades should eliminate the crackling noise. Of
course, make sure the device is unplugged before performing any cleaning.
Not sure about the smell though. Mine has started to smell a little strange and
I haven't figured out how to fix that problem.
there seems to be interference via sound as the picture is fine. the interference is a crackling noise& tv is old
