Zašto se moj stereo u autu zagrijava? 5 jednostavnih načina da to popravite.
Ako se vozite na kratke izlete u trgovinu ili imate duže izlete na plažu, jedna stvar koju ćete sigurno koristiti je vaš stereo u automobilu.
Slušanje glazbe, podcasta ili čak puštanje DVD-a za djecu zahtijevaju da imate sustav koji glatko radi. Pronalaženje zašto se stereo u automobilu zagrijava jedna je od najvažnijih stvari o kojima razmišljate.
Uređaj vašeg automobila može se pregrijati iz mnogo razloga. Najčešći su neispravno ožičenje, ventilacija i stereo uređaji niske kvalitete. Svaki od njih će imati različite ukupne učinke na to kako ćete uživati u svom stereo uređaju na kratkim ili dugim putovanjima. Da biste ih popravili, morate stvoriti okruženje u kojem će stereo uređaj imati dovoljno ventilacije i pouzdano ožičenje.
Jedna od najstrašnijih stvari koje ćete naučiti o stereo sustavima u automobilu je da se mogu pregrijati i izgorjeti vaš automobil čak i ako ga niste koristili nekoliko dana.
U članku u nastavku objasnit ćemo zašto će se vaš auto stereo pregrijati i što možete učiniti da spriječite pretvaranje vašeg omiljenog cruisera u ništa više od hrpe pepela.
Što može uzrokovati pregrijavanje moje glavne jedinice?
Postoje tri glavna razloga zašto će se stereo u automobilu pregrijati, a svaki zahtijeva drugačije rješenje.
Znati što su oni i kako ih pronaći prvi je korak u pronalaženju trajnog rješenja za vaše probleme sa stereom u automobilu.
Ako počnete primjećivati čudno ponašanje stereo uređaja u automobilu, onda su ovo tri stvari na koje morate obratiti pozornost:
Nedostatak ventilacije
Svi elektronički uređaji trebaju ventilaciju, osobito oni koji nemaju ugrađene ventilatore. Ovi sustavi i dalje će imati otvorene dijelove gdje topli zrak može izaći, a hladniji zrak može brzo ući.
Isto se može reći i za automobilske stereo sustave, pri čemu jači sustavi zahtijevaju složenije ventilacijske sustave kako bi se uklonila sva stvorena toplina.
Većina stereo uređaja za automobile trebala bi biti otvorena s najmanje dvije strane, pri čemu su nosači za montiranje jedini dijelovi koji dolaze u izravan kontakt s glavnom jedinicom koju ugrađujete. Ako sumnjate da vaša glavna jedinica nema dovoljno ventilacije, trebate je ukloniti i provjeriti područje za montažu. Odavde biste trebali moći lako vidjeti kabele koji prolaze ispod upravljačke ploče.
Loše ožičenje
Ponekad vaš auto možda i nije najljepša stvar na svijetu, a svaki član vaše obitelji vozio ga je prije nego što ste ga dobili, ali čini se da vaš novi stereo radi dobro.
Ovdje počinje najopasnija vrsta pregrijavanja audio sustava automobila; neće svi kablovi u vašem automobilu biti iste kvalitete. Ako koristite žice koje daju preveliki napon ili ne mogu podnijeti traženu količinu, doći ćete u opasnu situaciju.
Da biste testirali kabele koji ulaze u vaš auto stereo, morat ćete ih provjeriti, i ako se neki od njih pregrijao, vidjet ćete da je plastična izolacija slomljena, otopljena ili samo spaljena.
Osiguravanje da se vaš stereo sustav ne pregrijava zbog lošeg napona koji prima može vam uštedjeti mnogo vremena i glavobolje.
Kvaliteta stereo jedinice
Mnogima je najteža pilula za progutati to što je problem u povoljnoj marki stereo uređaja koju su kupili za svoj automobil.
Ljudi će se često htjeti držati najjeftinije marke kojoj vjeruju kada rade prve nadogradnje svog stereo sustava; ponekad je proizvođač automobila učinio isto.
