Pioneer DEQ-2000A 4 Channel DSP Amplifier 160W Bluetooth Processor

The Pioneer DEQ-2000A is a 4 channel DSP amplifier with 40W RMS per channel, a 31 band EQ and Bluetooth input.

Factory head units are hard to replace in many new cars, so it takes speaker level inputs. Pioneer combines a 4 channel Class D amplifier with a DSP, so time alignment and EQ happen in one compact box under a seat.

Problems it solves

• Sound that comes from the nearest door. Time alignment centres the image on the driver.
• Bass and treble that clash in a small cabin. A 31 band graphic or parametric EQ sorts it out.
• A system that may grow later. Six 4V preouts can feed more amplifiers.
