All about Equalizers

With all the power an variables that you can get from your system, being able to fine tune is gold. Sometimes, the difference between a good and great system, is the equalizer. Many receivers come built-in with an equalizer, but most of these give you very limited controls. Just by adding an external equalizer, you will be able to make fine adjustments. Remember to make very light adjustments though, as the signal will be amplified many times as it goes through the amplifier.

Even with a good setup, the result of sound bouncing off various surfaces in your vehicle can produce an undesirable result. This is when equalizers proof its worth giving you the ability to tweak the signals to your hearts content. EQ’s can also help protect quipment by limiting frequencies that your speaker drivers can’t handle.

Here are a couple of things to lookout for when picking an equalizer

Inputs and outputs

Be sure the number of inputs and outputs suit your needs

Fader

Some EQ’s provide fader adjustments even though your receiver has only one pair of outputs. Fader controls are really useful in fine tuning the rear fill

Subwoofer Outputs

These work like crossovers, allowing only certain frequencies to be sent to the subwoofer.

Number of Band adjustments

The more bands means finer tuning

Choosing a Subwoofer

Adding a subwoofer to your system is a right step into getting a more complete sound. So, how do you decide on which subwoofer is the right one for you. There are basically 3 groups that you may belong to.

1. I want to keep my trunk space and don’t want to fuss about with amps.

If space constraint is an issue for you or perhaps your vehicle, then a powered compact sub may be just what you need. These space-saving subs are ideal as it has a built in amplifier and you can place this sub under the seat. Bare in mind though that if your goal is to blast your audio to kingdom come, then this may not be enough as it is limited by space. Don’t get me wrong though, these subs do add a significant difference in getting the lower frequencies in your system. Life is always better with a subwoofer, trust me.

2. I have trunk space, but don’t want the trouble of having to add an amp.

If you have a little bit more space, say your trunk to give up, but don’t like the idea of having additional amp, then a powered enclosed sub is ideal as it is able to provide more as it is less constrained by space compared to the compact powered subs.

Enclosed Powered Subwoofer

3. I want subs to be perfect to my taste

All you need to do then is to match the right sub to the amp and get an enclosure that will suit it. Voila!

So, now that you know which group you belong to, the next thing is to consider some of the details when picking out the sub for your system.

Size

What size subwoofers should you get? I’d suggest go for the biggest your space and budget will allow. Remember to take into account enclosure size.

Power

The more power, the louder you can go. Be sure to match your sub to your amps power-handling rating. Always look at the RMS power.

Sensitivity

The higher the sensitivity, the less power it needs to be loud. This is ideal for the average user with a low powered amp. If you wanna go loud, go for a lower sensitivity subwoofer and a high powered amp.

Frequency Range

This will let you know the range that the sub can achieve.

Impedance

This is important when matching the subwoofer to the amplifier

Voice-coils

Dual voice coils allow for greater flexibility in the wiring setup

Enclosure Type

Generally, there are 2 types. Ported and sealed. If you plan on going loud, then a ported enclosure will allow pressure to escape which means you can push your subwoofer harder. A sealed enclosure can’t be pushed as far, but it provides a deeper and more accurate low frequency reproduction. Ideal if you’re after sound quality.

Choosing Amplifiers for your system

Amplifiers can provide a fuller more dynamic sound even at low levels

Amplifiers can provide a fuller more dynamic sound even at low levels

Amplifiers can be added to all systems be it audio or aftermarket. It’s all about matching the right amplifiers to the speakers. Amplifiers generally allow for better sound reproduction as it isn’t bound by the space limitations of the head unit. Therefore better design and materials can be used to produce superior results.

Generally, amplifiers can be identified by the number of channels. Mono, 2, 4, 5 and even 6 channel amps can be gotten.

The monoblock amplifier is typically made to power sub woofers. It is made for low-frequency reproduction and is ideal to power a subwoofer. 2,4,5 & 6 channel amps can be used to power full-range and component speakers. They can also be bridged to power a sub or two.

Generally, the rule of thumb is to get an amp that is 75% to 150% the power-handling of the speakers. Again, always look at the RMS values and not the peak power values. The number of channels will depend on the speaker setup and if you are willing to get 2, 3 or more amps.

Choosing the right Speakers for your System

Speaker Size

Choosing the right speaker isn’t as hard as you think. The first thing you may want to consider is how much fuss is acceptable to you in terms of installation. If you prefer it not to be a fuss, then I’d suggest to go with speaker sizes that will replace the current speaker location you have. This however can be limiting depending on the current setup on your vehicle and also the goal you are trying to achieve. If you are after big and loud sound, then I’m thinking you may need larger speakers that may not necessary fit snugly in the factory hole. In cases like this, you will need some custom work done to be able to fit the speakers. if you are going only slightly larger, then there are speaker adapters and brackets available in the market.

Speaker Adapters

Speaker Adapters

A few parameters when it comes to speaker sizes are Diameter (if its round), width x height (for oval shaped) and also depth measured from the end of the magnet to the top. Typically speakers come in a few standard sizes but depth will vary depending on magnet size.

Round Speakers

Round Speakers - Measured in diameters (4", 5", 6" and so on)

Oval type - 6" x 9"

Oval type - 6" x 9"

Speaker Type

Speaker types can be broken into two categories. Full-range speakers and component speakers.

Full-range speakers usually consist of a woofer and tweeter mounted on top of the woofer. These make the most sense in terms of straight forward speaker replacement with minimal fuss.

Full Range 2-way speakers

Full Range 2-way speakers

Component speakers consist of a woofer, tweeter and external crossover. The tweeters come separate which allows it to be mounted at a separate location from the woofer providing better imaging. The external crossovers allow for a better design and also improves the way the signals are separated and sent to the individual drivers.

