Hi, I have a few questions that are really confusing me. My first question is, could I use the speaker from a component set as my rear coaxial speaker (i.e. the speaker without the tweeter)? Or do I need to specifically use a coaxial speaker for the rear in order for it to sound good? Secondly, I am going to be running my speakers off an orion 200.4 cobalt amp which does 50X4 at 4 ohms. My front components are rated 100RMS at 3Ohms (orion 6.5 P series). I have never heard of amps specifically being able to output 3 ohms and I am wondering if this will work or if it will screw up my amp? I am also wondering if that amp will be powerful enough to run the speakers or if I need a more powerful amp? If the 3ohms thing works, then could I have coaxials in the rear that are 4ohms, or can you not mix and match like that? (the 200.4 will be powering the components and the coaxials). If you can mix and match since the amp is rated at 4X50, how does that get distributed if the fronts are 100RMS and the rear coaxials are RMS ~50. Would the power get distributed accordingly or would it still be distributed exactly equally?

the rear speakers arent coaxial anyway. you can put components back there, but depending on your ride you may find no one makes one that size. I have never seen a 4 inch component set, which is what the e36 uses. If the components are rated at 100W RMS, then you should at least give them 75W RMS. If 100W is the top, and there is a manufacturer specidfied range, then 50 may be ok. As a rule of thumb you want your RMW to be at least in the top third. Power is distrubuted equally among all channels. No mix and match, unless you bridge, which wont do aything since you'll have to wire in parallel and negate any gain.

The three ohm thing is new to me.

dont worry about the compent speaker in the back as long as you have the cross over with it you will be fine because you dont want high frequency going thro it because that will fry the component.

o and if your talking the other way that you wanna put a two way speaker in there then you will have to bypass the factory cross over because the speaker will only get mids or only get highs if you dont
