Review
I had always been an Pioneer fan, and these multi-channel amplifier had failed me not. I love blasting my drums-rich rock music in the car, and previous other branding amplifiers did not do a very good job in minimizing the distortions. Upon changing to the PRS-D4200F, I've enjoyed every single ride in the car. Not only does it give distortion-free music, low and high tones are also properly delivered. Installation of this multi-channel amp was fairly simple. Definitely something an audiophile would enjoy!

What I like
Distortion-free sound, along with delivering the extreme high and low tones brilliantly.

What I do not like
Really expensive, but something worth spending on!

I installed this on
Subaru Impreza

Review
I bought this unit as a birthday gift from my brother. I wanted a 4 channel amp so I could boost output from all channels without the cost and hassle of multiple amps. This produces plenty of power and is very stable. Warms up some, but so far I've run it for hours at a time without significant heat or any problems at all. I chose to wire this using the speaker-level leads from my head unit because I wanted to retain the ability to fade front to back. Turns out I never use the fader and the speaker level leads do generate a little bit of noise.

What I like
Provided me with a whole lot of power with definitely no distortions.

What I do not like
May take quite some time to install since it isn't easy to install.
