How much power does the ZR600.4D make?

It is rated 150W RMS x 4 at 4 ohms, 240W RMS x 4 at 2 ohms, and 400W RMS x 2 bridged at 4 ohms. The 2400W figure is peak, not RMS.

Can it run four speakers and a sub?

It has four channels. You can run four speakers, or bridge two channels into a 4-ohm sub and use the other two for speakers.

Each setup can be switched to full range, low-pass or high-pass. There is a gain knob but no bass boost or subsonic filter.

Class D is efficient and compact, but this amp's 1% THD is higher than premium full-range amps. It is fine for most car audio systems.

Power and ground terminals accept 4-gauge wire, which suits its current draw.
