I'm from Croatia and I recently purchased Citroen C4 Coupe 1.4i 16V.
The model I purchased came with the "RDS stereo radio/CD player" and 4+2 loudspeakers installed.
Now, I have one question for you.
I want to install my active subwoofer but I presume that the build-in stereo has no subwoofer pre-out (or any pre-out at all). I cannot connect it parallel with rear speakers as well because the signal is too strong. The other option is replacing the unit, but that is out of the question also because I'm controlling some of the car options as well as time/date with the unit.
Do you have any idea how to connect the subwoofer to that system?
Thank you in advance for your answer!
