Our take on the Diamond Audio DMD1000.1D Class D Mono Amplifier

The Diamond Audio DMD1000.1D is a Class D mono amplifier rated at 1000W RMS at 2 ohms and 680W RMS at 4 ohms. It packs a 4-layer FR4 board, balanced differential inputs, a 35–350Hz crossover, phase control, up to 18dB bass boost, and a remote bass knob into a compact chassis. It suits drivers powering a single high-output subwoofer who want clean bass without a big footprint. Against pricier monoblocks it gives up some power and premium parts, but its feature set is complete for the class.

Questions and answers

Is the DMD1000.1D powerful enough for my subwoofer?
It delivers 1000W RMS at 2 ohms and 680W RMS at 4 ohms. Match those figures to your sub's RMS rating; a single 2-ohm sub or a pair wired to 2 ohms is the sweet spot.
Can I use it in a boat or off-road vehicle?
No. Diamond Audio does not rate it for marine use, so it is best kept in a car where it stays dry.
What controls does it have for tuning bass?
It has a 35–350Hz low-pass and high-pass crossover, adjustable phase, up to 18dB bass boost, and an included remote bass knob.
Does it come with a remote bass knob?
Yes, a remote bass knob is included so you can adjust bass level from the driver's seat.
