RA25 & RA30
NOTE!
The amplifiers are two (2) ohm stable. In stereo
mode it´s possible to load the amplifier down to two
ohm on each channel.
In mono bridge mode it´s possible to load with one
four ohm fullrange speaker or subwoofer.
The sub channel on RA30 can handle 2 ohm loads,
for example two 4 ohm subwoofers in parallel.
In bridge mode connection an amplifier sees a four
ohm speaker as a two ohm load.
