What are the differences in mono amp and 2 channel bridged amp?
there are no cons, the only pro is you “double” the output (but not really, you just put all the wattage on the same “channel” When you bridge an amplifier, you combine the power output of two channels into one channel. Bridging allows you to drive one speaker with more power than the amp could produce for two speakers. Because of this high power output, bridging is an ideal way to drive a single subwoofer. for subs you want mono class D they run cooler than multi-channel amps because they are designed just for low frequencies (bass) Mono (or monaural) amplifiers are single channel amps, well suited for low-frequency (subwoofer) applications since the human ear cannot distinguish stereo in the extreme bass range. Also, since mono amplifiers are stable to 2-ohms, you can connect them safely to two 4-ohm woofers (wired in parallel). Class D amplifiers use output transistors as switches to control power distribution — the transistors “turn off” when there is too much voltage across them.
