Is 50x4 better than 200 Watts alone?

I'm confused, last time I did math, 50 x 4 = 200. Elaborate on what you're trying to ask.

First things first. MOSFET does NOT dictate the type of power supply is being used. Metal Oxide Semiconductor Field Effective Transistor is an amplifier design type device, compared to a Bipolar Junction Transistor device type.

All headunits now use MOSFETs, a BIG marketing scheme to get consumers believe it's a better end product, capable of claiming to produce a ridculous 60W/channel on a headunit. Right...

You won't find a difference between the Pioneers 4500 or 4600, I guarantee it. Remember, larger numbers indicate larger output, so always market something with larger numbers.

Installation should be easy.
