Very vague question. Are you asking how to hook up a sub to a pre-amp ?

Hi and welcome.
Here's a briefing for you on captioned subject.
An AVR (Audio-Video-Receiver) of today will always have power amplifiers "on-board" for all the speakers (sometimes also called satellites) in your system, but will only have a pre-out (so called line-level output) for subwoofers becasue subwoofers of today are built with so-called plate amps, i.e. a separate power amplifier inside the box of the sub referred to as active subwoofers (amp + driver in the same box).
The simple reason is that most of the time the plate amps will have a relatively higher power output than the AVRs have for the individual speakers, coz it takes a lot more energy to produce deep and loud bass with drivers having a diameter of 12-15-18" than it takes for the higher spectrum speakers.
Hope this helps.
