If you find the professionals charge a good deal of money to set up the car stereo, you can do it yourself and save that amount paid towards the expert.
It is not very difficult to install a car audio system; it is just that it seems so. You only need a bit of precision and focus to put up the system. No specialized skills or intimate knowledge on car audio is required for this purpose. You can actually put the excess money that you save from the installation process behind the best car audio system itself, thus giving you the scope to buy something better.
While initiating the process, you need to be careful as loss of concentration may lead to the damage of equipments of your car and spoil the quality of the car stereo system. You need to be systematic as the plugs go into their respective sockets only.
• After you purchase a new car audio system, see if it is fitting properly to the place of the old audio system. Along with your new car stereo system, also buy a cabling strap which is mechanized according to the car and stereo model and works brilliantly for new car stereo systems.
• Before you get down to your work, arrange for few tools like electrical tape, wire strippers, screwdrivers and wire cutters.
• If you are not able to unscrew out the old audio system, take some guidance on the right way to remove it from your dashboard where the new car stereo will fit in.
Removing the old car stereo
• At first, detach the negative cable from the battery as you should never work with that cable connected.
• Take out the dash board of your car to remove the old car audio system and check the wires that are linked at the back. Either there would be a single plug with too many wires attached to them or else a cluster of single wires. In case of the later one, it is best to disconnect them one at a time to avoid confusion.
• Put the connectors into the new cabling strap and plug it back into your new car stereo.
If you have successfully done this, you can leave out on the next section.
Connecting the Wiring Manually
• If there is no cabling strap support, attach each of the wires at the back of the back of the new car stereo very carefully.
• Slowly detect the positive wires from each speaker and connect them at the back of the positive connector of the new car stereo. Similarly, do the same with the negative wires of each speaker and connect them to the negative connectors of the car audio system. In case, if there is only one wire coming out from the speakers, the speakers are grounded at the chassis and you would have to install a new wiring for the speakers.
• The negative wire, attached with metal and not plastic should be connected with a screw near the radio in the dash.
• The ignition wires and the 12 constant, both positive is supposed to be connected together to the back of the new stereo.
Putting in the car stereo
• All the wires should be attached to a single connector which is coming out from the additional cabling strap or the one which came along with the car stereo system where all the wires have been connected to.
• If there is no new bracket to place the new car stereo, use the old one that previously held the factory stereo system.
• Now put the final connector which is the cabling strap at the back of the stereo system along with the antenna, a long wire which was previously connected at the back of the old stereo and the power wire at the back of the new car stereo unit.
• Put the stereo system inside the dashboard where the previous system was placed but do not put back the screws as you may require testing the system.
• Now is the time when you should again attach back the negative cable to the battery.
• Start your car as well as power on the car stereo unit. Check keenly, whether all the speakers attached is working fine.
• Put the screws back into the stereo system and put the cover of the dash board back on.
In case results are unsatisfactory
If you still find the system is not delivering satisfying results, you can use a wooden or fiberglass flummox with which the sound quality will get better and you can even include noise reduction objects like liners, glue strips, put in more carpets on the inner panel and use sprays.
