ratings.....

if a speaker says 4ohm, does that mean it can be run from 1-4 ohms, or 4+ohms? or does it mean that it can only be run at 4 ohms?

thanks

Holy crap, didn't you understand my last post? It says 4 ohms because that speaker causes a 4 ohm load on the amp. It can be run at .00001 ohms, or 1 million ohms. If you wire 2 speakers in parallel, the circuit load will be 2 ohms, whereas if you wire the speakers in series, the load will be 8 ohms.

Or in other words, if you have a speaker and its voicecoil is rated at 4 ohms that will never change. You use this 4 ohm rating of the speaker to put a different load on the amp. More speakers will get you different loads causing the amp to put out different amounts of watts. Make sense?

ok i understand, somewhat. what i need to know now is, so if i wire the speaekrs up in parallel it would make the load 2ohm on 1 channel. and i could run the sub on the other. What i need to know is would that blow my speaekrs as my bud told me to run 1 speaekr per channel

Ya gotta give us more info man. How many watts your amp puts out into what ohms and how many watts your speakers can take and just stuff like that.

speakers: 6x9 600W, 300RMS

amp: 800W

280W x 2 (at 4 ohm)
400W x 2 (at 2 ohm)
800W (mono) at 4 ohm

Ok, so wire each speaker to each channel, that way the amp will be giving each speaker 280w, which is 20w shy of there recommended input. You cannot wire a speaker on one channel and a sub on another.

Actually you can do that, you just would not want to. If you have 3 speakers that you are trying to run, list the speakers and type of speaker they are. What impedence are they, what is the amp. Never in all my years have I come across a 300w rms 6x9" speaker as well. They must have liquid cooled oversize damped and crossported voicecoils in to handle that kind of power.
