Kako instalirati stereo u autu | Jednostavan vodič za zamjenu glavne jedinice

Instaliranje glavne jedinice ili njezina zamjena može biti teško. Osobno sam potrošio samo 30 minuta na zamjenu glavne jedinice, sve do 4 ili 5 sati za isti posao na drugom automobilu. Postoji niz varijabli koje mogu diktirati koliko je zadatak stvarno težak i dugotrajan:

• Komponente armaturne ploče i obloge – prema našem iskustvu, najteži automobili obično su njemački. Audi, BMW, Mercedes, Volkswagen. Komponente ploče i obloge vrlo su tvrdoglave i čvrste i teško ih je ukloniti.
• Ožičenje – ožičenje se može razlikovati od automobila do automobila. To zapravo ovisi o broju značajki koje automobil ima. Na primjer, OnStar na GM automobilima, ili samo OEM stereo pojačalo. Ovo su stvari koje morate znati prije povezivanja automobila i naručivanja kabelskih snopova za prilagodbu (uskoro ćemo dobiti više detalja o tome).
• Montiranje nove glavne jedinice – ovo može biti posebno teško ako se odlučite za DIY. Međutim, u većini slučajeva naći ćete da postoje prilagođeni 'Dash Kits' od dobavljača kao što su Metra i Scosche koji će pojednostaviti montažu i instalaciju stereo uređaja.

Na kraju krajeva, postoje automobili za koje bih preporučio nadogradnju ili zamjenu stereo uređaja i automobili koje ne bih preporučio. U ovom vodiču nećemo vas samo provesti kroz proces odlučivanja trebate li nadograditi glavnu jedinicu vašeg automobila, već ćemo vas provesti kroz postupak ako se odlučite za to!

Trebam li nadograditi svoju glavnu stereo jedinicu u automobilu?

Prije nego što kupite i instalirate jedan od naših preporučenih najboljih stereo uređaja za automobile ili GPS navigacijskih jedinica, trebate si postaviti sljedeća pitanja kako biste utvrdili DA LI biste trebali nadograditi ili zamijeniti svoj stereo i s kojom vrstom stereo uređaja biste ga trebali nadograditi.

1. Prvo pitanje – Ima li vaš automobil već dodatnu glavnu jedinicu? Ako je to slučaj, vaša je instalacija znatno pojednostavljena jer su ožičenje i montaža već gotovi. Sve što trebate učiniti je zamijeniti ga. Imajte na umu da ćete možda morati promijeniti kabelski svežanj koji se spaja na stražnju stranu jedinice. U ovom slučaju, samo izrežite i uskladite boju žice za boju.
2. Hoće li nadogradnja moje glavne jedinice uzrokovati gubitak značajki/funkcionalnosti mog vozila? Mnoga od novih vozila imaju međusobno ovisne sustave koji se oslanjaju na stereo sustav. Recimo, moj Ram 1500 ima postavke da li se oglasi truba kad ga zaključam, da li se brave automatski zaključavaju nakon određenog vremena, da li svjetla ostaju upaljena nakon što zaključam kamion. Sve ovo kontrolira moja tvornička glavna jedinica. Mnoga vozila to imaju. Ako vaš automobil ima značajke poput ove koje ovise o glavnoj jedinici, preporučujem da zadržite standardni stereo. Ako tražite više zvuka, to možete učiniti bez nadogradnje stereo uređaja.
3. Ima li moje vozilo više zaslona? U nekim slučajevima automobili imaju više zaslona koji su međusobno povezani. Na primjer, na mnogim Hondama postoji glavna jedinica, a tu je i zaslon koji prikazuje informacije iz glavne jedinice poput radio postaje ili CD-a. Zamjena stereo uređaja može zaslon učiniti beskorisnim. Postoje slučajevi u kojima su napravljeni adapteri, trebali biste istražiti jesu li prije nego što odlučite zamijeniti glavnu jedinicu. Ili, ako vam nije stalo, samo naprijed!
4. Zašto nadograđujem stereo u autu? Ako želite subwoofer ili glasnije zvučnike, glavna jedinica nije vaša jedina opcija. Ako želite značajke koje trenutno nemate, poput Bluetootha ili AUX ulaza, tu su i adapteri za to. Ključno je utvrditi je li zamjenski stereo najbolja opcija za vaše potrebe.
5. Koliki je moj stereo otvor? Postoje dvije glavne veličine glavnih jedinica:1DIN i 2DIN. 1DIN je manji od ta dva. Može stati u 1DIN i 2DIN otvore. 2DIN je veći i obično je namijenjen jedinicama sa zaslonom osjetljivim na dodir i većim zaslonima. Evo primjera kako izgledaju 1DIN (lijevo) i 2DIN (desno):

Ako, postavljajući si sva ova pitanja, još uvijek osjećate da je potrebno kupiti i instalirati novu glavnu jedinicu, evo sljedećih koraka!

