As I understand it when you bridge an amp you will double its output at 8 and 4 ohms, but not 2 ohms. If your speakers dip to 2 ohms, depending on your speakers design (and listening levels?) their output potential (sound) may be compromised. FWIW
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!
