Amplifiers: RMS vs. Peak Power

There are several differences between RMS and peak power and so it is necessary for the consumers to know the difference between the two. An RMS calculates the alternating current that flows through. Anyhow, it is calculated on an average. The whole process is not complex and does not require much of a calculation. RMS is the power that is transmitted continuously. This power should be just sufficient, so that the amplifier just handles it safely. In case of peak power, the burst of power is ins...

according to me the rms value is use in practical life

not really - say you have a sudden burst of power, and its 10 Watts above the max that your system can handle, your amp is gonna blow a ues. not nice if you are in the middle of a 12 hour drive.

thanks for your explination - I had no idea about this and it was confusing me - now all i need to do is to save and get a good amp and some speakers and then try to wire them to my car!

Hi aga in phpdev - have you decided on the speakers and amp you are going to get yet ? and have you got any idea how to connect them to your existing system ?

[phpdeveloper]

nope, I have no idea on the types of subs that im going to buy, all i want is something loud and bassy, does the kind of amp i get really matter ??

[fronk69]

yeah, the amp has to match the speakers (or the speakers have to match the amp) you can get them in kits where all the components are matched to each other - the kits tend to cost a bit more, but you can be sure that all the components work together well

ok, ill have a look - im looking on ebay just now for some parts - and all the things that im seeing are like a tenth of the price i thought they were going to be -
im looking at theis - is it any good ?

from the spec it looks quite good, but it depends on the price it is - if its a cheap amplifier then it might not actually give that output - but if its made from good components then it might be very good, make sure that you get 2 ohm speakers for it though - these will be louder.
