Car Audio Equalizer: Do you need it?

Whenever you come across an audio system, you’re bound to bump into the word equalizer.

I’m sure many already know what it means, but I also believe many are either unsure or know very little about equalizers and if you should have one. And more importantly, what function does it serve and do you need it. To get started on this subject, I guess its best to start from the word ‘Equalizer’.

A quick search on Wikipedia brings up this:

  • Science and technology - Equalization, the process of adjusting the strength of certain frequencies within a signal.
  • Equalization (audio), frequency-dependent processing of audio signals.
  • An Equalizer (communications) used in telecommunications.
  • Equalizer (mathematics), the solution set of an equation.
  • A term sometimes used to describe a whippletree

‘Equalization (audio), frequency-dependent processing of audio signals’

This is what we are after. So, from that, we can gather that equalizer, in our context refers to hardware or software that carries out such functions.

Understanding Audio Equalization

Equalization is basically the process of adjusting the loudness of specific range of frequencies, and this can be done with software or hardware which we refer to as Equalizer or EQ for short.

Why would you want to do that?

The reason behind audio equalization is due to the nature of audio signals. Sound travels around by bouncing around surfaces, and this can sometimes be rather unpredictable. For example, if you were to shout in an open field, versus in a cave, it would sound different right? Same goes for speakers. When you put them in different locations and surroundings, the resulting sound will be different. So, with an equalizer, what an audio engineer could do, is adjust the loudness of a range of frequencies so that any spikes or dips in the audio signal can be compensated for.

Another reason behind equalization is also aesthetics. We all have different preferences when it comes to sound. What sounds good for one person, may not be for another.

Choosing an Equalizer

Firstly, you have to look if you already have one built in to your current receiver. Some basic one consist of just treble and bass. Some has an additional mid control. These are the more common ones available in basic car stereos. In more advanced models, you may find up to up to 30-band EQ’s. These allows for the user to fine tune the tones even further. I’d suggest you play around with the controls and see if you can achieve the sound to your liking. If you find the controls are insufficient, then you probably would need to consider an additional external EQ.

There is a vast array of EQ’s in the market and you have to decide what will suit you. Consider your audio setup (or what you would like it to be). EQ’s come in all shapes and sizes, but here are some common features you may want to look into.

1. Number of bands

2. Fader

3. Built-in Line Driver

4. Subwoofer output

5. EQ Preset Memory (Digital EQ’s)

6. Parametric/Graphic

There are also EQ’s or sound processors that come with a whole range of added features for advanced users. For example, Zapco has an entire series of amplifiers with built in sound processors.

Summary

So, do you need an EQ? Yes, if you do not have one at all. But if you do, I’d suggest you tinker about with your system and see if you are satisfied. If you are, then that’s it. Jobs done. But if you feel that some frequencies are too harsh, some to mild, and the existing controls just doesn’t cut it, then I’d say go ahead and get one. Don’t get one for just the sake of having one. We should all be smarter than that.

Death of the “Car Scene”

Is the “Car Scene” dead?

Looking around me these days, I can’t help but to ask myself, is the “car scene” dead? By “car scene”, I mean car modification, racing and car lovin’ in general. Everything to do with cars basically. Gone are the days of weekend races, loud exhaust mods, loud stereos, loud body kits and loud everything else.

“What do you mean the car scene is dead?” ,  asks a voice in my head.

Well, look around. Remember the days of the Proton “Wiralution” VR4, Honda Vtec EG, 4 Throttle Corolla, Perodua Kancil Turbo and the likes. No doubt a pitiful few are left roaming the streets, but the rest have been replaced by stock standard Gen2, Altis, Camry, Golf, Myvi, Vios and City. I hate to say this, but cars I see these days are…downright boring. Where has the imagination gone? Where has the individuality gone?

Volkswagen Old School GatheringEven the most recent, supposedly “biggest” car expo in KL which I went to, things seemed to be rather mild. Turnouts weren’t great, even the cars on display was dissapointing. Yes, yes, the big boys like Toyota, Honda and Perodua (no show from Proton) still showed up with a bang, but that’s about it my friends. These big name manufacturers will always be around as far as I’m concerned. Well, at least till they go broke. But where are the smaller guys? We used to see smaller aftermarket parts manufacturers out in droves during these events. Brands like Tein, HKS, Greddy, Blitz, Motul, Apexi, Defi and many more.

