In the last twenty years or so, with the invention of stereos with a high volume capacity and Mp3 players, one of the side effects or regular uses at a high volume is short term and long term hearing problems.

Although listening to music itself in the car at an ordinary level cannot damage your hearing, listening to very loud music in a confined space such as a car can have effects upon your hearing. Consequences start from temporary hearing loss to serious symptoms such as tinnitus, which leaves you with a constant ringing in the ear, despite the fact that there is no related sound. This is often caused by ear infections or noise related hearing loss. The ringing or whooshing in the ear experienced by tinnitus sufferers is a phantom sound and is often of a frequency, which the ear has lost due to noise related hearing loss.

Tinnitus is a very serious condition and can be permanent if an individual continues to expose themselves to those damaging conditions. Sadly for most, there is no way to cure it, only to deal with some of the symptoms. It is recommended that rather than treat it, you take precautionary methods, so that it does not occur.

Prolonged exposure to sound levels, around 70 db and upwards, can cause permanent damage to your hearing, so avoid listening to loud music on a regular basis. Make sure you take care of your ears by keeping them clean and using ear plugs or muffs around high levels of sound wherever possible.

With cities getting louder due to the sounds of traffic and workmen, it's not easy to avoid loud noises. Thus when in the quite of your own home or car, it's vital that you allow you hearing to rest from the loud noises of everyday life. So avoid loud music and sitting near loud speakers at concerts, gigs or clubs.

In your car audio system, keep the noise down to a good level. Make sure you have a good car stereo with an amp and subwoofer, which works well at average sound. Many music listeners, because of distortion in their car audio system, turn up the sound so they can hear the music over the distortion; however, this is obviously not the best idea for your hearing. Instead buying a system that is clear and without distortion will enable you to get clear music at low volumes. This can usually be achieved by buying a good car CD mp3 player, amplifier and subwoofer (which are used for increasing quality of output as well as volume).

Car Amplifiers: What Are They?

Is the sound quality on your car stereo at best, awful? But uncertain what to do about it? It's about time you invest in an amplifier for your stereo, but what are they exactly?

Most of us have little knowledge when it comes to electronics, hence, it can be very difficult for those of us who are not in on this ‘loop of knowledge' to know what to exactly purchase. Often going up to the sales assistant for advice is a task that at least makes one sweat, as the sales assistant tries to sell you extra products that you will probably not want or need.  Going into a shop with even a little knowledge is certainly better than going in naïve and unarmed.

Car stereos are these days not the simplest of electronics, as they have a number of gadgets that are designed to improve sound quality – one of these being the amplifier. This is a separate system from your stereo, which aims to amplify audio signals when the car's stereo's amplification is insufficient. It strengthens the audio signal when driving, so that the sound is at an appropriate level for car speakers when driving.

Amplifiers or amps, as they have been appropriately shortened to, are classified under the number of channels they have. A channel is one power or speaker output of an amplifier. Most people who want a reasonable signal and sound quality will go for either a two to four channel amp, whilst those with a specialist interest in car stereos will choose a amp with a bigger number of channels, as the more channels you have the more adds on and gadgets you can have.

When considering purchasing an amplifier it is highly important to ask questions about the amps efficiency and power. By efficiency, I mean how efficiently the amp consumes and distributes energy. For instance, an amp might consume 100 watts of power from the battery, and only distribute half of this to the speakers, whilst the rest is transformed into heat. In the amps specifications, it will tell you the minimum and maximum output of energy as well as the power output (in ohms).

Amplifiers are also classified into A, A/B,B and D. These divisions refer to the way the amp operates, for instance class A are inefficient power consumers but the sound output is generally better. These are, however, rarer than their counterparts. The most common amp is the A/B class – a highly efficient amp that provides excellent quality sound output. Whilst, a class D is the most efficient model, reaching up to 80% efficiency, and is often combined with highly inefficient subwoofers, so that the stereo and its additional equipment don't use too much battery power.

An amp is one part of a car audio system, however it is not necessary, unless you want subs and in turn, overall better sound quality.

Why is there 4 terminals per voice coil on my subwoofers?

ok well i have 2 of these subs
http://www.caraudiodiscount.com/aw1205-12-inch-2000-watts-subwoofer-p-13416.html

they are DVC, with a voice coil on each side but each one had 2 plus and 2 minus terminals...im not sure why,
(in all the wireing videos on DVC subs there are only 2 terminals per voice coil)
..shouldnt there only be 1 plus and 1 minus on each or is it right if so if i wired them up like the 2nd diagram on here...
http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=22
(to make a 2 ohm load)
... which of the 4 terminals on each voice coil would i wire them to?

ill be useing this amp

Think of it this way: the positive terminal has two connectors, and the negative terminal has two connectors. There aren't four terminals at each voice coil; there are two terminals, each with connectors for two wires. This is just for ease of wiring. For most sub wiring configurations, you might have one wire running to the box terminal, and another wire running to the other sub terminal. Having dual connectors just makes the wiring easier.
