Why Did My Car Speakers Stop Working?
Neil Young may keep on "Rockin' in the Free World," but anyone who's ever blown a speaker knows how much of a damper this can put on your next party or air guitar concert. Use these steps to fix a blown speaker and let the good times roll!
Determine which speaker is causing the problem. Use the equalizer on your stereo to shift the balance from one speaker to the other and see where the sound is lost. Make sure to keep the volume low enough that you won't damage the good speaker! Disassemble the offending speaker carefully.
If there is a metal faceplate on the speaker, use a screwdriver to remove it. If it is covered with any kind of fabric, gently loosen the seams without tearing.
Repair a tear in the cone of the speaker. If the cone of the speaker is punctured or torn you can use some tape or glue to repair the hole.
If you are using glue you need to be sure the hole is completely covered. Check to see if the voice coil is damaged. Look at the voice coil to see if it's melted at some point. A gap in the coil will cause no sound to flow or to be very distorted, depending on the size of the gap.
If the voice coil has melted you will have to replace the speaker. Order the replacement parts. You can order replacement parts directly from the manufacturer or from Web sites like US Speaker.
Make sure you know the part number swhich are usually located on the inside of the speaker or backside of the cone.Exhaust fan wire diagram diagram base website wire
Once you have the replacement parts, carefully note how the damaged part is attached. Remove the part and install the new one in the same way. This may require a soldering iron to reattach wires.Cz 457 varmint stock
Hook the speaker up and test it at low volume before your next party. If the speaker is still not working you need to verify that the replacement part was installed correctly.

This is especially true with the kind of lower quality original equipment OE speakers that most cars and trucks come equipped with. Internal components can wear out or come loose through regular use, and there's not a lot that can be done about it. That being said, car speakers tend to fail one at a time. Every speaker in a car audio system dying at once is very unlikely without some serious abuse, like cranking the volume high enough to blow the speakers out.
In order to narrow down the exact cause of this type of car audio problem, some basic troubleshooting is in order. If you are unable to locate any issues with the head unit, then you will want to determine whether or not you have an external amplifier. In-car audio systems that use external amps both OEM and aftermarketthe amp is the most common cause of this type of problem, since the audio has to pass through it on the way to the speakers.
In the process of checking out the amp, you will want to:. Although there are many common car amplifier problems that you can identify and fix on your own, you may run into a situation where the amp seems fine even though it has failed.
When you checked the fade and pan settings on your head unit, you may have discovered that they were set to a speaker or speakers that had failed and that you were able to get sound by moving to a speaker or speakers that work. Since speaker wires are often routed behind panels and molding, under seats, and beneath the carpet, it can be difficult to visibly inspect them.
Depending on your situation, it may be easier to check for continuity between one end of each wire at the head unit or amp and the other end at each speaker. If your speakers are mounted in doors, then a common point of failure is where the speaker wire passes between the door and the door frame.
Although door wiring harnesses are typically protected by hard rubber sheathes, the wires can still end up breaking over time due to the repeated stresses endured in opening and closing the doors. With that in mind, you may also want to check for continuity and shorts with the doors both open and closes.
If you find that one speaker is shorted to ground in that manner, that can actually cause all of the speakers to cut out. Another way to test the speakers, and to rule out bad wiring at the same time, is to obtain some speaker wire and to simply run new, temporary wires to each speaker. If you end up ruling everything else out, and you really are dealing with a coincidental failure, then it's time to just replace your car speakers en masse.
However, you should probably make sure that they weren't blown out by someone cranking up the stereo. It's pretty easy to tell when car speakers blow out if you're there when it happens because you'll immediately notice that they stop working or no longer sound normal.
If it happens when you're not around, and the guilty party isn't willing to fess up, verifying blown speakers takes a little work. The surest way to test whether car speakers are blown out is to disconnect the speaker and check for continuity. If there isn't any continuity between the speaker terminals, that usually means it's blown. Tweet Share Email. Check the volume, fade and pan settings.
Test different audio inputs i. Test any onboard fuses. Check for loose or unplugged wires. Verify that the amplifier is actually turning on. Inspect for loose or disconnected input or output speaker wires. Test both inline and onboard fuses. More from Lifewire.A: It's possible that your receiver is toast, but don't give up hope yet. There are two things to check.RADIO NAVIGATION NO SOUND VOLUME FIX!!!
Many modern receivers have "protection circuits," bits of specialized hardware that recognize dangerous levels of volume and shut your hardware down, like a digital fuse. Some receivers communicate this on the display. Yamahas, for instance, show the word "Protection" on the LCD panel.
