Amp can do wonders?

[Toonstar]

hi AutoS,

thanks for the reply.

Wat abt the tweeters?

 

also, what brands do u recommend for amps and speakers?

[Wintersonata]

Hi AutoS,

 

If that's a good brand then I might want to redo my entire car setup. Thinking of using their MP3 HU and their component speakers (Front & Back). Not sure whether i would need Amp also??? Maybe start with some basic setup first then.... My budget would be about $1k...

 

Well, really would need your expert opinion on this brand before I make-up my mind ....

Tweets almost always come W/ the speakers.

 

I am anti-brand conscious, pro-performance for money conscious.

 

Why not U call me 9787-0213 and we talk abt best options within Ur budget range.

[AutoS]

Bro,

 

Forget brand and brand . Give me a call 9787-0213, we should discuss what U already have which can be incorporated and what U wanna get short and long-term. Then we can talk how to allocate Ur budget to which hardware to get best desired results.

[Toonstar]

after reading those posting abt u..i dun think i wanna call already. Wow..u are getting notorious on the web with so many postings in delphi and over here!!

[Cool]

Toonstar,

 

On the contrary, let it be a test for yourself.

Give a call and you can judge for yourself.

 

I too get flame by people with sore-eyes. You only hear what others wants you to listen to their agenda. As you know, people flame me cos they can't get secrets out from me. I got people from other forums approaching close friends of mine to sell me out on my secrets without even offering to pay them a "token"... ridiculous isn't it. But, this is all about the selfish world of internet forums.

 

At the end of the day, the question is do you need to be a "brainwash" victim from both sides ? Take control of your decisions and shape your thoughts.

 

For me, I will call AutoS and take up my personal challenged. I rather use this "opportunity" to test my judgement via a phone call. Maybe you become a more better person after going thru this quest, and gain something from Human Relations and know better to handle different type of people in your working career. It is always people who make others successful and nothing else. You can get a pay rise if your boss don't back you out on it. At the end of the day, is how you manage human relations i.e people.

 

On the other hand, if you gets stories singing praises of AutoS, you will be brainwash to think it is a sales conspiracy.. so whether good or bad stories, both have hidden agenda.

 

We are all adults and professionals. If a simple forum comments affects your decisions drastically, I cannot imagine how the real world will affect your life, judgement, lifestyle and happiness.

 

Life is short, you don't need enemies or have unpleasents thoughts carried with you everyday.

 

cheers.

 

P.S> I have not relations with AutoS or have my car done by him before.

Understanding Car Audio Systems: The Amplifier

By Scott Memmer

Last updated: 2002-03-19

 

Before we go any further, let's define our terms here. When we say "power amplifier" we are not referring to the entire amplification stage, but specifically to power amplification. You may recall that in Parts One and Two we touched upon the amplification process as a whole and broke it into two separate component groups: the power amplifier stage and the preamplifier stage.

 

Although both of these processes reflect opposite sides of the same coin, they actually work quite differently. The preamplifier serves more of a routing and control function, while the power amplifier deals with delivering brute force to the speakers.

 

Since its functions diverge from our discussion here, let's dispense with the preamplifier stage for now. We'll return to it in Part Five to take a final look at the preamplifier and discuss how its features aid and enhance the in-car entertainment experience.

[Tantt70]

So...the power amplifier. What does it do? How does it work?

 

The power amplifier's main job is to deliver a boosted, or "amplified," signal to the loudspeakers. The technology for this actually goes back more than a hundred years, to Thomas Edison and the light bulb, but it took a quantum leap in the '50s, when Sony introduced the transistor for commercial use, to pave the way for the power amp as we know it today.

 

Prior to this, most electronic devices

[Tantt70]

Earlier in this series we mentioned that heat is the enemy of most electric components, specifically amplifiers, which generate a lot of heat during operation. Therefore, except for small, lower-powered systems (10 to 20 watts per channel), which have the amplifier attached to the rear of the radio, most car audio amps will be located remotely from the faceplate, connected by a cable.

