Some stuff just dose not make sence could use the help

Theirs some stuff that just dose not make since, and i need to put into stupiud people terms //content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif//content.invisioncic.com/y282845/emoticons/wacky.gif.cf4a48f9e6dfe9504ffd2c946fd2f340.gif

Ohms- could someone give me lamens terms i know it means 1 ohm = 1 amp of current but then i see 2 ohms load and 4 ohms load and i try to ask around and they look at me like im stupid, could someone just put lamens terms, also explane

something that i don't understand is something like an amp says it has 1200/2 then it says 220 wats per channel and then 480 1 channel briged, im like then if its 1200 wat amp why is it only 480, maybe something i don't understand but what happen to the other 720 wats?

if someone could explane this to me it could help me alot befor i make a mistake or assume something and then sound stupid later

~thanks

I was JUST about to attempt to answer you questions, but then "I" got confused too,lol.

A lot of amps are rated in Peak Power.

Like, they'll have a badge on the amp that says in big letters 1200 WATTS. But really it only puts out 300wrms per channel. And the peak is normally double the rms on those amps so each channel is 300/600 rms/peak. So if you add the 600's together, they can legally say 1200 WATTS, although you'll probably NEVER see it,lol.

Hope I've helped a little.

I'll try to re-read your post, and I'll post again if necessary, or someone else might explain better //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

for help with the first question:

Power(watts) = Voltage(volts) x Current(amps)

Voltage(volts) = Current(amps) x Resistance(ohms)

guys, he said lamen's terms.

Ohms: An Ohm is a measure of resistance in any electrical device, if you are savy with circuit boards resistors are measured in Ohms. now comes the catchy part, more resistance does not mean that the speaker is harder to move with an amp, you simply have to get the right amp. If you have a 2 Ohm speaker that you want to hook up to an amp you are going to have to get an amp that makes full power at that 2 Ohm rating.

Example: You have two amps, one MTX 1200.1 and one Orion 1200.1. Both amps make 1200W at full power, except the MTX does it at 2 Ohms while the Orion does it at 1 Ohm. Anytime you double the resistance (ie going from 1 to 2 Ohms, or 2 to 4) you will receive 1/2 the power from an amp (usually //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif ). So, with these two amps you will get either 1200W with the MTX (remember we have a 2Ohm speaker) or you can get 600W from the Orion, both have a maximum output of 1200W but the MTX is simply a better choice for your speaker.

One last thing and then we move to your other question. Using the example above, the MTX also has a drawback, anytime you divide the resistance (Ohms) in half (ie going from 4 to 2 Ohms, or 2 to 1 Ohm ) you will double the power from an amplifier. So, in this case at 1 Ohm the Orion does 1200W and the MTX a theoretical 2400W. The reason i said theoretical is because the MTX is only rated for 1200W, anything above that and it creates too much heat and burns up (literally) so if you have a 1 Ohm speaker the Orion is a better choice.

Peak Wattage vs. RMS Wattage: Simply put, only read rms ratings when shopping for an amp, if it doesn't say rms then you should just assume it is peak. In lamen's terms rms is simply the wattage the amp can constantly put out no without any issues, peak is a point in which the wattage spikes for less than a split second. RMS is good for rating an amplifier because 1. it is the true rating of the amp and 2. is harder to strectch the truth on (some are still exagerated, but not nearly as bad as peak ratings.) When shopping simply look at rms ratings only and use a little common sence, 1200W amps don't go for $120 //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif .
