Car Speaker Repair: How to Reduce the Hissing Sound in Car Speakers Car Speaker Repair: How to Reduce the Hissing Sound in Car Speakers
When you hear a hissing noise coming from your vehicle, there is a simple car speaker repair trick you could use to solve the problem. Have a friend adjust the settings on the vehicle's radio as you listen to each speaker to locate the one that is having the issue. You'll then be ready to investigate and apply your fix.
Step 1 - Remove the Speaker from the Housing
Before you can do the car speaker repair, shut off all power to the vehicle to prevent electrical shock, and then use your wrench and screwdriver to get the broken speaker out of the vehicles housing. Carefully disconnect the wires from the back and mark the black wires connection on the speaker with your marker to ensure it gets reconnected to the correct side one you reinstall it.
Step 2 - Check the Speakers Cone
once you have the speaker out and disconnected from the vehicle, look at the top side of the speakers cone. During this car speaker repair you are going to look at the cone carefully for fine rips or tares in its surface that may be causing the hissing or static noise in your output. If you locate a rip or tare, simply apply a light film of glue or a sliver of tape to seal the rip closed, this will prevent the noise which is coming from the edges of the rip vibrating while in use. Let it set or dry for 30 minutes and then reinstall it into your vehicle in reverse steps.
Step 3 - Check the Wires and Magnet
If you have not seen any rips or tares during the inspection of the cone during the car speaker repair, the problem could be electrical feedback, which can be caused by wires or the units magnet. Look at the bottom of the speaker where the magnet is and double check that the wires are not grounding out on anything and are not frayed or broken.
If the wires are not connected as they should be, you can attempt to solder them back on with your soldering gun, or even wrap wires in electrical tape as needed to ensure wires are not shorting out. If the magnet is rusted out or the wires are damaged beyond repair, you will want to replace the entire speaker unit, being sure to get the correct amperage for your vehicles system.
Step 4 - Double Check the Harnessing
The only other thing you can check during this car speaker repair is the wires as they run from your speaker into the harnessing of the vehicle itself. Be sure that these wires are not cracked or frayed and are not shorting out on metal in the frame of body around the speaker housing in the vehicle. If all of these things have been checked and show no visible signs of damage, you will want to replace the entire speaker with a proper replacement that matches your vehicles stereo output.
