If you do as jasonbourne71 suggested, and switch the bridged amp back to stereo, and use one channel of each amp per speaker, you may find that it sounds better in an unbridged mono block configuration. You’ll retain the benefit of the separation of the mono blocks, and the power supply will have less responsibility. It may be subtle and is hard to predict how audible it will be, but I think it’s worth a try.
Bridged amps vs stereo vs monoblocks.
I don’t have any real issue, but I’m curious about how the bridging of an amp functions. I have a 80 W stereo amplifier, which can be bridged to provide 220 or so power into a load. This amp also has a hefty power supply which makes it work beautifully with my Magnepan’s. However, I used to have two of these amps bridged. One of which I lost due to it breaking so i replaced with an unbridged stereo amp, which I’m only using one channel. So what a strange hodgepodge of connections, right? It sounds great and I am have no problems but I’m curious if I was doing some thing that is easily changed to provide benefit. Mixing two different amps for example. Or I read when an amp is bridged it is sensing a four ohm load as a two ohm load and therefore what does that even mean? Also, using one part of a stereo amp is odd, but does that change anything, especially if there’s one power supply? Curious, if there any principles I could learn about this from those more familiar with those equations thanks!
