Could some one give me the lowdown on mono channel and multi channel. I know that you can take a four channel amp and bridge it to a three or two.
Yes you can. The Clarion APX1300 that I have has 4 terminals (2 positive, 2 negative). When your running one sub, you can bridge it. I'll post a photo of the setup from the manual providing my digital camera's batteries don't die on me now.You can't bridge a single mono amp.
But every thing else is pretty much dead on.
Basically, mono amps are made specifically for subwoofers, they only output a narrow band of frequencies which are all in the bass ranges around 1-150Hz, they also use different technology, as most mono amps are class d, which is around 70=80% efficient whereas multi channel amps use class a/b, around 50-60% efficient... Multi channel amps can be used to power speakers or subwoofers, and they provide the full range of audible frequencies 1-20,000Hz.
I'm tired of typing long sentences... Well. Yeah.
Theres a diffrence in mono block class d amps and reg mono blocks, some mono blocks have more then one channel, mono class d only has one. IMOYes you can.

really? got an example of a multi-channel monoblock? or are you confusing a single case with two monoblocks in it as "multi-channel monoblock"?Theres a diffrence in mono block class d amps and reg mono blocks, some mono blocks have more then one channel, mono class d only has one. IMO
so with a mono amp you can run two to three or even four subs?
You can run up to infinity subs (not the company), technically speaking, whether the amp will be able to handle the impedance load or not is a whole nother story.
You can run as many subs as you want off of a monoblock amp, because it's a stupid amp, and no matter how you hook up the speakers to it's terminals, as long as you have both polarities taken care of, you'll get the same results. Just don't let the overall impedance drop below what the amp can handle, and with most common powerful monoblocks, that's 1 ohm, and well built and underrated ones can dip a little below 1 ohm.
(Tip, don't take your Sony Xplod mono amp, and try and wire it below it's rated minimum resistance, it will Xplode!)
I would love to see a one hooked up to a .002 ohm load, strapped with multiple runs of 3/0, to provide all the juice we can get, a constant 16 volts, all protection circuits disabled, with a knife for a fuse, pioneer deck with bass maxed out, volume at 62, then lets run a 43 hz tone for everyone. Would it really xplode?
Once again, you cannot bridge a mono amp, if you can, it's not a mono amp. Even if it has 384 speaker terminals, you cannot bridge a mono amp.

Wow.... Now i have definitley heard it all.Theres a diffrence in mono block class d amps and reg mono blocks, some mono blocks have more then one channel, mono class d only has one. IMO

a channel is simply a distinct audio signal.
concider stereo. two channels. to play stereo you would need two seperate channels becuase the sound out of the left speakers might be different then the sound on the right channel.
then expand this to 5.1 audio. SIX channels, as there are different signals for front and back for both left and right, and there is a low-frequency and a center channel.
then 7.1 audio, even more seperate audio signals.
but its not just seperate signals from the source, but also modifications to them that can make use of multiple channels. think of a car stereo. two channels of audio, left and right, but four speakers. two channels are required, and you could hook up the front and rear speakers to these two channels, but it is desirable to have four channels, as it may be desireable to have a different volume setting for the front and rear speakers.
note that i'm only talking about DISTINCT signals. lets say you have four woofers. there is no need for four channels. at most two channels would be required, and a single "bass" channel would be all that is usually needed as bass is not overly directional.
