As you can probably already tell, I am really into my car audio. Car audio is what I enjoy doing on a daily basis and I have learned a lot over the years. I used to be a car audio installer for the last 10 years and now due to the local car audio shops closing down in the UK, there are not many jobs going. Thankfully, the internet has given the ability to still share my car audio top tips to ensure you guys are still getting the best sound from your car audio systems. I have built several car audio systems over the years, I have done everything from building my own custom made subwoofer enclosures to making custom door panels with many car speakers inside. Today, we are going to discuss why your car speakers are crackling, what can cause this annoying problem and ways potentially that you can consider yourself to fix your own car audio system.
The first thing you need to rule out is it the source of your music? Is it a poor recording of a song? Are you listening to an CD is it scratched is the aux wiring you using damaged or poorly made? Are you using a cheap bluetooth to radio adapter to get a bluetooth connection on your car stereo? You need to first rule this out, once you have done so, then you will know it’s the source of the music that contains crackling or if it actually it the car audio system within your vehicle that is falling?
Crackling usually means a bad speaker connection somewhere. This can be anything from the back of the radio wiring loom on your radio right to the connection on each speaker inside each door. It could be a fault with the internal amplifier if you have a factory bose or similar system. Do you see any nicks or cuts in the speaker wire? Do the radio plugs look loose on the back of the headunit? These are the things you need to look for.
If you notice that the crackling is only coming from one side of the car, pinpoint if it’s coming from the front car door speakers or the rear car door speakers. Sometimes, it can come from any side. If you find which car speaker it is coming from, that will then allow you to get closer to fix the crackling car speakers problem. You can then remove the speaker and test another speaker in its place to see if the common car audio problem has been fixed. If the crackling still happens with the replacement speaker then add new car speaker wire to it, directly from the car speaker to the rear of the radio. You will find many wiring diagrams online to find the correct speaker channel on your wiring hardness on the back of the radio. Chances are the speaker wire may have become degraded from wear and tear. This can happen over the years from opening and closing the door, overtime it can break the copper inside the wire, the rubber door boot you find in between the car door and car can only protect the wires so much.
If you still notice that the car speaker are crackling, then the amplifier within the headunit is not working correctly. The mosfet transistors may have become bad overtime, which is normal as all electronics eventually degrade and need repairing or servicing. But in this day and age, its better to get yourself an aftermarket headunit from good car audio brands such as pioneer or kenwood and swap it with the factory headunit. You may need an aftermarket headunit panel, radio adapter and wiring loom for your vehicle as it may not power on.
If your struggling to fix the car speakers crackling, sometimes it’s easier just to totally remove the factory car stereo system from your car and replacing everything with aftermarket parts. Get some good quality speaker from JL audio, get a 4 channel car amplifier and an good quality headunit from pioneer or kenwood. You will need an 8 gauge car amplifier wiring kit and about 20 meters of car speaker wire on an roll, so you have enough to run across each door. This will certainly fix the problem and you might find it less time consuming and stressful by just starting with a new car audio installation.
