Line driver?
 

Got a Sony MEX-1HD in a 2003 Audi A4 Quattro...

I'm running the front channels plus sub from a Sony XM-4060 amplifier.
Rears are running off the Audi active speaker system. However, the gain
of the rear amplifier is quite a bit lower than the "standard" gain,
whatever that happens to be. (I normally set the gain so the level is
the same as using the head unit's onboard amp.)

Now I've seen this gadget:

which looks like it'll increase the level on the rears to match the
front, but it has 3 outputs, which is two more than required. However,
I've been informed that hooking a line driver up to the head unit end of
a long cable (5m or so) can improve the sound quality.

So, two options. Firstly, anyone know of a unit similar to the above
that has one set of outputs rather than 3. Alternatively, is there a
unit that has two sets of inputs and outputs, so I can boost the signal
for the front and rear channels?

At a push I could just fit this unit to drive the Audi active system of
course.
