each channel is for a different speaker like if you have four speakers like a set of comps and a set of coax then you would need a four channel amp so it can diffrientiat the left and right side if thats helps any someone prob come on here and explain it betta

Theres not much to explain, each channel is meant for a single device. If you have more than one channel u can usually BRIDGE the amp. Mono Blocks are commonly used for a single sub setup. And for compenents 4 channels are most commonly used.

ok, i guess that makes sense.
little thumper, so you're saying 4 channel amps are used for a pair of comps? why would that be? shouldn't 2 channels be used since there's only one pair of speakers? one channel for each set?
you can use a 2 chan amp for components thats more of a common thing. some people also bridge a 4 chan amp, to run only 2 channels for more power.
or they run a 4 chan amp to power each speaker independly (mids and tweets on their own channel - being active)

i loled:laugh:
That diagram rocks.
To clear up the component thing:
Components can be run passive or active. Passive means the crossover is after the amplification. Active means it is before.
If you run passive, you only need one channel per set (usually 2 drivers, mid and tweeter).
If you run active, you need one channel for each driver (again, usually 2 drivers, mid and tweeter).
2-way is a mid and a tweeter on each side
3-way is a midbass, midrange, and tweeter on each side
So in a 2-way passive setup you would only need 2 channels.
In a 2-way active setup, you would need 4 channels.
In a 3-way passive setup, you would need 2 channels.
In a 3-way active setup, you would need 6 channels.
When running 3-way active, the midbass or tweeters are often run on a different amp, since 6 channel amps are not as common as 2 or 4 channel ones
I hope that makes some sense.
Bridging means taking two channels and using them to power one driver (can be a midbass, midrange, tweeter, sub, whatever). Usually a midbass or sub though. This is often done with a 2 channel amp to power one subwoofer. This is because most mono amps are class D, while most 2 channel amps are class A/B. This is a whole nother explantion though, so I won't get into that. It's mostly preference.
I hope I didn't confuse you more than I cleared things up. Just ask if you have any more questions, there are people here who know a crapload more than I do.

^^^ Well actually to complicate things even more, you can run passive before amplification, too. Passive simply means that the filter is not powered. The Harrison Labs F-mods and PF-mods are line level passive filters.
Active=filter uses a powered component (usually an op-amp) to accomplish filtering. Done before amplification because the circuit outputs are limited to low current.
Passive=uses unpowered componenets (capacitors, inductors and resistors) to perform the filtering. Can be done before or after amplification though the specific filter in question will only work one way or the other (pre or post amp).