Sensitivity and Power-handling

Besides size, the other thing that needs attention when choosing the right speakers for your system is the sensitivity (measured in dB) and power-handling (measured in Watts).

Sensitivity is basically how much sound the speaker will produce when power is supplied. Low powered head units with no amplifiers will work great with high sensitivity speakers. Low sensitivity speakers will suit high powered systems better, such as having an amplifier. Speakers when coupled with the right amps can produce great results!

Power-handling is the amount of power the speakers can handle. A low powered system can be paired with a low power-handling speakers and high-powered systems can be paired with high power-handling speakers. it’s best to match the speakers to the amps for best results. Another important thing is to always look at the RMS power and not the peak power.

Materials

It’s usually obvious just by looking to know if the speakers are made well with good materials. There are numerous materials used to make speakers that trying to know what sounds the speaker will produce is just plain impossible. Instead, I always advice judging it by eye. If it looks like it uses cheap materials and poorly constructed, then it probably is.

Generally, the typical materials that I find works are Polypropylene woofers, silk tweeters and rubber surrounds. However, there are many variations of materials used out there so the best way sometimes are to give them a try and see if you like it.

Improving your vehicles In-Car-Entertainment System

Imagine this, you’re about to take a trip out of town and will be driving with a couple of your best buddies about to have the adventure of your life. You drive off, everyone’s getting comfy and just as you are about turn up Bieber fever on your stereo, you hear a nasty snap, crackle and pop from your system. Bummer. More often than not, most of us are aware of the sub-par audio system  in our vehicles (Unless you are Mr. Rich and drive an expensive car, which if it is the case, then stop reading, this article ain’t for you Richie Rich!) and want to do something about it.

However, trying to figure out the right upgrade can be a little overwhelming given the choices of brands and specifications out there. Figuring out the right components that need replacing is equally troublesome, not taking into the account the sales hype and obnoxious sales talk.

Here are some components you can consider if you are looking to improve your system, in no particular order. Don’t live with a bad system. The amount of time spent in your car, especially in traffic, why not make it that much more enjoyable. It doesn’t have to be expensive either. The smallest changes can sometimes give reasonably better results.

This write-up is targeted to the average user and not advanced enthusiasts, therefore it will be kept simple and not go too in-depth on the technical aspects.

SPEAKERS

Pioneer Component SpeakersThe most basic, bang for the buck upgrade that you can do. If your vehicle is still using the speakers that it came with from the factory, then pretty much any aftermarket speakers will improve the overall sound. You’ll be surprised how much difference it can make.

Factory speakers quite often use sub-par materials and have very basic designs, hence the limitation in it delivering quality sound. A simple swap for a 2-way or 3-way speakers will give you better high’s and low’s and you will notice a greater variance in sound. If you are looking for a more advanced setup, then component speakers with crossovers are a must.

Choosing the right speakers for your system

 

HEAD UNITS / RECEIVERS

There are a wide range of receivers in the market. Depending on your needs and budget, there IS a right unit for you out there. From basic Digital Media Receivers with USB slot to Double-din touchscreens. Some head units come with better sound processors and DAC (Digital to Analog Convertors) that gives superior sound quality when compared to factory receivers. One thing to remember here is that if you play digital files often, to use lower compression.

Choosing the right Head Unit

 

 

SOUND DAMPENING

Silent Sound Dampening MaterialSound dampening will help in 2 ways. Reducing the vibrations and rattles from your panels while improving the ability to maintain the sound accuracy from your speakers. The other benefit of using sound dampening materials is that it will help in reducing interior noise and ambient noise. When this happens, you are able to enjoy more of the actual sounds without it being polluted by external noises, especially during higher speeds.

 

 

AMPLIFIERS

AmplifierAmplifiers are essential if you are looking for a complete system. Even high-end cars come equipped with it. Why not in your family sedan you ask? Simple. Cost. the same reason manufacturers put inferior speakers with paper cones in your car. Amplifiers can provide cleaner power than your head unit and improve sound reproduction plus also give you the ability to use bigger and better speakers.

SUBWOOFERS

Slim SubwooferSubwoofers are crucial if you want a full sound. No if’s and what’s about it. Without a sub, you can never get the proper lows. Especially for vehicles with touchscreen monitors and DVD playing capabilities. If you have ever watched a movie with and without a subwoofer, I’m pretty sure you get the picture.

Many people are turned off by subwoofers due to it taking extra space and also it’s booming sounds. Fret not, these days, there are powered subs that eliminate the need for an amp and also slim enough to fit under the seat. Furthermore, you do not need to set your subwoofers to maximum if club thumping sounds ain’t your thang.

Choosing your subwoofer

EQUALIZERS

VSL EqualizerWhat’s power without control? This is quite literally the truth when it comes to your audio system. With good speakers, amps and receivers, you need a way to control all that and the basic controls in most receivers are simply not enough.

PRE AMP

VSL Pre AmpPre amp is basically a component that amplifies and prepares the source signal before amplification. It helps in making sure the amplifiers are receiving a powerful enough input. Pre amps come either built-in to the source unit or an external unit. Some pre amps also serve as convertors, inputting high level signals to RCA outs which can then be plugged in to amplifiers which have no high level inputs.

 

 

 

HIGH QUALITY CABLES

RCA InterconnectBetter quality power leads and RCA cables to your amplifiers will help improve sound significantly. Having the right power cable that can handle the power needed by your amp is crucial. Not only that, a good cable with proper made terminals will ensure smooth flow of power and also ensure that noise caused by the cars electrical system is rejected.

Same applies to RCA cables. Cables made with superior design and materials that suits your application definitely help maintain the performance of your system.

Don’t let poor cables limit the potential of your setup
