Beginner's Guide to Car Audio Installation - DIY

!: Beginner's Guide to Car Audio Installation - DIY

Speaker Positioning

Speaker installation is very critical for performance. Whether you spent 00 or ,000 on a set of speakers, if they are not properly installed, they would not sound as they should. Even though it may seem that the best position for most speakers are in the stock housing's that came with the car e.g. on the door panel near your feet, this is just not so. You would see why such positions are still used however along with alternative solutions such as center channels for 5.1 dolby, LCD screen, in-dash DVD players. There are many factors that need to be considered in placing the speakers in the correct position.

Distance

The first thing to consider is distance. If the left speaker is only a couple feet away from your ears, while the right speaker is several feet away from you, then the sound will arrive at different times giving you poor sound. Since the left speaker is closer, it sounds louder. The best solution is to figure out a location where the difference between the distance of the right speaker to your ears and left speaker (also known as path length difference), are minimal. This is where kick panels become the preferred location.

Multiple Speaker Placement

If you have a system with two or more speakers per side, you need to try out different locations to obtain the best possible sound in your car. If you have a 2-way system with a tweeter and sub per side. The subs are mounted in the stock location at the bottom of the door. The tweeters are mounted high up on the front corner of the door panel. From the driver's seat, you can see that there are 4 speakers all aimed towards different orientations and all at a different distance to your ears. This interaction of sound waves at different frequencies arriving at your ears at different times seldom sounds good. The best thing to do is to position the woofer and tweeter on each side as close as possible to each other. This is also why kick panels are used so much these days. Professional installers do use some tricks such as inverting the tweeters' polarity when mounted for example on top of the dash while the woofers are low. Achieving good sound with unconventional mounting schemes is very, very hard and is only achieved after plenty of time has been spent trying different configurations.

Aiming

Our ears can distinguish the direction of sound more easily at higher frequencies. This means that aiming the mids, and most importantly, tweeters towards your ears play a critical role in sound imaging. Midbases are not so critical, but should be also aimed towards the listener's ears if possible. To figure out the best aiming angle involves many hours -even days- of work. To start, try to aim the speakers towards the center of the car. Play around with different angles until you obtain the best sounding position. Subwoofers should be mounted up front for best sound. Since this is not possible in most cars, mounting subs in the back is not such a bad thing, since most people can't distinguish where bass comes from. If you have good midbases going down to 60 Hz or less and subs picking up the signal below 60 Hz, then the bass will seem to come from the front.

Enclosures

Subwoofers need a properly designed enclosure to give top performance. Midbases and mids also do sound much better if they are installed in enclosures. The best sounding and easier to build enclosure type for midbases and mids is sealed.

Mounting Speakers

If you are using speakers that fit into the stock location, make sure there are no spaces or holes. Sometimes building a wood or fiberglass baffle helps reduce holes and gives you much better sound. Always be careful when using power tools around speakers. Holes in speakers usually are not covered by the warranty. For unconventional speaker locations, sometimes metal has to be cut. If you have the resources, plasma cutters and pneumatics tools work great. For most of us that do not have these tools, a pair of metal snips (left and right cut) will do the job.

Take your time to plan your system and dont just buy brand and product for the sake of popularity. Sometimes the simplest system is the most effective.

Car Monitor Installation Explained

One of the most important things that you will need to contemplate before even attempting to install a regular car DVD Monitor, or perform a challenging headrest Monitor install, is what type of tools will be required for the job. Even though each vehicle and each car Monitor system is different there are still some fundamental items you will most likely need to successfully complete the car Monitor installation process. The majority of projects you will require needle nose pliers, a flat head screwdriver, a Philips-head screwdriver, and a combination wire crimp and strip tool. Other tools to consider are a panel tool, utility knife, ratchet/socket set, drill/bit set and a torque driver set as well. Keep in mind that this is only a short list of the more basic tools that are needed and numerous other tools may also be needed as you proceed with your install job.

Firstly, you need to begin by thoroughly reading the instructions and make sure to study any schematics supplied with the car DVD monitor to make sure you completely understand the whole process of successfully installing it properly.

Dvd Player Audio Car Headrest

Even though there are many makes and models of car DVD monitors on the market, they are still usually composed of 3 essential Components. These include the DVD player itself, the LCD or TFT monitor, and the audio system. Furthermore, you will need to understand that there are 4 main different types of installations that will cause you to experience 4 varying degrees of difficulty.

XO Vision's GX2148 sports a 9-Inch Wide Screen Overhead Monitor with Built-in DVD Player, USB and SD Card Inputs and an FM Transmitter for playing Mp3s on your stereo system.

They are as follows:

2 DIN Car Monitor System

The term 'DIN' is actually an internationally accepted standard for in-dash car multimedia units. The number 2 in front of the DIN basically means that it is a standard double deck slot size.

This particular type of system is mounted into the dashboard of a vehicle and will most likely make it slightly more difficult to install, especially if you are attempting to do it from scratch. Since a double DIN car monitor system contains the largest and most aesthetically pleasing screen for your entertainment needs it is probably worth all the effort.

2DIN car monitors, for the most part, are composed of a flat screen and a built-in DVD player. They also have an amplifier built right into the dashboard unit as well. You may discover that more unit mounts and connectors are required to get the car monitor to be seated in its slot snugly. Installation of this popular style of system needs a lot of re-wiring. If the outer edges of the monitor are too large or too small for a non-standard stereo slot then you may have to perform a custom resizing or remodelling of the dash to make sure the unit fits properly without any problems. A good rule of thumb is to double or even triple check the dimensions of your dashboard slot before even buying a brand new car monitor to install. This way you do not waste time or money.

