so since my speakers are being run by the head unit and the amp is 2 channels bridged @ 4ohms (runs 300wrmsx2 from phoenix gold)apparently, I have:
4x22=88
+300x1=300
--->388wrms

now, if I ran the two back speakers on one of the remaining 2 channels, would they be running at 4ohms also? PG website says 4 ohm stereo is 75x4. then, would I have(?)

2x22=44
+300x1=300
+75x1=75
--->419wrms

or should I run each of the rear speakers off of it's own channel (since I have 2 remaining), which would add another 75 watts to the above (which is bad for what my intent is). Thanks.
