What is bridging an amp and how does it work? And what should i expect from a bridged amp?
In oversimplified layman’s terms, when you bridge an amp, you’re harnessing the power of two channels to drive a single channel. You can sort of imagine this as gaining power by setting the channels to push and pull with each other to combine their power, instead of each pushing and pulling alone. This does however put more strain on the amp and thus you will be limited on the speaker impedences (resistances) allowed. This is what is being referenced when an amp is said to be 2-ohm mono stable. When you bridge two channels in an amp, you will end up with only one channel. In general, the amp will run hotter under these conditions, but the power produced by the bridged amplifier will generally be more than two times the power of a single channel alone, and can be up to four times the power of the single channels.
