Often when an amplifier is bridged there are some negative points, even though it has the potential of delivering higher power..
1. A bridged amplifier typically does not like driving low impedance/low sensitivity loudspeakers
2. The load presented to a bridged amplifier is significantly lower than 8 Ohms, which can cause the amplifier to mis-behave and its protection circuitry may be activated
3. When an 2-channel amplifier is bridged, both of its output terminals (+ & -) are above ground so it is not compatible with certain external switchers that use
common ground
If U truly want more power than try it 1st, and compare the sound quality between bridged and unbridged..
Just my $0.02...
