The DS18 ZR1000.1D is a Class D monoblock amp built to drive subwoofers. It makes 1000 watts RMS at 1 ohm, 650 at 2 ohms and 380 at 4 ohms, so it suits a single or dual sub setup wired to a low impedance load. A 40-180 Hz low-pass filter, a 10-50 Hz subsonic filter and up to 12 dB of bass boost give you real control over the low end, and the included dash-mount knob lets you trim bass from the driver seat. Against rival monoblocks it stands out for 1-ohm stability and a full protection suite at this power level; the trade-off is that it is a bass-only amp, not a full-range one.
