Do I need an amplifier to use these speakers?

Yes. These are passive speakers with no built-in amp. You need a stereo receiver or amplifier, and the Bluetooth main speaker still needs power and a signal path to the others.

How does the Bluetooth work across four speakers?

Only the main speaker has the Bluetooth chip. You pair your phone to it, then wire the main and secondary speakers in series so the same audio plays through all four.

What size hole do they need in the ceiling?

The listing does not state a cutout diameter or mounting depth. Measure the speaker frame and check your ceiling cavity before cutting, since 6.5-inch woofers usually need a hole close to the frame size.

Can these be used outdoors or in a bathroom?

They are designed for indoor ceiling mounting. The ABS housing and rubber seal help with leakage, but the listing makes no weatherproof or moisture rating, so avoid damp outdoor spots.

How much power do they handle?

The 150W figure is peak power per speaker. Match them to an amplifier with modest continuous output per channel rather than a high-power amp, and keep the 8-ohm load in mind when wiring.

Are they good for surround sound?

They can serve as ceiling or surround channels in a home theater, but with one Bluetooth unit and series wiring they are better suited to stereo whole-room audio than to a calibrated 5.1 setup.
