The SQ600.1D makes 600W at 1 ohm for a single IDQ or a modest IDMAX build, and the SQ1200.1D makes 1200W at 1 ohm for a hard-hitting IDMAX 10 or 12.

The SQ600.1D, SQ800.4 and SQ1200.1D are Class D, the SQ800.4 being a full-range digital design so it runs the front stage as well as the sub stage. Class D keeps them efficient and cool, and the SQ tuning keeps the filters and ratings honest.\u003c\/p\u003e\n\n\u003ch3\u003eDo these amps match Image Dynamics subwoofers?\u003c\/h3\u003e\n\u003cp\u003eThat is what they are built for. The SQ monoblocks are sized to the IDQ and IDMAX lines: the SQ600.1D for an IDQ or a single modest IDMAX, the SQ1200.1D for a full IDMAX 10 or 12.
