Hello all, Merry Christmas.


I use 2 of these amps they are bridged for my Rti150 front speakers. One amp is still working both the HiTemp led is a little on (not really bright just half bright).

Is this a OH **** problem?

    Sounds like you're just warming up! :p

    Sorry, just had to... FWIW, if the hi temp isn't supposed to be on, I don't think it should be. Have you called anyone about it?

    Not a problem. Just a warning, at this point. Have you tried running them in biamp configuration rather than bridged and see if the results are the same?

    Will ok just is what I have done so far. I swapped the amps the problem followed the amps where on for like 5 mins, light on amp still working? Listening a little down not loud, amps aren't hot.

    The problem with bridged mode on the A23 is that it's only stable with 8 ohm speakers at high output levels (it sees an 8 ohm speaker as a 4 ohm load). When I had a pair of RTi150's, I suspected that they were drawing more current than a typical 8 ohm speaker would. Those woofers appear to be the hard section to drive on those speakers, and I wouldn't be surprised if their impedance dips closer to 4 ohms than 8 ohms. When the speakers dip to 4 ohms, the bridged A23 amplifier actually reacts as if it's driving a 2 ohm load. Very few amps are capable of doing that for extended periods. That's why I'd suggest using the amps to biamp, that way their output devices are more capable of driving lower impedance loads without over heating.
