Can anyone advise or direct me regarding the wiring set up on the standard stereo in my 2012 xc90. what I am trying to find out is if the amplifier signal is at preout level or speaker level as looking at upgrading speakers and amplifier plus adding a sub using an original enclosure with an 8" dual coil sub.
I don't want to change the original stereo facia as I think it suits the car and has every function I need except DAB which is easily added via either the usb input or the aux input.
Stealth wins as little darlings don't want to break in to it and steal the hifi if it looks standard. either advice or link to a wiring diagram would be much appreciated.
thanks ( first time Volvo owner )
