97 Civic EX. I bought it used with an aftermarket Pioneer CD AM/FM stereo. It had an amp in the trunk but the previous owner removed it before I bought it. All of the wiring is still there but I removed the inline fuse.

Now my problem. Whenever I use anything electrical it causes static on the radio. Turning my fan on causes static. The higher the setting the more static it causes. Plugging my cel phone into the charger causes static.

Any ideas on how to fix this?

 

sounds like the radio in not hooked up properly..i would just take all the wireing for the system out and the deck and redue it all, installing it is very simple and if you need help post something up in the audio part of the forum, im not sure what else it could be..mabey a bad ground? anyone

 

Years ago.. (like 25 or 30) not all spark plugs were resistor type plugs. They were a little higher priced but worth it "if" you had a stereo in your car. Sometimes if you didn't have the good plugs you could hear static in your speakers while the radio was on. This just doesn't happen any more. But, if your static is in any way changing with engine speeds it may be something simple in your cars electrical system. Broken insulator on a spark plug, cracked wires, bad cap, bad ground, etc. If you have some place that's pitch black dark you can open your hood and watch your engine run in the dark. If you have any bad shorts you will see them light up like a Christmas tree, unless it's a spark plug. A bad ground is harder to find. It's easier just to check them. Be sure to check them all especially if you have any under the dash.

Good Luck!!

 

also the RCAs shouldnt be by any power cords

 

^ for signals comming from an amp. Sounds like he doens't have one anymore though.

I'd first try
1) Unpluging the RCA cables from the back of the head unit.
2) Make sure you have a good ground connection.
3) Disconnect the old amp power cable from the battery.

If none of the works you could try soldering a .1uF (micro farad) capacitor between the negative and positive wires of the stereo wire harness. That will help reduce high level noise from the power source.
