A bridge-parallel amplifier configuration uses a combination of the bridged and paralleled amplifier configurations. If you are doing sound in mono, you could put the CS-800X in bridge-mono mode to power both SP-2XTs, connected in parallel across the amplifier's two red binding-post terminals. At maximum power, the 8 Ohm loudspeaker now "sees" Generally, a stereo power amp is used, so when connected in bridge mode we are assured that the amplifiers are more or less identical. information is to be found. width: 100%; very real possibility of destruction of the output transistors.
