Is this amp Class AB or Class D?

It is Class AB. That design is simple and clean but runs hotter and draws more current than a Class D amp of similar output.

Can it power a subwoofer?

Yes. The two channels bridge into one channel, which is the usual way to drive a subwoofer from this amp.

What do the 300W and 600W figures mean?

They are maximum ratings: 2 x 300W at 4 ohms and 2 x 600W at 2 ohms. Continuous RMS power is lower, so match speakers to the RMS rating.

Does it need extra cooling?

The aluminum shell and ribbed top dissipate heat, but Class AB amps still need open air. Mount it where it gets airflow and keep the fuse accessible.

What connections does it have?

RCA inputs, gain control knobs and a switch on the side panel, plus speaker outputs. It is a line-level amp, so it needs a head unit with RCA preouts.
