Power Amplifier
Why does pro audio/dj power amplifiers have way more power for cheaper than home power amplifier?
Just looking for a basic high power amplifier for a simple 2 channel stereo system. Would rather have seperates (power and pre amp) with a lot of power than a receiver. How come pro audio looks like a much better deal?
Because most likely you also have to buy allot of stuff for it and also Comsumer amps are probably allot mo compplex. DJ amps are usually very simple (to make) where as comsumer amps also have allot of built in components to make it easier for th customer.

Auto Sound System Amplifier - Tips To Pick Your Best
Setting about to find the best Amplifier for your sound system could be a whole lot simpler if you just dedicate sometime before hand to learn what is best for you and will perform best with your type of car, truck or SUV's audio system. It's worthwhile to learn about the functions of an Amplifier for you to make an informed purchase; the major function of an Amplifier is that is receives small sound signal from your auto sound system and increases it to produce louder sound. This means that the more powerful your Amplifier, the more exceptional quality sound it produces. A lesser-powered Amplifier will therefore have a weak, thin sound that is quite unappealing in any auto sound system and most other sound system as well.
It is also worth mentioning that power rating of an Amplifier is determined by the utmost power it's able to expend and not by it's regular usage amount. RMS rating is a good indicator of an Amplifier power output. Another thing to consider is that never purchase an Amplifier based only on RMS rating or maximum output. This number can be remarkably misleading in Amplifier purchse.If your preference is towards a thumping driving bass beat, then ensure that your Amplifier is equipped with a bass boost button. Such a button will be a plus in giving you a bass boost. I sure believe this is a must have to most bass lovers. Not every Amplifier is equipped with this, so shop smart in accordance to your likes.
Amplifiers are essentially divided into four main classes (but of course, there are many more classes, though mostly uncommon, so I will not dwell much on defining them) which represent excellent quality you ought to expect from the system.
A) 1. This is a class with amazing production of superior sound, but the down side is that it wastes large amount of energy in producing that good quality sound.
B) 2. This class is somewhat better than 1 as far as energy consumption is concerned, but it is a bit worse as it produces lesser quality sound.
C) 1/2. This is like a cross-breed between 1 and 2 because energy and sound wastage depends on the volume. Low volumes will use the class 1 attribute of the Amplifier while higher volumes are more in maintaining with class 2.
D) 3. This is mostly decent in producing good quality bass sound and nothing more. The quantity of sound and energy wastage is both moderate and is neither very impressive.
This is of course a skeleton run through most of the core amplifier basics. It is also worth noting that a score of people these days talk of amplifiers as just Amps, instead of fully pronouncing the entire word Am-pl-i-fi-er, maybe it's too long for most folks or just a hype. It's probably a slang widely accepted that no one would blink an eye if you utter it. Infact if you go the so-called old way and call it AMPLIFIER, don't be surprised if you get funny looks. Despite of all these, Amplifiers aren't the end to all that would be of an automobile sound system. its necessity is determined by you the consumer, because as a matter of fact most audio sound system work well, minus the extras like an amplifier that only serves to justify the price raise.
A decision to buy an Amplifier for your latest auto sound system, truck or SUV is at one moment filled with excitement and exhilaration, because this is habitually a decision that you have introspected over time. This same excitement can result to fear at later stage, due to the absence of clarity in what you truly need. I presume that this has at least gone a distance in informing your decision on whether or not to purchase an Amplifier, and if your answer happens to fall in the affirmative, you will ultimately make an informed decision prior to purchase.
