Does it come with a power supply?

No. The box holds the amplifier and an instruction manual only. You need to supply your own DC 12V/2A adapter with a US standard plug.

Can I connect my phone over Bluetooth?

No. The amplifier has no Bluetooth. You connect a source with a cable.

What speakers can I use with it?

It is rated for 4-8 ohm speakers and drives two speakers plus one subwoofer.

How much power does it really put out?

The RMS rating is 20W per speaker channel plus 40W for the subwoofer. The 200W + 200W figure is peak power, not continuous output.

Can I use it in a car?

Yes, it runs on DC 12V, so it can work in a car audio setup as long as you provide a suitable 12V supply.

Is it good for a desktop setup?

It is small and metal-cased, so it fits a desk well, but plan for a wired source and a separate power adapter.

Our take on the Artudatech 2.1 Channel Hi-Fi Amplifier 80W RMS DC 12V

The Artudatech 2.1 Channel Hi-Fi Amplifier is a small aluminum-bodied amp that drives two speakers and a subwoofer, rated at 20W x 2 plus 40W RMS and 200W + 200W peak. It runs on DC 12V and needs its own 12V/2A adapter, which is not included. There is no Bluetooth, so every source connects by cable. It suits a desk setup, a car audio upgrade or a small passive-speaker system where space is tight and a wired source is fine. Against typical mini amps it offers a dedicated subwoofer channel and a metal chassis, but it gives up wireless input and the convenience of a bundled power supply.
