How do I install a subwoofer if I don’t have a preamp subwoofer?
If your receiver doesn't have a preamp output, you can treat the subwoofer like another speaker and use speaker wire to connect it to the receiver's speaker terminals designated for the front left and right speakers.

Do you need a power amp with a preamp?
Yes, you need both. A preamp doesn't have the power to drive a speaker; a power amp is needed for that. A power amp expects a signal at line level; a preamp is needed for that. You could technically go from a preamp, straight to active speakers without an external dedicated power amp.
Can a preamp power speakers?
A preamp cannot power passive speakers; you need an actual amplifier. While they are similar devices, and you can use them together or an amplifier by itself, a preamp isn't strong enough or designed to be used as a standalone amp with passive speakers.
