I can't be the only guy who is experiancing this.. I run AR AR9 towers for mains and they are powered from my Onkyo TX-DS787 which is suposed to put out 100 true watts per channel @ 8 Ohms.. And it very well may put out 100 watts per channel at 8 Ohms but 100 watts must not be NEARLY enough because every time I crank the volume up (and I mean WAY up) the dang 787 kicks off and I have to power it back on. It seems to me like the heavy bass is what is causes the phenominon (and that would only make sense as it's the big drivers that hog all the power trying to move all that air) I am getting sick of kicking the receiver off I need seperate amps badly.. From what I figgure, the AR5 which is the *exact* same tower as the AR9 only powered, incorperated a Sunfire 175 watt RMS amp that it's sole purpose is to drive 1 10" sub.. So I am trying to power that same 10" sub plus 2 Mag Alloy 5.25 mids and a 1" Titanium Tweet all from a meesly 100 watts and it just AIN'T happenin! It's time I invest in 4 monoblocks! Anyone else have a similar problem?
