Lets say you have a 2 channel amp that does 100 watts RMS per channel at 2 ohms. Does that mean each channel can take a 2 ohm speaker or a 4 ohm speaker on each channel which as a whole would drop it down to 2 ohms?
lets say, you have a 200 x 2 @ 4 can you run a 4 ohm speaker on each channel or do you have to run an 8 ohm load on each channel, basically is a two channel amp basically 2 amps in one unless its bridged?
lets say, you have a 200 x 2 @ 4 can you run a 4 ohm speaker on each channel (YES) Each 4 ohm speaker would get 200 wrms. If you ran an 8 ohm speaker, then it would recieve @ half or 100wrms per channel. If you bridged both channels you could get 400wrms X 1 @ 4 ohms, or 2ohms or 1 ohm, or .5 ohms. This is all hypathetical unless you specify what amp and the specs of it.
