Amplifier has 2 channels, can be bridged into 1. However I have 2 subs, would it be louder or powerful if it is switched as bridged (mono)? or the overall power will be stronger as 2 channels (unbridged).
basically is the same, you're just transfering the power from a channel to another. All amps work at 4 ohms bridged (there are exceptions). It depends of wiring configurations panamanian.