Others might display an error code you have to look up in the manual. As long as no hardware was actually damaged when your buddy pumped up the jams, resetting the protection trip should put your receiver back in working order.
The procedure varies from manufacturer to manufacturer, but most protection circuits can be reset by unplugging the receiver, waiting 30 seconds or so for the capacitors to discharge and plugging it back in. Make sure to turn the volume down! As long as nothing is shorted out, your receiver should go back to normal. If your receiver is still on the fritz, you may have blown a real fuse.
Some receivers have a screw-in fuse in the back of the unit that can be removed and inspected easily, while others may have one or more fuses inside the case--you may have to unplug the unit, remove the case and root around inside to see. Normal caveats about possibly voiding your warranty apply, but if your receiver is more than a year old, then the warranty has probably expired anyway. If you find a fuse that looks burned out, it probably is.
Service and Repairs
Replace it with a new fuse of the same amperage and voltage available from electronics parts stores such as RadioShack for about 50 cents a pop and you should be back in business. If, after your fix, the receiver powers on, but then turns itself off after a few minutes, it's possible something is physically damaged inside.
At that point you're looking at a professional repair, not a quick fix at home. Don't use pliers to remove glass fuses--you'll only end up shattering them.
Instead, use a Popsicle stick for leverage.Nonton indoxxi 21
For hard-to-reach fuses, try threading string under the fuse, then pull on both ends of the string to pop it out. Photograph by David Turner. Type keyword s to search. Today's Top Stories.

The fuse that came out says 3. I interpret that as 3 amps and volts.
Package says for electronics etc. Put one in my sub and I get power for about 5 seconds and the new fuse blows. Sounds like a bad amp. Have you had it out yet? You may be able to see a bad spot on the board. Wouldn't have a clue what to even look for.
Not even sure where to take it. The only place around here selling Klipsch products anymore is Best Buy. All the higher end "audio" stores have gone out of business.
Any thoughts on who to call? Would a guitar amplifier service be able to look at it? Or is it simply better to buy another? Thanks klipschfancf4. The original fuse I believe has a thicker wire then the replacements I bought but it is merely my perception and could be totally wrong. I will check the yellow pages. I recall the sub had a burnt smell when the fuse blew - so I suspected it was bigger than just a fuse but thought I would start there.It then gives simple step-by-step instructions for how to disassemble a speaker, how to repair a damaged speaker cone, and how to obtain correct speaker polarity phasing.
Fortunately, speakers are relatively simple in design and can be fixed easily.Musically music download mp3
This guide also refers to other Fix-It Guides for specific repairs. Audio speakers for a home stereo or entire home entertainment system amplify the sound generated from another component of the system. The typical speaker is a collection of complementary parts. The typical enclosure speaker case has a 6- to inch-diameter cone woofer for low frequencies, a 3- to 6-inch-diameter dome or cone mid-range driver commonly called a speakerand a small tweeter for high frequencies.
Audio signals move along speaker cables to a terminal block at the back of the enclosure. Once inside, a crossover network divides incoming frequencies into the appropriate ranges, sending each to the correct driver. Drivers then convert this input into mechanical movement of the cone which, in turn, moves the air in a way that is detected by your ears as sound.
Speakers are most likely to suffer from improper use. The enclosure can be damaged or come unglued. The speaker can blow an electrical or thermal fuse. Wiring can be faulty. The voice coil can be faulty, a speaker can be blown, a crossover network can be faulty, or a solder connection can be faulty.
Cables and connections can be faulty; a driver cone can be damaged. Speakers may not be in phase. Level controls can be broken. All are repairable. Many problems with speakers are actually oopses.
Should you replace the driver or have it re-coned? The answer depends on the cost of a replacement and your budget. Common drivers for low-cost audio systems are relatively inexpensive to replace so you can gamble and try to fix it yourself.
Larger drivers for better audio equipment and musical instrument amplifiers are relatively expensive. Drivers for that classic Fender amp probably should go to a professional service person.
You can buy replacement speakers, speaker repair kits, foam, wire, and other parts and materials at electronic and audio stores. These are other things you may need:. Check to make sure the wires from the terminal block at the rear of the speaker enclosure are connected to the back of the driver.
Want to make sure that the speaker wires are polarized correctly? Clip a wire to each speaker terminal, then touch the other end of each wire to a terminal on a AA or C household battery.