Ovi sustavi niske kvalitete obično nude iste pogodnosti kao i skuplji stereo sustavi za automobile. Međutim, oni rijetko pružaju istu razinu istraživanja, uzrokujući pregrijavanje stereo sustava čak i kada ga vaš klima uređaj hladi.
Kupnja skupljeg stereo uređaja ne znači samo dobivanje kvalitete robne marke. To znači da vaš stereo uređaj neće uskoro zapaliti vaš automobil.
Kako ćete znati je li auto radio vruć?
Za razliku od računala koja će vas upozoriti kada se pregriju, stereo sustav obično radi sve dok se ne pokvari ili izgori automobil. Ako naučite kako mjeriti toplinu stereo sustava u automobilu i nalazi li se na opasnom području, to će značiti da možete sa sigurnošću vjerovati svom novom stereo sustavu.
Postoje samo tri načina za mjerenje temperature stereo sustava u automobilu bez instaliranja skupih i prekompliciranih sustava za nadzor temperature.
Dodirnite Stereo jedinicu
Ako sumnjate da se glavna jedinica pregrijava tijekom korištenja, najjednostavniji način da to provjerite je da stanete negdje i dodirnete je. Ako je prednja ploča uređaja vruća na dodir, to može biti znak da nešto nije u redu. Mnogo puta, ovo je trenutak kada biste trebali ukloniti radio što je prije moguće.
Kada jedinicu uklonite iz automobila, možete je priključiti i testirati jednostavnim uključivanjem sustava i pokretanjem vozila. Puštanje nekoliko pjesama i uživanje u glazbi s uklonjenom jedinicom trebalo bi proizvesti isti učinak. Ako se radio ne zagrije toliko i možete ga dodirnuti, problem je u ventilaciji.
Grija li se radio brzo?
Kao što je ranije rečeno, sva elektronika proizvodi određenu razinu topline, a stereo sustavi automobila trebali bi se zagrijavati dok ih koristite čak i za najopuštajuće vožnje. Međutim, trebalo bi proći dosta vremena dok jedinica ne postane primjetno vruća na dodir i nikada ne smije biti toliko vruća da je ne možete dodirnuti.
Ako se vaša glavna jedinica toliko zagrije da ne možete čak ni promijeniti glasnoću a da ne opečete vrhove prstiju, to je jasan znak da nešto nije u redu. Trebali biste odspojiti stereo što je prije moguće i provjeriti priručnik za moguće uzroke. U nekim ćete slučajevima možda morati poslati stereo uređaj na popravak.
Uključivanje i isključivanje
Iako se dodirivanje stereo jedinice može činiti kao najčešći način da vidite grije li se vaša glavna jedinica, to obično nije prvi simptom s kojim se susreću vlasnici novih automobila. Ako imate kvalitetan radio poznatog brenda, on će imati sigurnosni prekidač.
Ako se jedinica pregrijava iz bilo kojeg razloga, ovaj sigurnosni prekidač će potpuno isključiti stereo sustav. You will not be able to restart it even if you shut down the car and start it back up, meaning it is the best and safest way of seeing if your vehicle is overheating or not.
The stereo system manual will usually tell you that this is why the stereo worked fine for a while and then suddenly shut down.
Are Overheated Car Stereos dangerous?
Overheating car radios are one of the most dangerous parts you can find inside of your car. They can cause instant fires and not only while driving but also for vehicles parked in your garage. Car fires are some of the fastest and most intense types of fires you will ever experience.
There is one universal truth when it comes to the heat in the car, and the only part of the vehicle that should be extremely hot is the engine. Well, there is one more, and these are brakes, but we are talking here about car interior.
Every other part of the car should be warm or cold, depending on how you set the car’s air conditioning system.
When you are installing a new radio system, you may be wondering what is the worst thing that could happen to your car.
The easy and simple answer is that it will burn down, even when completely turned off. An overheating custom stereo system is one of the most common reasons cars are suddenly going aflame.
How do I prevent car radio from overheating?
When you have done all the testing and finally figured out that your car stereo is indeed overheating, you will want to find a way to stop it. There are many solutions to consider, and some of them are as simple as doing a few wiring problems, while others require a few days of work to make it correctly.
