for a friend really. mate has a new head unit with a sub out but

tried a
splitter but that didn't work, is there a special way to wire it
up?

How many amps is he using to run the subs , and is it 2 drivers in a
single
cabinet with 1 or 2 sets of speaker terminals?

Top marks Dr Zoiderg, it's amazing how many folks can give an answer
without
getting the full facts 1st.



Dont think either of you asked good questions,

Vamp you dont mention the fact he has a amp, does he have a amp? the sub
doesnt use RCA inputs it uses normal speaker connections + - . the amp's
job
is to convert the RCA output from the headunit and split the signal or
bridge the signal between X number of channels speakers.

If he has an amp....

First thing is make sure you got signal coming from the single rca, I
don't
recall ever seeing a single RCA on the back of a headunit but I could be
wrong, get your self a old ****ty speaker and plug the amp into it, if u
got
noise you got signal. if you have no sound then I would imagine you dont
have the setting in the headunit set to use the channel, if there is
sound
coming out then it will be a speaker problem on the sub end, double
check
the connections, then report back.

If he dont have an amp....

Go buy one :)



thanks ronny, the nob turned out to be using a DVD head unit but without a
TFT display yet and when
he plugged a monitor in he found out the RCA outputs had to be turned on.
all sorted now.

oh and i wired my own sub up tonight and my earth wire was red too :)

Glad you got it sorted, out of interest , why did you wire the sub to earth?

in built amp i think and when plugged in using a splitter he gets nothing,
i'm just going by what my
mate has told me, haven't been to see it yet.


Your mate would appear to be doing something wrong then. Normally with a
single sub out lead running to an amp (be it separate or built into sub) one
would either use a Y splitter to feed both L+R RCA's on the amp, or on more
upmarket amps you would plug your single lead into the L terminal and have
a switch which sums the signal from the L RCA and adds it to the R and works
that way.

The poster later admitted he was trying to get audio from a composite video
output.
