Is 4 x 60W enough for my speakers?

That is a maximum rating, so expect less continuous power. It is fine for powering four factory-style speakers, but not for a subwoofer or high-power components.

Does it fit a subwoofer?

No. All four channels are rated for full-range speakers at 4 ohms; there is no bridged subwoofer rating or low-pass filter listed.

What comes in the box?

The amplifier, a fittings package with screws and a fuse, and an owner's manual.

Run 12V power and ground to the screw terminals, feed audio in from the head unit or a pre-amp, and connect speakers to the four outputs. Use the fuse on the power line.

Class A/B amps generate heat. The aluminum case has cooling fins and vent holes, so mount it where air can move around it.

What are its dimensions?

About 34 x 22 x 4 cm (13.4 x 8.7 x 1.6 in), so it is thin enough to fit under a seat or against a panel.
