Car Audio Amplifier Basic Install Guide By Brandon Noe

The longer you're into car audio the more chances you will have to install the components yourself. In this basic guide, I'll tell you certain tools and components you will need to install a car audio amplifier.

Amplifiers can be a little bit tricky to install. They require removal of internal panels and also the running of wires from the front of the car to the rear or wherever the car audio amplifier will be mounted.

After purchasing you car audio amplifier you will need to purchase an amp wiring kit. These kits usually contain:

* A power wire (big red wire)
* Inline fuse holder
* set of RCA's
* a long thin wire (mostly in blue color) called a remote
* some speaker wire and various wire connectors and wire loom

These kits also come in various sizes or gauges, with the most common being 8 gauge and 4 gauge kits. The smaller the number means the bigger the wire. 4 gauge kits will be plenty to handle up to roughly 600-1200 watt amplifiers.

Once you have got the car audio amplifier and amp wiring kit now its time to take a look under your hood and locate your battery. Once you have located the battery it's best to unhook the battery during installation so that you don't short anything out while working. Look around the firewall area on the side where your battery is located and check for any type of hole that would lead into the inside of your vehicle where you could run your power wire through. If you cannot find an easily accessible hole then you may have to drill one yourself. If you do have to drill one yourself it's best to make a small hole at first so that you don't damage any wires in the area. Gradually make the hole bigger with some type of step bit. Once the hole is made use rubber grommets to make sure the hole is sealed and that the metal edges don't cut your power wire.

Now that the power wire is routed though the firewall it's time to start to remove the internal panels for wire installation throughout your vehicle. During this process you will run 3 wires to the location of the car amplifier. Generally the amp will be in the trunk/hatch area. The first wire will be a red wire (which is the power wire you ran from the battery of the vehicle). The next will be a set of RCA's, and the final wire will be the thin blue wire we call a remote. In some kits the remote wire can be built into the RCA's. The RCA's are what sends the sound or signal to the amplifier and then is amplified through the speakers. One rule I generally use when running the wires is to separate the power and RCA's by running the power wire down one side and the RCA's down the other. If not done correctly there is a chance that you could generate some engine noise from within your speakers. The RCA's will plug into the output on the back of the radio, some CD players there will be a 'subwoofer out' set of RCA jacks that will give you more control over sound quality. The next is the remote wire (usually the blue thin wire) this is the wire that sends the amplifier the signal to power on when the radio is powered on. This wire hooks into the remote wire on the back of the CD player. Don't worry about the wires being too long during this phase of the process, they can easily be trimmed once you find were you want the amplifier to sit.

Once you have the wires run you can set your box and amplifier were it will eventually be permanently installed to give yourself a reference on how much wire will need to be trimmed. You will also be able to establish where your ground will go at this time; generally a body ground somewhere within one foot of your amplifier will be sufficient. Once you have located a suitable place use a little sandpaper to clear the area of any paint so you will have a solid connection to the vehicle body. Now you can connect all the wires to the amplifier and subs and hide any excess wire to make your install look more professional.

The final phase is to connect the power wire to your battery and install the inline fuse protector. With everything completed time to turn your system on and make all your adjustments to the levels you see fit for the type of sound quality that you desire.

Do Your Car DVD Players Have Illegal Software Installed? By Rose Li

Anybody who sells China car DVD players online, either through eBay or one of the eBay alternatives, or through their own online store knows what a cash cow it is.

But could there be a problem with the GPS car DVD players that they are selling?

There aren't many electronics that don't come from China these days and China-branded electronics always come at a cheaper price than comparable brand name products.

Essentially, if you buy something like a brand name automotive DVD player then there's a good chance half of the price that you're shelling out is for the name itself.

Take, for example a 2DIN car DVD with touchscreen. A brand name unit will set you back approximately 600 dollars US while something similar from a China brand supplier won't even cost you 240 US dollars.

Both come with the same warranties and features. The only difference is the name.

That's some price on a name.

It's unfortunate then that GPS car DVD players come bundled with a really big problem which will leave your customers stranded and customs officials asking you some fairly big questions.

Some of the car DVD players with GPS from China are sold with cracked or sample software.

What is worse is that some of the more unscrupulous online suppliers are a little reluctant to tell their customers that when it comes to GPS software they aren't getting the real thing.

This is a massive problem for anybody who buys these car DVDs as they can often be left stranded by software because they are unable to download updates or find themselves without it when they need it most.

It is bad for your business to sell illegal software.

You to can feel the ill effects of inadvertently selling products with cracked software.

Not only are you going to have to deal with angry customers who are left in the lurch because they can't update their GPS software you will have to deal with a whole lot of bad PR. You might even find yourself facing a lawsuit to boot.

So how do you find out if your supplier is sending you car DVD players with cracked GPS software?

Essentially you should only buy GPS-ready car DVD players from a supplier who offers a 12 month warranty and Quality Control check to protect you and your customers from cracked software.

However if you think you, or your customer has gotten a car DVD with cracked GPS software, just email software's serial number to the software provider's customer service department to make sure that you have indeed got the real thing.

Remember, your supplier's reputation and customer service is crucial to your reputation and customer service so don't be afraid to make sure that you are really getting the GPS software you are promised.

Your customers will thank you for it.

First Things You Will Need to Know About Car Audio By Brandon Noe

The first stop on the road to a louder car stereo system is to find the right head unit, otherwise known as a Head unit or CD Player. Some players are nothing more than a dash mounted single disc stereo with an FM tuner. Others are more elaborate with a dash mounted control head, Built in DVD players, Touch screen panels and a ten disc changer mounted in the trunk. Any of these can be bought at your local department stores, audio stores or an online audio outlet website.

- Next, you'll need some speakers to go along with the CD player. A set of four speakers, is the best way to go with two speakers to the front of the car and two in the back deck. Generally speaking, the speakers in the back of the car are larger than those to the front, and easier to install. Could also consider using Tweeters for a more high pitch clarity. There are many types of speakers you can run with in the front and rear of your vehicle myself i use a component set in the front of my car and basic 6 1/4 2 ways in the rear of my car, but each person have different sound tastes as i like to say.

- After you have your system installed, you'll probably decide it still isn't loud enough. That's where a good amplifier comes in. The amp takes the audio signal from the CD player and boosts the signal going to the speakers. When you're shopping for an amp, make sure the speakers you bought can handle the wattage rating of the amplifier. You'll want to mount your amp somewhere out of the way to keep it from getting damaged. The trunk is usually a good place, or under the seat also if you have the extra money to spend you can also go a little crazy and have custom Amp and speaker enclosures made with various types of wood, metals, and fiberglass with neon's or anything else you can think up to put in there. Another thing to think about but you'll have to have long enough audio cables to reach back to the head and heavy duty speaker wire to reach back to the speakers.

- While you're at it, why not install sub woofers as well. They will reproduce the bass sounds from your stereo with much more clarity, and volume, than the four speakers in the car combined. Now that you have all of this audio equipment installed, you need to keep thieves from uninstalling it. Car alarm systems are affordable and can be purchased at the same store you bought your CD player. They are relatively easy to install and well worth the money for what you have invested in your audio equipment.

All of this equipment is made by various manufacturers such as Sony, Kenwood, JVC, Panasonic, Pioneer, Alpine, Earthquake, Fusion, and Bose. Before you spend any money on audio equipment, you may want to do some research to find out what system is best for you. Ask some friends, read online product reviews or find a car audio forum on the internet and get some opinions there. That way you'll be sure to get the sound system you want and feel assured you got the most for you money..