Throwing the question around the room, I get answers like, “Economy slow lar bro’, where can afford”. Then there are those who say cars these days are so good that you needn’t do anything to it anymore. I beg to differ on the latter, but first, let’s take a look at the so-called “reasons” why the scene is dead.

  • Poor economy – Which leads to less spending on cars (or car modifications to be accurate).
  • Cars are good enough out the factory.
  • Cars are less customizable these days.
  • Car prices has gone through the roof.
  • Shift of interest to digital lifestyle products.
  • The “cool” factor is lost.

Poor economy / Shift of interest to digital lifestyle products.

True to an extend I would say. The rise in prices of everything, be it due to inflation, currency exchange or other factors has probably had an impact on the ability of car enthusiasts to spend. However, I think that spending has somewhat shifted more towards digital lifestyle products such as smartphones, tablets, camera’s, portable music players and so on. Smartphone and tablets being the most obvious. Look at how a very well known online phone seller is now having a building by the Federal Highway. I bought my phone from these guys when they were just a couple of shops about a year back. They have a building now???

Another place I notice where spending has increased is in travel holidays. With the availability of cheap flight tickets, everyone is taking a holiday or two (some three and more) yearly. Now, back in the day, having an overseas vacation was a true luxury. These days it seems, it is a necessity. Facebook is further helping promote this. I think everyone has probably noticed some of  your “FB” friends posting holiday photos all the time. Some even during the holiday, because its soooo important that your friends get updates right? Go figure. So this increased social pressure causes others to feel inadequate unless they too update their holiday photo’s on Facebook.

Well, I’m all for travel and have been guilty of taking too many holidays myself. The only thing I would like to say to the many people who complain about the poor economy is “Cut down the freakin’ holiday trips!”. If you go on holiday, then quit bitchin’ about the economy for goodness sake.

Cars are good enough out the factory / Cars are less customizable these days.

Bullshit! Yeah, you heard me. I mean yes, cars have improved by leaps and bounds. They are faster, safer and more efficient. Nevertheless, car modification is about pushing the factory limits and a display individualism. Flames on cars never made the car any faster, but boy did it make the owner feel good. Pink fluffy interior never made the car safer nor more efficient. It is all about individual expression, making it your own.Pink Box

And if you’re going to tell me that cars are fast enough out of the factory, you are probably right. But it was never a question of fast enough. It was always a question of how much faster…

Cars are too expensive these days.

Agree. Here are a few tips to help you save.

  1. Do not opt for the fancy upgrade options. They charge you multiple times of what it is actually worth. They temp you with warranties and such. Do the math yourself and see if it makes sense.
  2. Consider getting a used car.  A new car is not necessarily better, safer nor less problematic. The opposite is also true. A used car is not necessarily worse, less safe nor more problematic. Distinguish between myths churned out by the manufacturer and common sense.
  3. Take cheaper holidays.  Cheap flights are really not cheap. If you never even flew once a year before and are flying 2 to 3 times a year now. Then it’s not really cheap is it?

The “cool” factor is lost.

I agree. This is somewhat bittersweet for me. You see, I’ve always loved the whole “car scene” even from back in the day. I remember flipping through magazines and salivating over super clean rides, chrome engine bays, 20″ rims, super loud stereos, lowered stance, turbo charged kits and the list goes on. I remember friday nights when we used to head down to Batu 3 Shah Alam circuit to enjoy drag races between Skyline’s and Satria’s, Corolla’s and Evo’s, Kancil’s and Subaru’s….all modified of course. I guess it was cool those days, but apparently no more. But I’m thankful. Just as in business, where it takes an economic downturn to weed out businesses that create no value. It’s just the same, but in this case, weeding out the fake enthusiasts. What remains are those who still pursue the love of cars and everything about it, even though its unpopular. It’s always good to be around genuine people.

Having said all that, I still do wish the scene was alive and kicking, that everyone around me could “talk car”, that car magazines made a comeback and car themed tv shows were aplenty. Perhaps I’m asking too much. Perhaps I’m a fool, a dreamer even. I am a car enthusiast after all and if there is one thing we have, its imagination and passion.

Adding New Lanes with Zippers

Check out this cool lane-zipper that creates an extra lane to ease traffic. We could definitely use one of these on our roads. However, no matter how many extra lanes we add, we just need one road hog on each lane to put all these efforts into vain.
