4 Channel Class-FD Amplifier (4 x 150W / PRS)
The Reference in car audio amplification.
Part of the Pioneer Reference Series, this full-range Class-D amplifier incorporates ICEpower digital design, which initiates considerable efficiency and less distortion compared to conventional Class-D amplifiers. The result is power and clarity combined.
The PRS-D420 shares the same linear technology op-amp (operational amplifier) as our DEH-P88RS-II reference CD tuner, making a perfect pairing for high quality sound.
Installation can be as flexibile as you require; the top plate rotates 180 degrees to suite your mounting direction. Additionally, the speaker line input sensor automatically detects your speaker cables; meaning you can connect directly to the amplifier without a relay or other connections.
With an anti-resonance H-shaped chassis, the PRS-D420 has a tight, compact design (which also aids easier installation), without compromising power output and audio quality levels.