In the process of your car monitor install you will most likely have to run wires from the head unit all the way to the individual Speakers in the front, side and rear of your vehicle. All other secondary input devices, such as backup cameras or Bluetooth kits, will also require this. A crucial thing you must account for is to make sure that you are not running a wire to both ends of the emergency break cable since it is considered to be illegal in most countries to be able to operate the monitor when the car is in motion. The only exception to this rule would be that you are running a rear view camera while reversing your car. A final note is that you will also need to wire the car monitor player to the power supply of your vehicle.

1 DIN Car Monitor System

This particular type of car monitor is very much akin to the 2 DIN since it is also mounted into a dashboard and is necessitates a great deal of wiring to have it installed correctly. Be that as it may, the 1DIN car monitor player only takes up ½ of the needed space of a 2DIN unit. Even though it sounds easier to attempt this type of car monitor installation you may need to customize the slot size in the dash to make sure it fits tightly into its designated spot. Similar to the 2 DIN car monitor system it is made up of a color TFT or LCD screen, DVD player and amplifier. All the connections, mounting brackets, and wiring are definitely required but may not always be included by the manufacturer in your purchase.

Alternative Design Car Monitors

This class of car monitors is much less difficult to install than the 1or 2 DIN monitors but it will still pose you with some unique issues. While it is true that you do not need to fit the new electrical Components to existing parts of the vehicle you are still required to perform a significant amount of wiring and rewiring to make sure the system is properly hooked up to an adequate power supply and stereo system to maximize your mobile multimedia experience. This type of car monitors installation you will require screws, wires, and adhesive.

For a headrest monitor install you will need to detach the fitted headrest from the seat and run power and connection wires down through the hole. The majority of cars or trucks should allow you to remove the cover off the bottom of the seat and put an unwound clothes hanger up through the slot to locate the cable and pull it out. After that you can run the wire under the carpet to the main head unit in the dashboard or directly to another connection box in another spot in your car.

Other unique car monitors, such as a sun visor DVD monitor or overhead car DVD monitor, will require you to consider other important factors such as how to fix the player to the ceiling of your car and how to wire the DVD monitor so that the cables cannot be seen by the passengers. When mounting the roof monitor you will need to install it in the center of the vehicle for maximum strength. Then you will need to conceal the wires beneath the ceiling panels by running them from the head unit to the dash or power supply. As you can see, this may require a lot of work as some panels and maybe even the seatbelt will have to be removed. Sun visor DVD monitors are not as hard to mount since the wires do not have to be extended too far to be attached to the power source or main adaptor. But they will still need some careful attention when removing and re-attaching car panels.

Clip-On Car Monitors

This one is the simplest and most flexible type of monitor to install when it comes to moving from place to place. They usually include headrest, sun visor and even arm rest car monitors. You should be able to plug a clip-on monitor into a cigarette lighter and clip them onto their designated location.

Now that you have a much better idea of the 4 types of car monitor installations you need to consider some important things.

The provided tips and tricks information is only a tiny portion of the things that you will need to know to aid you in an installation process. Installing a car DVD system is not something to be performed lightly, especially when you are attempting to install a 1 or 2 DIN car monitor or trying to perform a complicated headrest monitor install.

If you are serious about accurately installing a DVD multimedia player, and have the correct resources to attempt it, it is of utmost importance that you work methodically and carefully to avoid any confusion or unnecessary delays.

Some things to consider are:

1. Researching the installation project: Read over and make sure you understand all the instructions for the Components you are going to install. A good idea is to go online and search to see if anybody has attempted any wiring plans for your particular vehicle make and model.

2. Prepare for the assignment before you begin: If you are trying to install a 1 or 2 DIN install you will need to ensure you have all the necessary tools, Accessories and wires. In addition, you will also need to give yourself a few days without any distractions to thoroughly complete the job.

3. Remove existing Components carefully and skilfully: It is important that you do not lose any crucial parts or damage your old stereo system unless you plan to keep the car monitor in your vehicle when you resell it later on. Laying out panels and parts in relation to their location on the car with all their screws on the panel will greatly reduce searching time in your installation process.

4. Keep your work neat and tidy: When wiring or rewiring make sure that the wires themselves are as tight as possible and prevent them from coiling up.

People who rush head first into a car monitor installation project will usually find themselves stuck in a time consuming project which frequently ends up with undesired and often unsafe results.

There is absolutely nothing worse than a vehicle with wires scattered all the way through it. A professional installer would always makes sure that wires were tidied away somewhere behind the paneling of the car in nice neat straight lines. By carefully preparing and taking the time to properly do a car monitor install you can achieve similar results. Also, it is important to be aware of audio and visual problems that could come up from hastily assembled systems. Problems that may arise can include black holes in sound, flickering screens, or loose rattling components just to name a few.

If you don`t take the time to perform a car monitor install correctly it can be a safety hazard to the system, the car and ultimately yourself. If 2 wires are exposed they can short circuit each other and cause your new in-car DVD player to be inoperable. Wires that have been placed too closely together, in a faulty car monitor installation, for too long of a time period will fuse generating a temperature so hot it can combust causing a car fire. So play it safe and follow these helpful tips and strategies in attempting a proper car or headrest monitor install.