The cone will move out when the two positive terminals are connected to each other. How Does a Speaker Work? What Can Go Wrong with a Speaker? Fix-It Tip Many problems with speakers are actually oopses. One loose speaker wire can stop all sound to the speaker. Unfasten the driver speaker by removing screws around the perimeter.
Can't Find It?Driving your subwoofer loud and hard can usually cause your subwoofer fuse to burn out. Instead, a few simple steps of changing the fuse is all that you need to follow. This will save you a lot of time and money and give you the satisfaction of fixing a simple problem yourself.
Before even replacing a subwoofer fuse, make sure that it is actually the source of your dilemma. Check all connections first, including the battery, speaker wirings and radio. Try to make the subwoofer work normally. In order to replace the subwoofer fuse, you naturally have to find it first. It is usually found along the wires of the subwoofer, near or within the speaker dome itself.E38 pin 40
It could also be found on the dedicated amplifier of the subwoofer. There are two kinds of fuses that you have to expect. One is the usual tube-type fuse, which is about an inch long. This can be found between two connecting wires that should be enclosed in a holder. The other type of fuse is a flat, square, plug-in type. This can also be found at a similar location. When dealing with electrical components, be sure to kill the power before you attempt to change the subwoofer fuse.
This can be done by simply disconnecting the positive and negative terminals of the battery by using the wrenches. Keeping the system wired and live may cause electric shock and could injure you badly. It may also short-circuit the system and do more damage. Now that you have found and determined what kind of fuse you are dealing with, remove the old fuse by either twisting the housing in order to get it open and free the fuse, or simply pull it apart to expose it.
Once the fuse is exposed, simply pull it out. Make sure that the amperage is correct because using a higher one will damage your subwoofer. Hook up the battery and turn on your radio. Play a tune with sufficient bass to check if the subwoofer works and if you attached the subwoofer fuse correctly.
This review comes a little late but then better late than never. Last year we booked the four corners tour of Iceland with nordic visitor. Our trip from day one was very well planned and organised.
Iceland is a beautiful country no doubt but with the services of Nordic visitor it became an unforgetable experience. Here i want to specially thank HELMUR for the promptness in resolving any issues and taking care of all our needs as we were travelling with small children aged 4 and 11.
Must acknowledge and thanks HJULTI who went out of his way to show the best face of Nordic Visitor team. Wish them all the best. I was very pleased with the whole experience. My thanks to Kolbrun who was always quick to reply to my emails and questions. She was very helpful throughout. I liked the hotels selected and the locations they were in. Overall the holiday was a great success and I am sure at some stage we will book another holiday through yourselves.
The map provided to us highlighting the route and where the hotels were located, as well as attractions, was extremely helpful. The itinerary was well planned and we never felt rushed. We really enjoyed your wonderful country.
We asked Alexandra to try to get us the best rooms possible that were also quiet, if possible. It was obvious that she had done so at every destination.
She asked us what we wanted, listened, asked a few good questions and then did her best to find us what we asked for and we were very pleased with the results. The materials provided by Nordic Visitor were fantastic. We used the maps and the brochures and the itinerary and read every suggestion.
The map with a suggested driving route to each of our marked hotels was very helpful. We were very, very well prepared for this trip because of the outstanding work done and materials provided by Nordic Visitor. The trip was planned for us (based on what we wanted to do) and all of the details had been taken care of for us. The route was planned, the hotel reservations were made, we had books and maps sent to us and we were provided with a phone and GPS.
Working with Alexandra was just a pleasure. From the very first email I sent of inquiry about the possibility of booking a trip with Nordic Visitor until the email I sent at the end of our trip asking if we could change our shuttle pickup time at the hotel, she was helpful, knowledgeable, responsive and always cheerful.
Thanks to Alexandra and Nordic Visitor, this was one of the best planned and organized trips we have ever taken. Nothing went wrong, but I have every confidence that Nordic Visitor would have helped us had there been any problems. I have no recommendations for how Nordic Visitor could improve what it does and that is unusual for me. My expectations are high, and they were surpassed. Our trip to Iceland was unforgettable.How to put mercedes in neutral with dead battery
Everything from the accommodations, to the rental car, to the travel documents exceeded our expectations. Jelena was fabulous and truly put our minds at ease answering any and all questions. We were blown away by the beauty of Iceland and the incredibly warm people. Everything was incredible, and we can't wait to return. It was a thoroughly-planned trip from A to Z with many options to select from and add to the trip depending on the location.
The booklets given were most helpful and actually more efficient than Google, or just easier to navigate. Our hotels were perfect.
