I have recently received a cheap Chinese Sub which was badly dinged up in
the delivery (thanks a bunch, DHL...) and another one is being sent for just
a tenner to cover the shipping charges. So I've taped this one up pro temps
and have had some noises out of it and will give it a good thrashing
shortly.
Anyway , the instructions are in German, so I've got some questions about
the connections, which look quite comprehensive - see:

Hmm, the back of your sub looks like mine, but with better speaker terminals.
Though I can't really complain for £40!
I take it the 'Hi Level In' and 'Hi Level Out' is where the speaker output
wires from a stereo amp are routed for a normal 'sub/sat' stereo setup?
(amp - sub - speakers.)
Yes. The speaker wires from the terminals on the amp go to 'Hi Level In' and the
speaker wires from the 'Hi Level Out' go to the terminals on the satellite speakers.
What about the 'Line In' and 'Line Out' (which I have never seen before) - I
presume the single SW phono connection from the AV amp can go to either of
the Line In sockets and they are 'commoned', but what are the 'Line Out'
phono sockets for?
possibly a connection to the power amp, if the pre-amp only has one 'pre-out'
socket?
Finally the Phase Switch - I haven't
heard much difference with either setting yet. Is there a 'correct' setting?
I haven't heard a difference in mine either. I believe it depends on your
listening room condition and the distance between the sub and satellite speakers.
I have a M&K sub manual and this is what they say about phase
"the phasing test ensures optimum sound in the critical bass frequencies where
your sub and sats overlap.
Play a familiar CD/LP with steady consistent bass. Listen carefully to the
mid-bass (75 - 125Hz) region - the part of the specturm where electric or string
basses and drums are found. Move the phase switch to the opposite direction. Now
listen to the same musical passage again. If you hear less bass, the original
connections were correct. If you hear more bass, the new connections are correct"
