This marine receiver has 4 zones that each have independent volume control. There are 3 zones for full range and a 4th zone for a subwoofer. Here is how it works. Zone 1 is the built in powerful 4 channel amplifier. With the addition of an external amplifier you can use the additional zones as follows: Zone 2 controls a full range set of RCA outputs. Zone 3 controls a second set of full range RCA outputs. Zone 4 controls a 3rd set of RCA outputs that are dedicated for subwoofer(s). You can control the volume in each of those zones both from the unit as well as from the included wired remote. 3” TFT display Our built in 3” TFT display is crystal clear and it makes it easy to navigate your tracks and settings.

The RMS power of the built in amp is 28 watt x 4 channels! It is crazy loud and can be heard over the sound of the wind when you are on the water!
