A4 Saloon Aftermarket stereo problem
I have a 05 A4 B7 Salloon and have replaced the Concert Headunit to a Kenwood cd player, I have used a connects 2 iso harness which supplies a switched 12v supply. It uses the kenwoods preouts to supply the rear outputs through the Audi amp.
My problem is there is very little bass coming from the rear even with the bass on full on the headunit, the front is fine.
What I would like to do is to tap into the audi amp and run rear speaker cables from the headunit and use the sub preout on the headunit with the LPF switched on for the sub in the parcel shelf still being powered by the audi amp.
Where is the amplifier located so I can do this and which cables do I need to tap into.
