The PLX1802 is an excellent choice for users who need to drive up to four
loudspeakers from each amplifier channel (2 ohm loading), or when extremely high
power bridge mono operation is required. The PLX1802 features built-in subwoofer
processing, filter switches, and front panel indications of bridge mono status.