 

Since amplification is the last stop for the audio signal before it goes to the speakers, the amp merely takes whatever signal is delivered to it (after tone adjustments, balance/fade, etc., have altered it) and increases it. But that "merely" makes all the difference in the world, and it's the reason people will pay thousands of dollars for an aftermarket system that delivers awesome bass.

 

Before we define some amplification terms, a little more on heat. As stated above, larger amps (those above 10-20 watts per channel) are located remotely from the radio. This is not only because larger amps take up more room. A high-powered amp needs to "breathe" much as the cooling system for your engine breathes. Looking at the pictures of Pioneer and Kenwood amps we've included here, you'll note that they have "ridges" and "valleys" on top. Similar to your car's radiator, this design increases the surface area of the amp, allowing the metal to "radiate" the heat generated inside the amplifier back into the environment.

 

Through a series of transistors, conductors, rectifiers, resistors, inductors, capacitors and circuit boards, the inaudible signal coming from your radio passes through the amplifier and is "boosted" into the audible range. Once this is accomplished, the signal is delivered to the speaker terminals at the other end of the amp. Speaker wires connected to the terminals then carry the amplified signal to the speakers.

 

Amplifier output is typically measured in watts per channel, with a normal stereo system having two channels, left and right. You'll frequently see "RMS" after the wattage figure

[Tantt70]

Third is the "peak power" rating. This is a snapshot of the amp in one particular moment of performance. Any decent audio amplifier will produce two, three, even four times its RMS power for a split second. However, to use this as its actual power rating would be like saying an Olympic weightlifter who cleaned and jerked 500 pounds had the "carrying capacity" of a quarter ton. Not exactly truth in advertising.

 

If you see "maximum power rating," or "total system power" or "peak power rating" on a box or a brochure with no other RMS figures to justify it, head for the hills. Either that, or divide the number in half for a more realistic RMS rating.

 

We once had a friend in the car audio business who called these numbers the "ILS" ratings

[Tantt70]

Therefore

[Tantt70]

One other term you may have heard in connection with amplifiers is the "crossover." What is a crossover?

 

Simply stated, a crossover is a device, sometimes built into an amplifier, which divides and directs frequencies to different loudspeakers. For instance, many car audio systems we review on our Web site have a two-way speaker system built into the front doors of the vehicle

[Toonstar]

thanks..but i rather stay out of all these forums grunches and stuff like dat.

[Cool]

Good.. I support you.

BTW... Simlim Towers do sell go speakers and Amp, got mine from there for the AMPS.

[AutoS]

Well Toonstar I couldn't blame U for feeling this way. The latest round in the ICE forum is really bad. The individual here making claims and flames has his own hidden agenda. Wouldn't be surprised if U get prospected soon.

 

Thing is it started off W/ that one guy who got his wire in the door damaged when speaker was mounted cuz the spkr screw pierced it. True it is our responsibility even tho it was an accident that has never happened B4 and in a way quite unforseeable. To fix the problem was a simple matter of replacing and reconnecting the wire. I wasn't given the chance to do so and I did pay for it when it was sent to the agent to do without my knowledge.

 

Next the customer wants to re-harness the whole car which I did not want to do since the fault is done and paid for. Guess I could have avoided this whole public affair if I had just paid up the the $600+ but somehow I just felt like I was being blackmailed and didn't want to succumb to it. After all it was just a mere wire disconnection nothing else was faulty.

 

The other Guy W/ the Swift had done his job almost 2yrs ago. The 6" speaker mounting on that door was not a simple affair as their is no original mounting catered for and the door panel is undulating and contoured. The install was solid and he accepted it happily at the time. As I mentioned to him if his speakers had worked loose after all this time and some interference has come into the system, the logical thing to do is to just seek me out instead of airing it on a public forum. I will rectify gladly even after all this time of wear and tear. He has since relented and stated that he is happy to accept the offer that was always there as after sales service in the first place anyway.

 

The other 2 Guys were extremely difficult customers. One who was particular about his sound performance but was not prepared to work with me even for the shortest time to get exactly what he wants after initial completion. Worst still his own small damages to his car was not of our doing, a few very minor surface scratches on his dash were there from a previous install when the car came to us and the small dent in his front bumper was not there when he took the car. After using the car and then decided on Sunday wash detected the ding and thinks we are responsible wanting to claim a new bumper. The ding is most likely caused by another car backing into it and can be massaged out. Whilst his car was with us I made sure his car was parked in such a way that absolutely no other car could have possibly come close. I am not one to shirk away responsibilities to customers car. This is something we got to be prepared 4 becuz no matter how careful once in a while ... it's all intensive handwork.

