Can it power a subwoofer?

Yes. Bridge the two channels into one and it can drive a single subwoofer. Check the sub's impedance and power rating against the amp's bridged output before wiring.

What is the difference between Class A/B and Class D?

Class A/B amps like this one generally run warmer and draw more current but are simple and inexpensive. Class D amps are smaller and more efficient, which matters in tight installs.

Does it come with a wiring kit?

The listing does not state that a wiring kit is included. Plan on power and ground cable, a fuse, RCA cables and speaker wire separately.

How much power does it put out?

The description gives no specific RMS or peak wattage figures. Ask the seller for the rated output per channel and bridged before matching it to your speakers.

Will it fit in my car?

Its footprint is about 11 by 10 inches and roughly 3.5 inches tall, so measure your mounting spot, such as under a seat or in the trunk, before buying.

Our take on the KFFKFF 2-Channel Car Audio Amplifier, Bridgeable Class A/B Full Range Stereo Amp

The KFFKFF 2-Channel Car Amplifier is a bridgeable Class A/B full-range stereo amp in an aluminum case. It drives a pair of speakers or, bridged, a single subwoofer, and the aluminum housing is meant to shed heat during long drives. It suits budget-minded drivers upgrading factory audio or adding a small sub. Against name-brand two-channel amps it is a basic, low-cost option: it lacks the tuning and protection features of premium rivals, and there is little independent testing or owner feedback to confirm its rated output.
