Troubleshooting Tips for Car Amplifiers

Writen by Chimezirim Chinecherem Odimba

Ever wished you didn’t have to take your car amp in for repairs every time a fault occurs? You wish you knew just what to do? Viola! Here are a few troubleshooting tips that can help you…

What to do when your amp goes into protect…
The amp goes into protect whenever the volume is turned up most likely because the measure of resistance to vibration is too low. Another reason may be that the charging system is poor. A transistor problem may also cause an amp to go into protect.

To check out these faults, switch off the power supply to the amp. Using a multimeter that has been set to ohms, measure the resistance between the output transistor terminals. If there is any one that reads -0 ohms between any of the terminals, it needs to be removed from the circuit and checked. Once a transistor has failed it means that the whole group in the circuit is shorted and needs to be changed.

Also check the wiring of the speaker to see the resistance to vibration.

What to do when amp gets very hot/shuts down…
This problem occurs when the input sensitivity(or gain) is set too high. If the impedance (resistance to vibration) is lower than the amp is rated for, it can also cause this problem or even permanent damage. The solution to this is to ensure that the gain is not tuned all the way up. Be sure to leave a bit of dial space between the maximum and where it is set. Also ensure that the speakers are connected to an impedance (resistance to vibration) that fits the amp.

What to do when your car amp does not turn on…
This is a situation that often occurs when amps are set up. This could happen for the following reasons:-

A. The surface where the amp is set on.

B. The hook up of the remote wire.

First ensure that the amp is secured on a smooth metal that is clean and rust-free. The amp must also be snuggly fitted. Next, check and ensure that the remote wire is connected to the blue wire with the white stripe that is hooked up to the head unit and not the solid blue wire.

If the problem persists, it most likely would be that there are parts that are blown or shorted. I advised that you take it in to be tested to ascertain the problem.

What to do when your amp Volume goes down…
Most new amps have protective devices that would keep the volume down when the amp begins to get very hot. If this occurs it means that the impedance and gain (input sensitivity) are not commensurate. Ensure that the gain is set correctly. (Refer to “What to do when amp gets very hot/shuts down”).

What to when your alternator whines or there is noise through the speakers…

This is usually because the amp is not set on a smooth, clean and rust-free surface and that it is not snuggly fitted. If you check these and the noise persists you may need to get a noise suppressor.

If all or any of these doesn’t work in your case, let an expert take a look at it.

My Experiences with Auto Navigation Systems

Writen by Morgan Hamilton

I was intrigued when I heard about this new technology called auto navigation systems. They say that GPS and other similar systems are accurate and sophisticated. I can drive around an unfamiliar location and a computerized voice will guide me to my destination. I was a bit apprehensive and I wanted to confirm if this new technology is as good as its hype. I got the chance to found out during a recent vacation, when I got the opportunity to use a rental car equipped with one of the new auto navigation systems.

I traveled to Florida where it can be tough to find your way around, especially in crowded tourist cities like Orlando. We were accommodated on a hotel on Disney property so my husband could attend a conference. As a result, I had a few days to spend exploring the area. Since I was alone, I didn’t want to get lost, so I thought that it would be an opportunity to check out the auto navigation systems.

I chose to rent an Explorer equipped with a GPS unit installed in the dash, and I immediately began to test it. I wanted to find out if it could lead me back to my hotel and to other nearby destinations that I already had the directions for. It did a pretty decent job, though it got a little confused when I ignored a turn command on a one-way street and it had to work out an alternative route.

That’s the thing with auto navigation systemsas hard as they try to advertise them as an excellent human guide, they are not human. They are flawed in the manner that all machines are, and they are unable to provide you with hints based on immediate information.

Auto navigation systems are incapable of reminding you to pay attention to where you’re going, to check the street signs, or make a quick turn. They can merely serve as guides to the limit of their programmed capacity and you need to do the rest. They are accurate for most of the time, but they won’t always give you the best way to arrive at a destination or provide you with updated information about detours and other possible changes along the way.

Hopefully, the technology in auto navigation systems will continue to improve, and future models may be able to sense that you’re about to commit a mistake and will aid you in avoiding it. Until then, it makes sense to be safe by obtaining directions from real people who are familiar with the area.

Mobile Phones Have Become An Integral Part Of Our Lives

Writen by Jennifer Lopaz

There has been a considerable increase in the use of mobile communication over the past few years. This development is expected to carry on in the near future with the new and different technologies being introduced every day.

Mobile phones have become a vital element of out lives these days. Nowadays, virtually everyone carries a mobile phone, including the young children. We can not even think of living without mobile phones. Mobile technology has altered our lives. It has evolved immensely since its inception days and now provides us with diverse ways of communication along with entertainment. With the latest java games, wallpapers, polyphonic ring tones, Bluetooth mobile technology, picture messaging, you can never feel bored.

Now one can see television programs on mobile phones any time, anywhere. We can also transmit emails, SMS, make plans for meeting, and take snaps all with the help of our mobile phones. In conjunction with the advancement of mobile technologies has come the development of mobile contents.

Mobile phones have evolved as an all rounded tools that provide us an easy, uninterrupted access to information, entertainment, communication etc. and that too when, where and how we want it, no matter what the device, service, network of location is.

Mobiles can today be used for not only making phone calls, but also for taking and sharing photos and video, playing music, and sending text messages. Today, mobile phone is a telecommunication and multimedia device.
