for a friend really. mate has a new head unit with a sub out but the
head unit sub out is a single RCA but his sub is a double? he 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
