Does the system include an amplifier?

No. The satellites and subwoofer are passive speakers, so you need an amplifier or receiver to drive them.

Can I use it with a phone over Bluetooth?

Not directly. The system has no wireless streaming built in; add a Bluetooth or Wi-Fi streamer, or use a receiver with those features.

It is designed to be buried or concealed in the yard, with wire run back to your amplifier.

It is a 2.1 system: two stereo satellite speakers plus one subwoofer for bass.

The added subwoofer gives noticeably more low end than two rock speakers alone, at the cost of extra wiring and a hiding spot for the sub.

Yes, it is built as an outdoor system, though you should follow Sonance's guidance for drainage and wire protection in freezing climates.
