The DS18 ZR800.4D is a four-channel Class D car amplifier rated at 200 watts RMS per channel into 4 ohms and 320 watts per channel into 2 ohms. Bridged, it delivers 600 watts into two 4-ohm loads, so it can drive a front stage and a subwoofer pair from one chassis. Class D operation keeps it smaller and cooler-running than the class AB amps it competes with, and DS18's ZR line is aimed at loud, budget-minded builds. It suits drivers who want strong output per channel without a bulky amp rack.
