Car Forum / Driving, Maintenance, Tuning / Car Audio / January 2005Newbie Question - why an amp?
What's the benefit of having an amp hooked up to your car stereo. I'm not trolling. :) Please be gentle, John in NH ~~~ That's nice, but what does this have to do with Rush?

Does it simply make things louder? Clearer? And if it only makes the signal louder, why would I need an amp when I have a volume knob that does that.

No he cant be the dell guy, he's the computer support guy on Saturday Night Live! Damn this is funny, If the hassle of finishing words bugs you, how do you deal with say....... the microwave.

Not everyone is using CAF as a portal to rec.audio.car. Some of us actually know how to use a newsreader. So when you say something stupid, it's difficult for me to tear you a new one when it's not even apparent what you're referring to.

By the way, every time I click on the link forced upon CAF posters at the bottom of their posts (which supposedly provides the context to which their unquoted replies are addressing), it comes up with "server is busy." What kind of half-assed site is caraudioforum.com running, anyway? Clearly, the site maintainers have the same level of intelligence as the average CAF poster. >> > i couldnt help mentioning how fokin stupid the guy who asked the >> > dumdass [quoted text clipped - 17 lines] > site maintainers have the same level of intelligence as the average CAF > poster. it's not about intelligence, it's about money.. buy any web servers lately? hows you bandwidth bill?

No, he should be insulted for refusing to remove the link to RAC, and what's more, for stealing the RAC FAQ and posting it as his own, even against the wishes of the contributors and maintainer.

Don't you think the question was a little overly "broad", John. There's a bunch of sharp folks in here but you have to give us more to go on. Why are you asking the question? dave > >>His response was a good one...I will save you the trouble of having to look > >>it up urself: [quoted text clipped - 13 lines] > My eBay stuff: > http://tinyurl.com/u0fi It's a perfectly reasonable question, and I'm a bit surprised these trolls are hassling you about it. Essentially, an amplifier increases the amount of power you can deliver to your speakers. As you start to exceed the capabilities of the amplification in a car stereo (which tends to max out at about 15 watts per channel, despite the inflated claims by the manufacturer), distortion skyrockets because your signal is becoming saturated. At low volume levels, the difference is negligible.

You could wire a subwoofer into your stock system using a passive crossover, but there's no way the power from the stock head unit will adequately power a large subwoofer. Also, the passive crossover networks that come with component speakers consume power from the head unit's amp, leaving that much less for the speakers. I'm not talking about the little first-order crossover that separates the mids from the highs on a coaxial speaker, I'm referring more to the larger second- and third-order crossover networks, like the kind you get with MB Quart component sets.

True - everything in this business is subjective, but if you have a stock head unit that only puts out an honest 15W by four channels, I can't see passively connecting a 12- or 15-inch sub along with the rear speakers and being very happy with the results. >> Also, the passive crossover networks that come with component speakers >> consume power from the head unit's amp, leaving that much less for the >> speakers. > >eh? a little. Only a little, but it's still significant. The term is "insertion loss", and it can consume 10% of the amplifier power (or more), which is significant if we're only talking about a 15 watt-per-channel head unit to begin with. The insertion loss goes up as you add more and more passive components, so a 12db/octave or 18 db/octave passive crossover will consume more power than a 6db/octave crossover. Low-pass filters are the worst offenders, because the inductors used are made up of many turns of wire, and have a measurable DC resistance. This causes them to dissipate power in the form of heat while they're operating. Also, the lower the crossover point, the larger the DC resistance of the inductors will be. >>I'm not talking about the little first-order crossover that >> separates the mids from the highs on a coaxial speaker, I'm referring >> more to the larger second- and third-order crossover networks, like >> the kind you get with MB Quart component sets. >> >> Scott Gardner Scott Gardner MZ and the Scotts, Thanx for the serious replies. :) In short, I was getting some clipping when running from just my HU. Research showed that an AMP would help get more juice to the speakers when they needed it, therefore negating the clipping. Since my initial post, I've installed an AMP and some nice Boston Accoustics and Polks. TREMENDOUS difference! Take care, John in NH ~~~ If you're not annoyed, you're not paying attention. My eBay stuff: http://tinyurl.com/u0fi Adding an amplifier between the head unit and the speakers provides a huge increase in clarity, not louder sound. Louder is controlled by the volume. The output from a cd head unit is usually provided by a couple of integrated circuits. The real thing is usually called "discrete outputs", meaning transistor outputs. Car stereo dealers frown upon "deck power", and knowledgeably suggest an amplifier. Speakers are accoustic motors which run on wattage. If there is enough wattage, everything works fine, but if there is not enough wattage, when the music volume is increased, the sound will distort.. This is the condition preceding "clipping" where there is not enough "fuel" for the speakers, and much of the musical passage is not heard. It is not necessary to have an amplifier with hundreds of watts. Remember, more wattage doesn't mean louder, volume means louder. All aftermarket speakers (coaxial=midrange driver with a tweeter, or 2-way) are stronger built than o.e. ones and are four ohms impedance. All aftermarket head units have four ohm outputs to match the speakers. Very few companies (Bose) provide car builders with four ohm systems so replacing the junk head unit with a today technology CD head unit requires changing the speakers as well for a reliable, good sounding system.

They frown upon deck power because they make more money selling an amp allow with it. > Speakers are accoustic motors which run > on wattage.

This is the condition preceding "clipping" where there is not > enough "fuel" for the speakers, This isn't the condition preceding clipping. It IS clipping. Prior to the onset of clipping, there is virtually no distortion present, regardless of whether it's a McIntosh amp or a Jensen head unit. > and much of the musical passage is not > heard. It is not necessary to have an amplifier with hundreds of watts. > Remember, more wattage doesn't mean louder, volume means louder. Increased volume can only be obtained by more power. When you turn the volume knob up, you're increasing the input voltage to the amplifier (whether it's in the head unit or an external amplifier), which in turn increases the voltage output of the amplifier (which increases the power delivered to the speakers). > All > aftermarket speakers (coaxial=midrange driver with a tweeter, or 2-way) are > stronger built than o.e. ones and are four ohms impedance.

Mah, too tired today, 3 17 hour days working on an install and arguing with idiots about clipping and underpowering has taken it out of me. I'm sure our car audio rep for 8 years guy here will give me another chance :) Les > Mah, too tired today, 3 17 hour days working on an install and arguing with > idiots about clipping and underpowering has taken it out of me.