Knowing what each option is and how you can effectively implement them without a challenge will mean a lot less stress for you overall. These should be done starting with the most evident and important, moving down to the expensive and complicated.
Check Harness and Wiring
Any head unit’s wiring is the leading cause of them overheating, so when you get a used car with a modified stereo system or install your own stereo system, you should do it to the best degree possible. Before you start working in your vehicle, you should have the new stereo system in front of you, along with its instructions.
Reading these will tell you the thickness of the wires required and the voltages the unit will pull while working. Checking to see if your car’s wiring harness will handle these is vital to preventing damage later down the line.
If you are receiving a car with an already customized stereo system, you should remove the stereo system to check whether there is any wear and tear on the cabling harness. Usually, if there is some damage done to the wires, the insulation will have turned brittle or become discolored. Replacing wires that are damaged with stronger ones will mean you can comfortably keep using the stereo system.
Improve Venting
The other thing that is likely to cause heating to go out of control on your stereo system is improper heating. If you have a standard stereo system, then the mount in the car should already have the required venting holes to ensure it does not overheat. When the stereo system does require extra venting, creating them is not as complicated as you may think.
The mounting unit for stereo systems in all cars is a mix of plastic and metal. By removing some of the plastic, you can create extra passive ventilation.
The plastic you can cut easily by using a Dremel tool or a small metal saw. It will be a tight space to work in, but once the right ventilation holes have been created, your stereo system should work a lot better.
One of the most overlooked ways of creating more ventilation is tidying up the stereo system cables. Using zip ties and a few creative bends, you can ensure that the airflow for the entire dashboard is improved tenfold.
Both of these should be done if you ever suspect the stereo system needs a bit more air to breathe.
Cleaning Around the Stereo
To the surprise of many new car owners, the car’s inside can become surprisingly dirty if not cleaned properly. When you are checking on your stereo system or installing a new one, it is always good to do a bit of extra cleaning around the dash and clean the stereo.
Using compressed air and a soft brush will clean out all of the dust that can become accumulated in the nooks and crannies of your car. This simple addition to checking on everything in your vehicle will improve the car electronics’ overall performance.
The best part about this step is that it takes only a few minutes to complete and will help solve the venting problem. Some of the dustiest places on earth can be found in the nooks and crannies of the dashboard of any car.
Add Cooling Fans
An extreme way to keep your stereo system cooled is by installing a few basic computer fans into the dashboard. These fans are created to operate for hours on end without resting or needing to be maintained, and if you are unsure if the vents for the stereo will be sufficient enough, you can simply add these.
Computer fans have been the most popular way of fixing the overheating problem for stereos for a long time. This is because the car’s internal wiring provides the same voltage and amperage as those found in computers. Many larger stereo systems will already have some of these included or mounting locations for fans.
However, it should be noted that while computer fans can quickly help to prevent overheating for a stereo system that needs more venting, the fans can cause more problems. An exposed fan in such an enclosed area with cables can be hazardous. It should only be considered a solution if you are entirely comfortable with your car’s internal wiring.
Replace Stereo With the New One.
While venting, fans, cleaning, and new wiring are all ways of easy fixing your overheating stereo, sometimes they will do nothing other than prolong the inevitable. If the previous owner of your car installed a low-quality stereo system or you decided not to get a proper system, then it will eventually fail.
Stereo systems do not always have to go through diligent testing or requirements set out by the government. This means that when you buy a cheaper, budget stereo from an unknown brand, it could have several faults. These systems usually draw too much power, are not well cooled, and have a power draw that can kill your battery.
It may seem counterintuitive, but buying lower functionality, higher quality stereo systems from trusted manufacturers will mean years of saved headaches. A proper stereo system will have warranties, be quality assured tested, and adhere to several operational guidelines set out by governing bodies.
Zaključak
The fight to have a proper stereo system is a never-ending one, and ensuring that it works properly in your car is a simple series of steps that you need to follow. An overheating stereo system is one of the most dangerous things you could have in your vehicle. It’s better to drive around without sound if it is overheating.
Just be sure when you install the new stereo system that you connect the speakers correctly. Nothing says botched job like no sound from the right and scrambled squeaks from the left!