1. Uklanjanje autoradio

Well, the first step to installing your new head unit is to remove the old! To do this, we recommend you pop the hood and disconnect your battery before anything. This way, you don't short any fuses. Finding a blown fuse can be time consuming and frustrating so take our word that this will save you time in the long run. Once you have done this, start to remove the trim from around your stereo to access the mounting screws. I've found the trim removal instructions from Metra to be very helpful when you do this. In many cases, trim needs to be pulled in a certain direction to prevent cracking or breaking it. Metra does a great job at helping you visualize how to pull your trim off and where. Go to http://metraonline.com/, scroll down to the vehicle fit guide and enter your car. Once you've done this, click on one of the dash kits (this is the piece of plastic that you'll mount your head unit into. It replaces many parts of your trim to make a seamless fit for your new stereo). If you haven't already bought one of these dash kits, we HIGHLY recommend you do. It will simplify your install by 10 fold. Once you've selected one of the dash kits, click on the PDF link under the “Documents” on the left. You'll find full instructions for removing your trim step by step!

Your head unit will be mounted in one of two ways:

1. Bolted to the dash with brackets and screws. This is the more difficult option to removing and where the Metra instructions will be extra helpful.
2. Secured with mounting sleeve and spring clips. For this type, you'll want to purchase our recommended stereo removal keys.

Sticking and Stubborn Dash Trim

It's worth noting that removing trim is probably one of the more difficult tasks in removing your car stereo. You're going to be lucky if you don't hit at least one trim piece that isn't a pain. In these cases, you really want to use a trim removal tool to wedge in between the gaps and gently work your way around the trim piece. Patience is key because once you break a trim piece, there's no turning back. Start in a corner and work your way around the piece.

Once you've removed your trim according to the instructions, dismount your factory stereo and disconnect the wiring on the back of the unit.

2. Wiring Your New Car Stereo

If Metra or Scosche carries a wire harness for your vehicle, we highly recommend purchasing one along side the dash kit. Again, you can use the same link from Metra (www.metraonline.com) to find the one for your vehicle. In the case that you can't find one, you'll need to do a little research on the web to find a list of stereo wire colors on your harness and match them up with the corresponding ones on the car stereo harness. You can find a diagram here of aftermarket car stereo wires. This will help you match the aftermarket up with your factory ones.

If you find that there is a custom wire harness for your car, it's very simple, just match up color for color the wires from your aftermarket head unit harness to your custom wire harness for your car.

Connecting the Wires

There's two options for connecting the wires that you can use:

1. Soldering – For all of the professional installs that I have done I would solder the two together. This ensures a permanent connection that will never short over time. It's more time consuming though. Here's how you do it:
   1. Strip the two wires 1/2 inch back.
   2. (Optional) Place 1 1/2 inch of shrink wrap on one side at least 4 inches behind the end of the wire.
   3. Overlap the two exposed wires and twist the two together until they are interconnected.
   4. Using a soldering iron or a soldering torch, heat the wire and feed in your solder slowly until it absorbs into the wire.
   5. Let cool and test the solder job by tugging on the two wires.
   6. After the wires cool, move your shrink wrap back over the soldered area. If you didn't use shrink wrap, apply electrical tape.
   7. Do this for each wire until all have been connected.
2. Connectors – You can use butt connectors or crimp caps as well. This is a much more efficient way to connect the wires but in many cases I've seen these fail after a few years on the road. In any case, you'll either crimp the two wires together in a clamp by placing the wires in and clamping down on the crimp clam. Or your use but connectors to insert both ends into the connector and clamp both sides.

3. How to Install the New Stereo

Now that your wires are all completed you're ready to install the head unit. Connect all of the wires first. Ensure that there are no exposed wires that may be in contact with any part of the vehicle. We recommend connecting your battery and testing the stereo out prior to fully installing it back into the dash.

Once you've tested it (and it works!) you'll want to add the mounting brackets to your new head unit. If you have a dash kit, use the ones that come with the kit. If not, use the ones off of your factory stereo. If you have the dash and mounting kit, follow the instructions in the manual. If not, you'll need to test where the new head unit sits, and adjust your factory trim to make it fit. This is normally a difficult task. I'd recommend using a Dremel to make cuts and adjustments to the plastic.

Slide the stereo into the opening in the dash, ensuring that the wires behind are tucked and not pinched. Sometimes this may take a few times when the vehicle has a tight dash opening. Tuck the wires back into an opening behind the unit.