 

The second Guy W/ the SUV suffered a crease in the back cardboard panel covering the floor board and a surface scratch to the lower console at leg level which can be polished off. Yes we were working late, this is the fault of my worker and no excuses. sxxt happens and I try to avoid it as much as possible. The Guy proceeded to check his whole car W/ our portable fluorescent light. For that the Guy shorted me ard $1.5K on the bill which got no argument from me, since it was our fault but yet he's on the forum when the sxxt hits.

 

These are the 3 Guys that I can remember clearly recall where we have had this kinda problem W/ over the last year and a half or so. Best part is honestly racking my brain I cannot recall any others. I certainly hope there are no others that come out of the closet that I don't know about. This grand total of 3 are users of the ICE Forum and obviously monitor the forum and as such not surprising log in complaints at this opportune time. Best part even others, some individuals using multiple nicks, with hidden agendas, like some unidentified but in the biz join the fray. Of course so many condeming one me, I really cannot blame U or anyone else for having doubts.

 

What I can say is that there are tons of ICE Forum members, I paractically do 3 a week on average, so many who have done and gone away very-very happy and many have stated so in the forums in the past. Even members from this forum have had dealings W/ us and have been happy W/ results and posted so. Such a mess and it really is a mess this time, I am not surprised that individuals from this large majority would just stay on the sidelines, but it is these individuals that are more indicative of the overall expertise, quality of work and service.

 

My company has a solid rep for the best car audio installs in Sgp based on the actual installs done out there. Even those who oppose cannot make any substantiated negative claims cuz all those installs we have done speak for themselves. That's why I always invite pple interested in ICE to come and audition any of our available installs even tho they may not be immediate potential customers. As a true enthusiast I am always keen to show pple my interpretation of what car audio should sound like. If it promotes biz fine. If not that's OK too.

 

The moderators here have told me even B4 this mess that there are commercial interests here so have requested me not to 'market' myself. I respect their decn and reasons for it and this here is not a marketing effort. But it is an effort to substantiate all this really bad publicity not only on biz but personal rep from where I stand.

 

As for U by all means seek out another installer and have peace of mind.

 

As in the ICE Forum I will not react to any posts of a personal nature no matter how defamotary, cuz then it just invites an escallation which is just bad for the forum as a whole. But if Bros have any genuine ICE issues I am still Ur Man. Altho my directness has won me too many enemies it's good for U Guys if U need direct honest ICE answers to compare and verify. Info I give out freely I can say without a doubt will get pple a lot better audio performance and save pple a lot of $$ pitfalls. This is my forte built up over several years of concerted effort and interest.

 

Cheers and a Good New Year ahead to all!

hi..i know both the sim lim sells stuff cheap..but the prob is i dunno which brand to buy nor is familiar with the specifications that will be good for my car.

[Toonstar]

cheers. fyi..i was warned by that first posting of you. Way before that, i was warned already.

[AutoS]

Well Bro,

 

All I can say is there are others who have done their sound systems W/ us right here in this forum and are very pleased W/ results. I can tell U that I get into car audio in a much more profound way than others in the trade and apply it to installs for better results whether it be simple or complex systems. Our customers systems have been seen and auditioned by many and speak for themselves. BTW there are some of our regular customers, when they were first in contact W/ me on the ICE Forum actually got private mails warning them of all kinds of things about me. After doing their systems and getting to know one another better they informed me of this.

 

U asked me for opinions, I givee U only honest and correct answers. No I am not trying to convince U, just making a point. Indeed taking into consideration what U have been warned, considering appointing us to do Ur car system...should be no consideration. On my end I would never want to do a system in a car where the owner had any mistrust of me. However if U do need some helpful suggestions I am more than happy to oblige here.

 

In the meantime best of luck W/ Ur audio upgrade.
