Can a BT2180 power 4 speakers?

The only concern I would have in reality is the way that you would set it all up. Those pioneers need POWER (ask me how I know) and I dont think that either option will actually be enough to push those pioneers. In my opinion, they need about 125 watts of clean power in order to come alive. I would probably let the 2180 power the front channels and just get another amp (maybe the soundstream TN2.600) to push the pioneers or vice versa. If you choose the second option (running the 2180 to the pioneers and another amp for the fronts), I would NOT get the TN2.600. That amp will put out way too much...and correct me if im wrong.

or you could run the speakers in series and keep the load at 4 ohms and that would break down to 90 watts per speaker. I would run it in series to be on the safe side. I just cant see an additional 25 watts making THAT much more of a difference...but I have been wrong before.
I would suggest running parallel, but you will lose the ability to fade front and rear. although you could put left channel front and right rear but I would not do that...
I agree with the Pioneers needing POWER... running 5.420 right now and I feel they need more power than that... not that they sound bad

Eshaw301... running two 4 ohm speakers in series will result in 8 ohm load. AFAIK it will then not get 180 Watt per channel but less...

If not a performance issue, why not? I'd rather have the fade ability than left/right balance on a motorcycle?

The front speakers will always give you "more" sound (mids/highs) simply because they are projected at you (that's why I duck into my fairing lol).
You will hear your rear speakers but to me it is more "filling" the sound around you... and in my case bass (pioneers)
or... you can always convert your mp3's to mono

Question, when you wire the speakers in parallel do you get the same volume out of all speakers, even if they are at different efficiencies or ohm ratings?

unless speakers are same brand and type, IMO no... too many factors play a role like efficiency (DB rating), ohm (2, 2.7, 4, ...), Size (8 inch will move more air than a 5.25), frequency (there are "no" speakers that perform as a "flat line" across the frequencies the speaker "supports" - we call it coloring, like guitar speakers color on purpose).
if you parallel 2 4 ohm speakers, they will in essence get the same power, but then the efficiency and other above mentioned factors will kick in...
hope this helps
