There are numerous ways to fix car speakers against many of the traditional and standard problems and the issues, but there it got the specific one which seems somewhat impossible to repair; if you are the one like myself fiddling around to figure out how to fix a blown car speaker, you are saved!
Luckily, I had gotten some tweaks up and sorted that enabled me to fix the blown car speaker, but if you do not really know NOTHING about it (even the indicators that tell the speaker is all blown, do not do it yourself, i.e., run into DIY NOT before learning the exact steps and the process that would enlighten you with all the indicators, repairs, and the ways to get it fixed through DIY and with all the professionalism.)
Out of the reasons, the overpowered transmission right from the batteries towards the speakers is known to be the common cause of the blown car speakers where it triggers to deform the woofer and leads to noise and distorted sound to emit out.
But that is not all of it; the damaging effect does not happen at once, but it takes a lot of time to get to know whether the speaker is all blown when it turns serious.
In general, people tend to purchase newer car speakers instead of repairing the damaged ones while it seems feasible to do so. And when it is, do not waste your time to get the newer one installed up in your car.
How Can You Tell If a Car Speaker is Blown?
First off, knowing if the car speaker is really blown is a tricky task, but you have to learn it is all gone.
To know it better, do the following;
- Sound distorting, causing the fuzz and hissing
- Rattling or telltale popping instead of the music
- The break of treble, mid-tones, and lack of bass
- No to little vibration from the speakers
A little technical touch to check if the car speaker is really blown
Even though if you are not sure with if the car speaker has not been blown out and demand to check for it, do the following of the technical process to follow;
And the only way is to check for the continuity, and nothing can really tell if the speaker has been blown out or not.
- Remove off the speaker grille
- Take off the door panel in order to access the speakers.
- Disconnect every single speaker wires
Now, bring the multimeter to check the continuity between both speaker terminals and whether the multimeter shows no continuity than it indeed indicates the speaker is gone and blown.
Volume does not tell the speaker is blown, ALL THE TIME!
Sadly, the volume is NOT an epicenter of the issue that details the speaker is gone and blown for you.
While it seems really simple to hit the speakers running with the high volume for prolonged periods, that is NOT just a reliable indicator; the speaker is really gone.
Clipping from the amplifier, physical damage, and a number of countless causes can actually cause the blowout to happen.
Generally, the clipping does sound like a blown speaker, but it is not as it mainly causes due to the amp being overdriven in the performance with the tops and bottoms of the audio waveform that are clipped off for you.
So, whenever the clipping happens, it could occur due to the speakers getting damaged because they are designed actually to handle more power than the amp’s rated one.
As with the physical damage at a time, the speaker is carelessly installed, and the protective grills come loose where it could not get immediately replaced. And when you do not have the protective grill, or the cover put on, anything could get the speakers damaged by piercing or tearing the cone as they are the first and the delicate object that cannot withstand any sharp tools.
So, you got the speakers without any sort of cover, and we dearly advise you to get them covered as soon as possible before the damage occurs.
How to Fix a Blown Car Speaker
Okay, once you are 100 percent assured the car speaker is all gone and blown, the only way is to revive it back by fixing it, but how to fix a blown car speaker, you do not have to win an electrical engineering degree to run all the fixations.
Totally outdo to perform at the DIY level, let’s follow the process that we are about to offer to follow by heart;
1. Removal of speaker
The first step is actually to remove the speakers, and that is what everyone can do without a little guidance.
- Get the screwdriver to remove the mounting screws.
- Now, get the enclosure opened from all sides.
- Put the power supply off, for GOD’s sake.
- Final step; disconnect the wires from the speaker before you leap over the next step.
2. Removal of the surround
No, it is not the surrounding system, if that is what you are thinking but the foam surrounding that used to wrap the speaker. 🙂
The easier way we suggest is to get the knife to stab over the old foam to produce a little hole around while gradually tearing the surround using your hand. But be super careful not to tear or break the paper cone OR get ready to withstand the more damage than only fixing the blown speaker.
And the second and the safest route to follow like the step one; bring the knife and stab a bit on the old foam surrounding the speaker, then cut it out gradually through a scissor, which results in completing the whole step quite safely without damaging the paper cone.
3. Removal of the cone TO everything
Now comes the turn of removing the speaker’s cone first, and that is by using the knife again to scratch the cone from the edges.
The removal of the voice coil that is connected with the speakers. But way before doing that, take the terminal wires disconnected first or if they are mistakenly cut off, get ready to run into a bigger mess than anything.
Finally, we reach the point to get rid of the old glue remains. It is relatively easier to wipe completely off the speaker from the remains of the old glue by either using the knife or sandpaper’s back to scour it off thoroughly and completely.
4. Cleaning time (of the speakers)
When all of the components are out, let’s bring the soft cloth to wipe out any dirt particles from both the speaker’s center and from the edges to get them cleaned in full. For the efficiency and keeping the cleanliness to the max, get the compressed air cleaner that massively assists in blowing away all the dust in a single blow.
5. Get the new voice coil
Let’s first bring the new voice coil to assemble over the speaker to the installation phase.
First, get rid of the old voice coil by replacing it with the newer (brand new) one by putting it back onto its desired position where you had the old coil removed from. Do not miss to get it placed from a centimeter away, or it would mess up the sound quality.
6. Get the new speaker cone to install
Then comes the turn of the new cone to sit over the voice coil. But to proceed with it, get the adequate volume of the glue applied around the edges of the new cone first and wait for up to a minute or two to get it dried up.
7. Time for a new surround!
Like the old one you removed from the speaker, the new surround would go into the same position just like the old one.
Then again, apply some glue over the cone and wait for a couple of minutes to get it thoroughly dried.
8. Now, install back the speaker to your car
What’s new in that? Mount the speaker to the place you got it off by actually mounting the screws using the screwdriver and then connect all the wires back into it. Forget not to leave any of the cables unhooked to the speaker once it is fully installed.
9. Testing time!
And the testing here means you should not have the volume fully raised with the bass turned up to its extreme.
Blow the test at the relatively lower volume first.
When you hear the sound emitting out without any problem, increase the volume gradually.
Now, you are good to experience up to 70 or 80 percent without listening to the distortion or rattling causing into the sound as well as the speakers are performing and have been equally vibrating — voila! YOU ARE SO DONE!
Conclusion of how to fix a blown car speaker
Here we jump to the conclusion of how to fix a blown car speaker even if you do not possess any sort of technical knowledge about it and even if it is your first time doing such a fix.
So, do not take it extraordinarily seriously as it does not sound too complicated of a task and allow anyone to repeat it by simply following…. What? Of course, we detailed the whole process to ensure you do it just like any professional does with accomplishing the desired results (the real fix) without seeking any sort of assistance!
